Recharged Car AC still warm? (Solution)

If the A/C works okay then gradually blows hot air after recharging, you might be dealing with refrigerant leaks. The safest and effective way to find leaks is to vacuum the system. Take your car to a qualified technician to have the system diagnosed.

Why is my AC not cold after recharge?

The Compressor is Unable to Connect It could be an electrical failure in the circuit during charging, overheating vehicle, or maybe the coolant is just low. So, make sure that you check the compressor as it could be the reason why car AC not blowing cold air after recharge.

How long until AC works after recharge?

Normally, freon takes a 15 to 30 minutes to settle in an air conditioner. But as a good rule of thumb it is better to wait for the maximum time to make sure “just in case.” Is freon the same as a refrigerant?

How do I know if I overcharged my car AC?

Signs & Symptoms of an Overcharged AC

  1. Inefficient Cooling. The most obvious sign of an overcharged AC system is poor cooling.
  2. Compressor Noise.
  3. High Pressure Readings.
  4. Struggling Engine.
  5. Broken Compressor.

Why is my car AC blowing warm air?

The most common cause of an AC system blowing warm air is a lack of refrigerant, though, you may also have a problem with your condenser. Other possibilities include a faulty compressor, broken cooling fans, or an issue in your electrical system.

Why is my car AC cool but not cold?

The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.

Why is my AC not as cold as it used to be?

If your central AC is not blowing cold air, the refrigerant may be the problem. The unit could be running low and need additional refrigerant added. The most likely cause of this is a leak. If you suspect a refrigerant leak, you should contact an HVAC professional right away.

What happens if you overcharge AC in car?

Overcharged car ac can lead to some pretty serious repairs down the road if left alone. Additionally this can actually cause your whole ac system to fail as it can also damage the ac condenser. While this is uncommon it does happen. The condenser takes the refrigerant in it’s gas form and pulls the heat away from it.

How long does it take to recharge freon in car?

How long does an air con recharge take? The process take about 45 minutes to completely remove the old gas and refill with fresh refrigerant.

What happens if you put too much Freon in a car?

Rough Idle or Stalling on a Car The air compressor for the A/C unit may not operate correctly when the system is overfilled with refrigerant. This can actually cause the car itself to run roughly or even die in some cases.

Does freon go in high or low?

The freon is added on the LOW PRESSURE SIDE ONLY. The hose tool you bought is made so you can only hook to the low side as the high side and low side fittings are different sizes and shapes for SAFETY’S SAKE.

Will too much Freon cause AC to freeze up?

No. It would actually raise the head pressure, which in turn raises the suction pressure, and the suction pressure is what will cause the unit’s evaporator coil’s temperature to drop below freezing.

How do I know if my car AC compressor is bad?

What Are the Signs and Symptoms of a Bad A/C Compressor?

  1. A Lack of Hot Air Being Released Outside.
  2. Loud or Strange Noises From the Unit.
  3. Failure of the Compressor to Turn On.
  4. Circuit Breaker Tripping.
  5. Leaks Around the Air Conditioning Unit.
  6. Warm Air Instead of Cool Air Being Delivered to the House.
  7. Reduced Airflow.

Why does my car AC not work when it’s hot outside?

The hotter it is outside, the harder the air conditioning in your vehicle has to work. Rising outside temperatures put extra strain on your entire vehicle and its cooling system, from the battery and belts to hoses and fluids, requiring each part to work overtime to keep your vehicle cool.

Recharged Car AC still warm

Your car’s air conditioning system may be running short on refrigerant if it isn’t pumping cool air. In the majority of circumstances, you can recharge your car’s air conditioning system yourself using a can of refrigerant, a charging line, and a gauge that can be purchased at any auto parts store. But what if you’ve followed the instructions on the refrigerant container and your car’s air conditioning is still not working properly? Take a look at some of the most prevalent do it yourself blunders, as well as other probable reasons, to see what you can learn.

Overcharging car AC is the most common mistake

DIYers believe that increasing the amount of refrigerant in their system will cause it to pump out cooler air. WRONG. In any case, whether the system is undercharged or overcharged, the refrigerant R-134a is not particularly forgiving. It has been shown that even a little increase in capacity of 2-ounces may reduce cooling by over 50%. Installed on the low pressure pipe, these DIY kits indicate that refrigerant be added until the dial gauge needle reaches the green zone. Charging an air conditioning system in a car is never an accurate approach to ensure that the system receives the proper charge.

The technician would attach a gauge to both the high and low pressure lines and take measurements of the shop temperature, outlet temperature, as well as the temperatures entering and exiting the evaporator, among other things.

However, the only method to ensure an exact charge is to completely drain the system and then add refrigerant by weight to the remaining space.

Close, but not quite right.

