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 AC blowing warm air?
Your air conditioner’s evaporator coils extract heat from the home’s air to start the cooling process. When moisture collects on the evaporator coils, they may freeze. Frozen coils prevent heat transfer, so you’ll feel warm air blowing from your AC system if this problem is present.
How do I fix my AC blowing warm air?
If your AC is blowing hot air, the thermostat may have been accidentally set to “heat.” If this is the case, it’s easy to fix on your own. Simply flip the thermostat setting back to “cool” and see if the air conditioner begins to blow cool air again.
Why is my AC running but not cooling?
Condenser Unit is Blocked If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser coil. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your home.
What does blowing hot air mean?
New Word Suggestion. A person that has a lot of verbal wind that likes to sound off.
Why would AC work but not heat?
A Faulty Thermostat Try turning on the thermostat and adjusting the temperature so that your HVAC is turned on. If it fails to come on, check the circuit breaker and ensure that the switch is functioning properly. If you find that it had tripped, turn it back on. This should fix the problem.
What happens when the temperature of air cools?
Because each molecule uses more space for motion, the air expands and becomes less dense (lighter). The opposite effect happens when air cools. As the temperature drops, molecules move more slowly, taking up less room. The amount of space the air takes up shrinks, or reduces the air pressure.
Is warm air heavy or light?
Hot air is lighter than cold air. The reason fr this is when air gets heated up it expands and becomes less dense than the air surrounding it also the distance between the molecules increases. So the less dense air floats in the much denser air just like ice floats on water as ice is less dense than water.
What does blowing hot and cold mean?

AC Blowing Hot Air: What’s Wrong? 6 Common Causes & Fixes For AC Warm Air
“When I switch on my air conditioner, it immediately begins to blow hot air. The problem of an air conditioner spewing warm air is not an unusual AC problem. AC spewing hot air, in contrast to the majority of seemingly innocuous problems, is extremely frightening. In essence, the air conditioner should be blowing chilly air. That’s pretty much what it’s there to do. When your air conditioner begins to blast hot air, you must shut it down and repair it as soon as possible. That means you must first determine why your air conditioner is spewing warm or even hot air.
If your house air conditioner is blowing warm air when the thermostat is set to chilly, it is most likely due to the following HVAC phenomenon: The coils of the cooling system are heated.
It is only through adequate compression that refrigerant can be properly expanded (and perform the endothermic process that results in the production of cold).
A schematic representation of the refrigeration cycle.
Low refrigerant levels and a broken AC compressor are two of the most prevalent reasons of an air conditioner that blows hot air.
We’ll also give you some pointers on how to fix your air conditioner that’s blowing warm air yourself (DIY) and when it’s best to call in a professional.
In other words, these causes apply to all types of air conditioners, including the following:
- It starts blowing hot air as soon as I switch on the air conditioner. A typical AC problem is that the air conditioner is delivering warm air rather than cold. Air conditioning producing hot air, in contrast to the majority of seemingly innocuous problems, may be highly dangerous. In essence, the air conditioner should be blowing cold air. In a nutshell, that is what it is responsible for. Immediately shut down and repair your air conditioner if it starts blowing hot air. In order to do so, you must first determine why your air conditioner is spewing warm or hot air. As a result of passing through cooling coils, the air that comes out of an air conditioner or indoor air handler is chilly (refrigerant coils). This is the HVAC phenomena that occurs when your home’s air conditioner blows warm air when on the chilly setting: The coils of the cooling system are quite hot! The refrigerant (R22, R410A, and so on) expansions that occur in a running air conditioner cool the cooling coils. When refrigerant is adequately compressed by an air conditioning compressor, it may properly expand (and perform the endothermic process that creates cold). The refrigeration cycle is depicted in diagram form below. Problems within this cycle are typically the cause of the AC spewing hot air. Low refrigerant levels and a broken AC compressor are the most typical reasons of an air conditioner generating hot air. It is our goal in this post to provide you with a comprehensive understanding of the six most prevalent reasons why your AC is spewing hot air instead of cool air. As well as advising on how to repair an air conditioner that is blowing warm air on your own (DIY), we will also advise on when to call a professional HVAC technician. Every air conditioner operates on the same basic premise. These factors apply to all types of air conditioners, including but not limited to:
What sort of air conditioner you have doesn’t really important; all of them make use of freon, air filters, and a compressor. It makes sense to go over all of the factors that might cause an interior air handler to blast hot air in this article. You will have a better understanding of what could be wrong with your air conditioning system. But first, let’s take a look at how an air conditioner should function. We will be better equipped to discover what is causing the AC unit to blow warm air after we have grasped this concept.
How Air Conditioner Should Work (If Cooling Coils Aren’t Hot)
Your air conditioner only blows cold air when the cooling coils are cold. Period. When an air conditioner is in proper working order, the air is forced through cooling coils. The air is cooled as a result, and we enjoy a refreshing breeze from our air conditioner. Having heated cooling coils will not provide us with a cool breeze; instead, we will get a hot AC airflow output, which no one desires.
To explain why the air conditioner is blowing hot air, we must first determine what is causing the cooling coils to get hot. It is necessary to cool down the cooling coils with the help of a mix of refrigerant and compressor. The following diagram depicts how a typical air conditioner operates.
- The refrigerant is compressed by the AC compressor, converting it from a gas to a liquid. This process is exothermic, meaning that it generates heat. All of that heat is directed outward
- The refrigerant in liquid form passes through the expansion valve and changes into gas
- This process is endothermic, which means that it pulls heat from the surrounding environment to operate. The cooling coils are in the’surrounding’ area
- This helps to cool the indoor coils down. Air is forced through these frigid cooling coils, and we are treated to