Adding too much oil is the second most common mistake

Oil is required by automobile air conditioning systems in order to keep the compressor oiled. PAG-46 AC compressor oil is a high-performance lubricant. When there is a leak in the system, oil and refrigerant are both released into the atmosphere. As a result, when you recharge your car’s air conditioning, you must pour oil back into the system. But how much do you want to put in? That is the crux of the problem. You’re completely clueless. If you use too much oil, the cooling will be reduced.

Every automobile manufacturer requires a different viscosity for the vehicle’s air conditioning oil.

That’s another area where do-it-yourselfers might get themselves into difficulty. There is no specific automotive air conditioning oil that is effective in all vehicles. If you have just purchased a can of pressurized automobile air conditioning oil, you may be causing damage to the system.

Jumpering across the low pressure switch is another HUGE mistake

Turn on the air conditioning and double check that the compressor is rotating before adding refrigerant, according to the instructions on most automobile AC recharge kits. However, if your system is so low on Freon that the compressor is unable to start, jumping the low pressure switch can cause the compressor to fail. The reason behind this is as follows. Freon (refrigerant) is responsible for transporting automotive air conditioning oil throughout the system. If your system is running low on refrigerant, it’s likely that it’s also running low on oil.

However, the refrigerant is running low on oil.

There are rare instances in which a breakdown might be so severe that it sends shrapnel across the system as a result.

Recharged car AC still warm

Okay, we’ve gone through some of the things you may do poorly that can result in difficulties. But what if you have correctly recharged your car’s air conditioning system, but it is still blowing warm air or only operating portion of the time? See these other articles for information on how to test for and address such issues. The air conditioning in the car first blows cold, then it blows warm. Even after being recharged, the car’s air conditioning is still warm. A/C in the car blows cold at highway speeds, yet warm at stoplight speeds.

Here is Why Car AC NOT Blowing Cold Air after Recharge

Tsukasa Azuma is the author of this piece. Comments were last updated on December 5, 20210. It’s a horror to discover that your car’s air conditioning isn’t blowing cold air during a scorching summer. However, this is a problem that most individuals confront. All of the numerous components in your automobile work together to provide overall functionality. As a result, even if you have recharged the air conditioning in your vehicle, the problem with the other auto equipment may still impair its operation.

So, let’s have a look at some of the reasons behind this today!

Why your Car AC not Blowing Cold Air after Recharge?

There might be a variety of factors contributing to the ineffective operation of your air conditioner after it has been recharged. You can take control of the issue if you identify the most prevalent causes of it as soon as possible!

1. The Compressor is Unable to Connect

There are a variety of reasons why the compressor may be unable to communicate with the vehicle’s air conditioning. It might be caused by an electrical breakdown in the circuit when charging, an overheated car, or simply a lack of coolant. In today’s world, the most advanced technology is capable of sensing any type of malfunction in a vehicle.

And, when it detects a problem, the air conditioning is the first item to be turned off. As a result, make sure to inspect the compressor, as it may be the source of the problem with the car air conditioning not blowing cold air after being recharged.

2. StuckBlend Air Door

The blend air door is responsible for transferring heated air to cold air in your vehicle’s system. The location of this door is in the ventilation system. If the mix door is not functioning correctly, the hot air is blasted directly from the engine. Consequently, you must take your automobile to a repair anytime you notice any problem with the jammed blend door, no matter how little.

3. Leaking Coolant

The latest generation of automobile systems is more sensitive than prior models. The chemical Freon, or simply coolant, is responsible for the rapid cooling of heated air by the air conditioning system. If there is a leak in the air conditioning system, the chemical may run out. As a result, the air conditioning would not function since there is no Freon in the system. You can deal with this scenario if you follow the finest maintenance advice. Make use of a charging machine that will pump coolant into your system and allow your air conditioner to function correctly.

4. Some other Issues

If you are unable to identify any of the concerns listed above, the likelihood is that your vehicle is experiencing another issue. The incorrect or non-operational operation of an air conditioner might indicate the presence of a major problem. While certain significant difficulties may be resolved by using do-it-yourself methods, it is best to have a technician address the interior mechanical concerns because they are more complicated. How to fix the problem of the car aircon not blowing cold air after it has been recharged.

Alternatively, you can just take your car to an expert who will know precisely what to do with it.

4 Reasons Your Car A/C May Be Blowing Hot Air

You’ve finally made it through the long winter months! Summer is almost around the corner, and it is the ideal time of year to be on the road. Even your regular commute becomes a little bit more pleasant when the weather is nice and bright. Nothing, however, can ruin a summer’s worth of pleasure quite like a broken automobile air conditioner. The air conditioning system in your car is one of the most complicated components. There might be a number of reasons why your air conditioner is spewing warm air.

1. Refrigerant Leak

A refrigerant leak in a car’s air conditioning system is frequently the cause of hot air being blown out of the vents. In your car’s air conditioning system, refrigerant flows through the system, expanding and contracting as it removes heat and humidity from the cabin. There will be no appropriate operation of the other A/C components if the refrigerant levels are not properly maintained. A leaking hose, as well as a rusty or perforated evaporator, might all be the result of age and neglect. However, don’t expect to be able to detect a refrigerant leak immediately.

This is due to the fact that, unlike motor oil and other critical automobile fluids, antifreeze evaporates when exposed to the elements.

In order to clearly detect a refrigerant leak, one of our skilled experts must inject dye into the system in order to track the leak. Once they have determined the cause of the leak, they will repair and recharge your vehicle’s air conditioning system so that it can once again blow fresh, cool air.

2. Faulty Condenser

When your A/C system removes the heat and humidity from your cabin, the refrigerant absorbs the heat and humidity from the air. The condenser, on the other hand, is responsible for keeping the refrigerant cold so that the cycle may continue. When the condenser fails to perform its function, the process comes to a halt. An arc of hot air is sprayed directly into your face at that point. The condenser is located in the front of the automobile, between the grate and the radiator, on the left side of the engine.

If the condenser is obstructed or clogged by road debris, air will not be able to reach it, and the refrigerant will not be able to cool as effectively.

If your automobile A/C troubles began after a collision or bumper bump, it’s possible that your condenser was damaged as a result of the collision or bumper bump.

3. Broken Compressor

The compressor is the core of your vehicle’s air conditioning system. It is in charge of pumping the refrigerant through the system and back out again. If this component is not functioning properly, the antifreeze will not be able to reach the condenser for cooling purposes. After prolonged periods of inactivity, such as extended winters when central air conditioning is not required, compressor problems are more likely to occur. However, many contemporary vehicles keep the condenser running all year round by activating it under the defrost option.

4. Problems with the Electrical System

Despite the fact that all of the A/C components are in proper operating condition, your automobile may be spewing hot air due to an electrical problem. A frayed wire or a blown fuse might cause an otherwise healthy air conditioner to fail to perform. The first step in diagnosing and resolving an electrical problem is to conduct a thorough visual check of your car’s fuse box and wiring. If any of these problems are causing your automobile to spew hot air, take it to your nearest Tires Plus for repair or replacement.

We’ll explain what has to be done right now and what can wait, and then it’s up to you to decide.

A/C not blowing cold after recharge, what to do?

I had the air conditioner refilled, but it is still spewing warm air. The shop replenished the gas and inserted a die into the system to check for leakage, which they found. They determined that there was no leak and that there was some gas in the system, so they simply topped off the gas supply. They also advise bringing it back if the air is not blowing chilly enough. Why isn’t the wind blowing cold? Is the gas starting to escape already? If they are unable to locate a breach, how is it possible that it will seep out in two weeks?

  1. I’ll have to spend 130 bucks to have it re-filled.

For clarification, was it ‘blowing cold’ immediately after this business refilled the gas and installed a die within the system to check for leaks and other problems?

cheapmeisterwrote:↑ Is the gas starting to escape already?

What happens if I take it back to the shop and the gas leaks out?

When the compressor kicks in, I can see the fan behind the evaporator turn on, and I can hear it kick in as well.

Does this imply that there is a good chance that the gas is seeping somewhere?

Because the business instructed customers to ‘return it back if it is not blowing cold.’ I’d just take it back to them and have them re-diagnose it and provide you answers to all of your questions at that point.

It’s more acceptable that you direct these inquiries at the firm that just completed work on your air conditioning system less than two weeks ago.

It appears that they were aware of this, since they instructed you to return it if it did not work.

The second possibility is that the compressor clutch is malfunctioning.

The radiator almost never has anything to do with the air conditioning.

The only time they come near to mixing is when they reach the condenser, and even then they do not mix well together.

August 6, 2011 at 10:31 a.m.

As Mas mentioned above, if it functioned when you went out of the store, I believe it will fail 2 weeks later.

Most likely, the shop does not appear to be qualified to adequately inspect a leak.

They had an electrical detector that could identify if the car had a charge in it if it was near the sign.

It appears that they have not followed the appropriate procedures.

After you have recovered all of the refrigerant, fill the system with nitrogen at a higher pressure and let it for a time to check if it leaks (it will), then patch the leak, purge the system/clean the system, and charge the system.

It’s possible that it’s been damaged.

After the replacement of the radiator, the air conditioning is restored.

Are you referring to a condenser?

A similar incident happened to me; after a lengthy drive to Northern Quebec, I experienced a few perforated patches on my radiator, which resulted in my air conditioner running at its maximum level.

You recently had your air conditioning evaporator replaced.

The engine radiator, on the other hand, has nothing to do with A/C.

And, if so, how long did it take you to realize that it was no longer running as cold?

If the automobile leaves the shop with the A/C still not working, the owner should take it to a mechanic who is experienced in this type of repair.

It is neither the radiator or the coolant that is the problem.

  • This might also be caused by an issue with the cooling fan, which is not operating correctly.

A new evaporator for your air conditioning system was installed by your contractor.

Nonetheless, there is no connection between the engine radiator and A/C.

It is necessary to take the vehicle to a professional if the A/C is still not working after it has been returned from the shop.

Neither the radiator nor its coolant is the source of the problem.

Your Car’s AC System Explained

Compressor: A compressor is a device that takes a gaseous refrigerant at a low pressure and low temperature and compresses it into a high-pressure, high-temperature gas, as its name indicates.

Condenser

The compressor takes low-pressure, low-temperature refrigerant while it is in a gaseous form and, as its name indicates, compresses it into a high-pressure, high-temperature gaseous condition.

Receiver/Dryer

As a result of the refrigerant being in a liquid form, the receiver/dryer is in responsibility of eliminating moisture from the refrigerant. This is accomplished by passing the water through desiccants, which are substances that absorb moisture. If you’ve ever discovered a little packet in a bottle of medication or a new pair of shoes, it’s the same substance as the one described above. The reason moisture must be removed from the refrigerant is to prevent it from freezing, which might cause the expansion valve to get clogged with debris.

Expansion Valve/Orifice Tube

As a result of the refrigerant being in a liquid form, the receiver/dryer is in responsibility of eliminating moisture from it. It does this by passing it through desiccants, which are substances that absorb moisture. If you’ve ever discovered a little packet in a bottle of medication or a new pair of shoes, it’s the same substance as the one described here. The reason moisture must be removed from the refrigerant is to prevent it from freezing, which might cause the expansion valve to become clogged with ice.

Evaporator

The receiver/dryer is in responsibility of eliminating moisture from the refrigerant, which is now in a liquid condition, after it has been cooled. Deiccants, which are substances that absorb moisture, are used to do this. If you’ve ever discovered a little packet in a pharmaceutical bottle or a new pair of shoes, it’s the same substance. The reason moisture must be removed from the refrigerant is to prevent it from freezing, which can cause the expansion valve to get clogged with debris. In comparison, water has a freezing point of -32 degrees, whereas refrigerant has a freezing point of up to -200 degrees.

5 Reasons Your AC Is Blowing Hot Air And How To Fix Them

Given that refrigerant is continuously recycled, the only time you should ever have to recharge it is if there is a leak anywhere in the system, which is quite unlikely. The first indicator of a leak is when your air conditioner begins to pump warm air. Unfortunately, pinpointing the exact location of the leak can be tricky. Why? Because once it enters a low-pressure region, such as a leak, it reverts to a gaseous condition, causing it to explode. When it comes to dealing with an AC leak, you have two alternatives.

According to the severity of the problem, this might cost anywhere from $225 to $1600 to resolve.

The second alternative is to use an AC leak sealer; however, bear in mind that these devices are designed to be used on little leaks only, not large ones.

The first type of seal conditioner causes the seals to enlarge as a result of the conditioning.

Both of these items are available for purchase in canisters ranging from $25 to $50. The nozzle on the majority of them is directly connected to the high-pressure port. Whatever you do, make sure you follow the product’s directions to the letter, every time.

The Condenser Is Malfunctioning

According to what you may recall from previously, the condenser is responsible for extracting heat from the refrigerant and then expelling it externally. If your vehicle’s air conditioning system fails for whatever reason, it will spew heated air. Due to the fact that the condenser is located behind the front grille, it is conceivable that road debris has produced a blockage or has pierced one of the interior lines. While it is feasible to remove a clog, it is not always viable to fix it, which means that you will have to replace it.

Issues In The Electrical System

If your air conditioner is producing hot air, the last thing you want is for it to be caused by an electrical problem. Why? Because locating the source of the problem might be difficult due to the fact that many of the cables are not visible without disassembling the system. Many of the AC components require power to work properly; if they are not receiving any, your air conditioning system will most likely become overheated. It is possible that you may be able to repair any frayed or broken wires with electrical tape, but it is recommended that you seek the assistance of a qualified specialist.

Problems With The Cooling Fans

As previously mentioned, the condenser is also equipped with a pair of cooling fans that assist in reducing the heat generated by the refrigerant while it is in the lines. If any of these components are damaged or malfunctioning, the air conditioning system will not perform as intended. There are a variety of reasons why they can cease working, including a blown fuse or a problem with the electrical system itself. Because they are located towards the front of the vehicle, they may potentially sustain damage from road debris.

It is expected that you will pay between $300 and $500 to replace them.

The Compressor Is Faulty

It all starts with the compressor, and as you may have imagined, if it isn’t operating properly, the rest of the system will be affected as well, if not completely. Why? Because it is the compressor that initiates the movement of the refrigerant in the first place. What causes air conditioning compressors to fail? One of the most prominent reasons for this is a lack of activity. When you turn on your air conditioner after a lengthy amount of time without using it, it might shock the system, causing it to wear out more quickly than typical.

Because of the large number of moving components in the compressor, it is nearly always preferable to replace it rather than fix it.

Fortunately, increasing the frequency with which you use your air conditioner can help to extend its life.

Why Does Your Car AC Blow Hot Air?

This is due to the fact that something within is not operating properly and requires your attention. Fortunately, if you have made it this far, you should have a lot better understanding of what is going on.

The longer you wait to address the problem, the more probable it is that it may escalate into something more serious. Regardless, can you truly survive in a hot climate if your air conditioning system isn’t working? In the end, it’s not worth it.

Why Does My Car Air Conditioner Blow Cold Then Warm?

On a hot summer day, there’s nothing quite like turning up the air conditioning in your automobile to keep cool. There are few things that feel better than a refreshing burst of air! But what if your car’s air conditioner alternates between blowing cold and warm air? If you get the impression that your air conditioner is playing tricks on you and isn’t blowing cold air for an extended period of time, it may be time to bring your A/C troubles to your nearest Firestone Complete Auto Care. There are a variety of factors that might be causing your car’s air conditioning to blast cold air first and then warm air second, including:

A Leak in the A/C System

The most typical reason for a car’s air conditioning to progressively lose its cool is a little refrigerant leak. Moisture and refrigerant combine to form a corrosive acid that eats away at the seals, valves, and rubber hoses in the air conditioning system. This is the most common source of leaks in air conditioning systems. Because there isn’t enough refrigerant in the system to cool things down, a leak in your A/C system might be causing the unit to blow warm air instead of chilly air. Worse still, the acid can corrode the interior of your compressor, causing metal shards to spread throughout your A/C system and resulting in extensive damage, obstruction, and component failure.

A Faulty Compressor Clutch

The most typical reason for a car’s air conditioning to progressively lose its cool is a little refrigerant leak of unknown origin. Moisture and refrigerant combine to form a corrosive acid that eats away at the seals, valves, and rubber hoses in the air conditioning system; this is the most common source of leaks in this system. Because there isn’t enough refrigerant in the system to chill things down, a leak in your A/C system might be causing the machine to spew warm air. Worse worse, the acid can corrode the interior of your compressor, causing metal shards to spread throughout your A/C system and resulting in extensive damage, obstruction, and component failure.

A Failing Expansion Valve

If your air conditioner alternates between being hot and being chilly, it is possible that your expansion valve is failing. During the evaporation process, the expansion valve relieves pressure from liquid refrigerant, which allows it to expand from a liquid to a vapor state. It is possible that the refrigerant flow will be restricted or too unconstrained if the valve is obstructed. A little obstruction in refrigerant flow might cause a mechanical part or piece of equipment to become very cold.

  1. The accumulation of frost or ice inside the system might make the operation even more difficult.
  2. Your air conditioner is blowing warm air.
  3. Contrary to popular belief, allowing too much refrigerant to flow into the evaporator does not result in colder air being produced.
  4. During the course of the system’s attempts to regulate the expansion valve or to cycle the compressor, the flow rate of the refrigerant might return to normal, at which point you may observe that the air temperature begins to fall once more.

Note any pools of water under your vehicle – this might indicate a freezing issue and can assist your technician in diagnosing the problem.

A Blown Fuse or Electrical Issue

The air conditioning system in your automobile is comprised of a maze of wires, switches, relays, and fuses. The electricity delivered to the A/C unit by these sections and parts under normal working conditions allows you to have cool air delivered on demand. If even one of these components fails, your air conditioner may shut down and begin spewing heated air. While this helps to avoid potentially deadly electrical fires, it also means that a simple, single blown fuse might force your entire air conditioning system to go off.

Help Us Diagnose Your Car’s A/C Problem

Take note of the following to assist our professionals in determining the source of the problem that is causing your A/C to blow cold then warm:

  • Is it all of the vents that are getting hot, or just one? How long had you been driving before the air conditioning began to blast warm air? Is this something that has happened previously, and if yes, how many times has it happened? What kind of driving circumstances are you in
  • Is it normal for the air conditioning to start spewing warm air when driving down the highway? When you’re stuck in stop-and-go traffic

When your car’s air conditioning blows cold first, then warm, take it to your local Firestone Complete Auto Care. AnA/C performance checkis the quickest and most straightforward method of determining what is wrong with your car’s air conditioner.

Why is My Car’s A/C Blowing Hot Air Out of The Vent?

In order to keep you comfortable on a hot day, your car’s air conditioning system is intended to cool down the air in the cabin of the vehicle. It’s something we frequently take for granted until it’s a hot day and your car’s air conditioning isn’t working properly. The fact that you are only getting hot air instead of cold air may be immensely annoying and unbearably painful. Getting your air conditioner checked as soon as possible is critical if your vehicle’s air conditioner is blowing warm air.

Our goal in this post is to provide you with a better understanding of how the A/C in your car generates cold air so that you can identify the problem more precisely.

How Does a Car’s A/C Work?

The air conditioning system in your automobile functions in a somewhat different manner than you may expect. Instead of really making cold air, it works by removing heat and moisture from the air in your automobile, resulting in air that feels cooler to the touch. In technical words, the cool air is produced by blowing air from either the outside of your automobile or from within the cabin over cold coils that are located inside the car. This cools the air before it is blasted into your automobile through the ventilation system, allowing you to remain comfortable while driving.

  • The actual cooling of the air takes place in these cooling coils, which are referred to as the evaporator.
  • Most modern automobiles employ a refrigerant known as R-134a, which is a particular refrigerant that is engineered to operate at the temperatures and pressures found in an automobile’s air conditioning system.
  • In order for your air conditioning system to continue operating, the warmer refrigerant must now be cooled down again.
  • The condenser is used to cool down the heated refrigerant after it has passed through the compressor.
  • In most automobiles, the condenser is located in front of the radiator and is cooled first in order to ensure that your air conditioning system delivers consistently cool air throughout the vehicle.
  • When it comes down to it, the expansion valve is a straightforward mechanism that takes use of the fact that rapidly expanding liquids and gases become cold.
  • Now that the refrigerant is cold and low-pressure, it may return to the evaporator to chill it and, with it, more air, which will help to keep your automobile comfortable.

The dryer is where any moisture in the refrigerant is removed, where the refrigerant is filtered to ensure that it all reaches the compressor as a gas, and where the oil for the system is evenly dispersed across the refrigerant going through it.

Common A/C ProblemsHow to Fix Them

Your car’s air conditioner is not operating correctly and is blowing hot air, which indicates that one of these systems is not performing its functions effectively. The process of identifying and resolving the most frequent A/C problems may be time-consuming and labor-intensive; however, we have made it easier by providing you with a list of the most common A/C difficulties, as well as information on how to fix these problems after they have been identified.

The Evaporator or Condenser is Clogged

Because there are two components that require air to be moving through them, the evaporator and the condenser, it is conceivable that one or both of these components are blocked and are not receiving the required air flow to function properly. Check for debris in the front of your car, the engine cooling fans to ensure they are operating properly, and the cabin air filter to ensure it is free of debris and grime. It is also necessary for the refrigerant in your system to be able to flow correctly through the system.

Pressures surrounding the system, both before and after the compressor, and all of the other components may be examined to ensure that all of these conditions are met.

A clog in a particular component is likely to be present if you see abnormally high pressures prior to that component and surprisingly low pressures once it is discovered.

A new air conditioning compressor may be required if you do not have a sufficient pressure rise throughout your compressor.

Electrical System Issues

Because there are two components that require air to be moving through them, the evaporator and the condenser, it is conceivable that one or both of these components are blocked and are not receiving the required air flow to operate properly. Check for debris in the front of your car, the engine cooling fans to ensure they are operating properly, and the cabin air filter to ensure it is not clogged with debris or dirt, etc. Your refrigeration system must also be able to circulate refrigerant adequately throughout it.

Pressures surrounding the system, both before and after the compressor, and all other components may be examined to ensure that they are within acceptable limits.

A clog in a particular component is likely to be present if you see abnormally high pressures before to that component and surprisingly low pressures once it is detected.

A new air conditioning compressor may be required if you do not have a sufficient pressure rise across your unit. A low refrigerant level may be to blame if you experience lower than expected pressures on the low pressure side of your system.

The A/C System Needs Recharging

The compressor in your car’s A/C system may not be able to elevate the system pressure to a level that allows the expansion valve to be efficient in cooling down the refrigerant if there is not enough refrigerant in the system to begin with. In your air conditioning system, due to the high pressures and the volatile nature of the R-134a refrigerant that is being used, it is not unusual for some of the refrigerant to leak out over time, resulting in a low pressure condition in your system. If you discover that this is the cause of your automobile air conditioner spewing hot air, you can fix it.

This time of year means that the temperature outside your car is scorching hot, and your car’s air conditioner is running at maximum capacity inside your car. And it’s likely that when you need your automobile air conditioning the most, it will fail on you and begin blowing chilly or even warm air instead. So, what is causing your car’s air conditioner to be so warm? This is something we see a lot at AutoAid. And what we discover is that the causes for your air conditioner generating pleasantly chilly or warm air might be anything from basic to sophisticated, as well as inexpensive to expensive.

Whatever the cause, AutoAid’s ASE certified mechanics can identify the issue and resolve it as quickly as possible for you.

Freon Leak

Known as Freon, this chemical refrigerant is responsible for cooling the heated air before it is pushed back into your vehicle. Because today’s air conditioning systems may be quite delicate and require a certain quantity of freon to function properly, a leak in the system can be a major problem. The leak might be caused by a broken hose, a loosened gasket, or even a faulty connection itself. In order to correct this, we must first identify the faulty components, repair or replace them, and then recharge the system with Freon.

Your Air Conditioning Needs A Recharging

Even the most efficient air conditioners can lose a small amount of refrigerant over the course of many years, often at such a sluggish rate that the user is unaware of the loss. And you may never notice that there is more than a degree or two of difference between the current A/C low temperature in your automobile and the previous one. If, on the other hand, you find that your car’s air conditioning isn’t working properly, it’s possible that you’re low on freon. As a matter of fact, it is one of the most common reasons why your car’s air conditioning does not operate at optimal temperatures.

It’s simple for us to identify whether your air conditioning system is leaking. Bring the vehicle in and we’ll perform some diagnostics on it. If it is determined that your refrigerant level is low, we may replenish your air conditioning system.

Your Blend Air Door is Stuck

While heating your automobile, warm air that travels over the engine is drawn inside the vehicle. When you turn on your car’s air conditioning and try to cool it down, a device known as a ‘blend air door’ swings across your ventilation system, closing off the warm air that is flowing into your car and allowing the cold air from the A/C system to blow in. You may have a snag in the mix air door, and when this occurs, you will continue to get warm air, regardless of how well the rest of your car’s A/C system is functioning.

The A/C Compressor Doesn’t Engage

The compressor, which is responsible for compressing the freon, is at the core of every air conditioning system. When the freon grows later on, it becomes very frigid. When air is blasted across metal that has been filled with cold freon, the air cools swiftly. If your compressor is not operating properly, the air will not get chilly. A low freon level, an electrical fault, or an overheated engine might all be contributing factors to your compressor not operating.

Blocked or Broken Condenser

Condensers are responsible for converting freon gases back into liquid form. If the condenser is clogged with dirt or broken, the refrigerant will not be able to pass through. This means that you will not receive any chilly or even cool air from our air conditioner during this time.

Electrical Problems

Another possibility is that there is a very simple explanation for your automobile air conditioning not to be working, and that the problem is electrical in nature. Some of the components of your air conditioning system, including the compressor, are powered by electricity. A blown fuse, for example, might cause it to stop operating completely and without any warning. When you live in Los Angeles, where temperatures may approach summer levels virtually any time of the year, it’s critical that your car’s air conditioning be operational at all times.

Our experts can do a complete diagnostic test on your vehicle and tell you exactly what is wrong with your air conditioning.

Nonetheless, in case the issue is more serious, it’s comforting to know that our ASE Certified Mechanics are on hand to properly diagnose and service your air conditioning system.

6 Reasons Why Your Car Air Conditioner is Not Blowing Cold Air

The sheer thought of driving a car with a faulty air conditioner is enough to make you feel nauseous and uncomfortable. It is not enjoyable to be driving in your vehicle on a hot summer day (with the normal high temperatures observed here in Dubai, UAE) while the car air conditioning is not functioning. While air conditioning provides welcome reprieve from the sweltering heat, it also poses a threat to public health and safety.

It is possible to suffer major health consequences from driving in the heat and with a faulty air conditioning system, including pain, disorientation, and the possibility of heatstroke.

Reasons why your car ac is not blowing cold air

The most typical cause for your car’s air conditioner to blast hot air is either a broken compressor or a coolant leak, both of which are common problems. Among the several automotive air conditioning difficulties are a fully nonfunctional air conditioner, hot air blowing from it, and your air conditioner blowing cool air instead of maintaining correct cold temperature levels. As a result of the usual expectation of experiencing chilly air when turning on your air conditioner, it’s understandable to be confused when you’re met with warm air instead of cool.

If your air conditioning is not operating properly, or if you are not getting enough cold air, it might be due to a general repair or service required for the numerous components that make up your vehicle’s cooling mechanism.

Here are 6 reasons to help identify why your air conditioner is not working properly

It’s possible that your air conditioner isn’t blowing cool air because it’s running short on battery power. This is the most typical reason for a car air conditioner to fail out of all the other reasons that might occur. It’s possible that a low charge in the air conditioner is causing insufficient cooling, and the only solution to cure the problem is to recharge the air conditioner completely. You may either recharge the refrigerant yourself or hire a professional to take care of the service aspect.

2. Refrigerant Leakage

Another possibility for why your air conditioner isn’t blowing chilly air is that it’s leaking refrigerant. When there is insufficient pressure in the system, the compressor will not be able to cycle properly, resulting in the production of hot air. The refrigerant leakage can occur at any point along the hose connections of the A/C unit, therefore while checking for it, look for any probable oily material accumulation and seal it using the sealant recommended by your A/C manufacturer (the ones specially designed for air conditioning units).

  1. In the event of a significant leak, you may be required to clean out the whole refrigerant system and correctly replenish the fluid.
  2. Your car’s condenser serves as both an evaporator and condenser.
  3. After a period of time, dust and grime might build, which can cause the pipe to get clogged.
  4. This is normal.

4. AC Compressor Failure

Before it reaches the condenser, the refrigerant is compressed by the automotive air conditioner compressor, which creates tremendous pressure. With a malfunctioning compressor, your vehicle’s air conditioning system will not perform at its best. If the compressor is left idle for an extended amount of time, it will require maintenance.

Another possible cause of its malfunction is an electrical problem in the circuit or clutch, or it might be leaking refrigerant, among other things. When it comes to auto air conditioning repairs, only certified mechanics should be used.

5. Cabin Filter Damage

The automobile cabin filter’s primary role is to remove dust particles that enter the vehicle from the front end while driving. A malfunctioning air cabin filter will insufficiently filter out the debris that enters into the vehicle, and the accumulation of debris might cause damage to the motor fans and the vehicle’s air conditioning condenser. 6. Motor Fans are a source of damage. Over time, debris accumulation on the motor fans may cause damage to the motor, which in turn prevents cold air from reaching the condenser, resulting in you receiving warm air even when the air conditioning is turned on.

7. Condenser Damage

A similar situation occurs when you feel hot air coming from your car’s air conditioning system, but the problem is caused by other parts failing. Rather of clogging your car’s air conditioning condenser, debris and dirt from the road may cause harm to it or even cause it to completely fail. You may physically inspect the front of your automobile condenser to see whether it has been obstructed or damaged by road debris to determine whether this is the case.

8. Condenser Fan Failure

Alternatively, the failure of the fan motors in the vehicle might be the cause of the necessity for auto ac repair services. You can physically check the damaged fan in the system if it is located therein. Because of the faulty fans, your car’s air conditioning condenser will not receive proper cooling, and as time passes, you will begin to experience heated air instead of cold air. Depending on the circumstances, the fan might be damaged due to dust and dirt collection, a blown fuse, or other electrical difficulties with the machine.

You should seek expert assistance if you are unfamiliar with the technical aspects of automobile air conditioning repair.

Cost of Car AC Repair in Dubai

Normal automobile air conditioning servicing prices might range up to 300 AED and can vary depending on the car service shop you choose. Checking the compressor, wiring, hose connections, and condenser may result in an increase in the cost of auto air conditioning repair. The cost of automobile air conditioning repair will vary depending on the model and kind of car, as well as the work that is necessary (specific details or overall check for ac failure). The most likely cause of your car’s inability to blast cold air is a lack of routine maintenance.

Why is My Car’s Air Conditioning Blowing Warm Air?

When it’s operating properly, your air conditioner is fantastic. In the absence of a working air conditioner, traveling in your automobile can be difficult, particularly on hot summer days. If your air conditioner is blowing warm or even hot air, there are a few possibilities as to why this can be happening. Here are a few of the most often cited reasons. Problems with the electrical system First and foremost, it is possible that your electrical system is experiencing difficulties. The cabling, switches, fuses, relays, and other components of the electrical system are responsible for delivering electricity to the air conditioning unit and are intended to shut down if even a single component fails.

Fortunately, this is rare.

Change The Cabin Air Filter is an important piece of equipment.

Cabin air filters are capable of capturing dust, bugs, leaves, and a variety of other forms of material.

Failure of the compressor It is also possible that your compressor has failed, which is a typical occurrence.

Because it is one of the most critical components of an air conditioning unit, a compressor failure can result in the complete failure of the system.

If you have a leak in your system, it might be causing your unit to blast warm air since there isn’t enough refrigerant in the system to cool things down.

The pros at your local auto shop utilize sophisticated gear, like as ultraviolet detectors, to determine whether or not your system has developed a leak.

As a result, because the condenser is placed nearer to the front of the car, it is more susceptible to damage from road debris such as fallen leaves or plastic bags, as well as pebbles and sticks, which can create punctures.

However, if it fails to do so, or if it does so inefficiently, the refrigerant will remain warm and will be unable to chill the air beyond the temperature of the surrounding environment.

Whenever this condenser malfunctions or is somehow compromised, your air conditioner will produce heated air. To get assistance in staying cool and comfortable this summer, schedule an appointment to have your car evaluated by one of our experienced air conditioning technicians.
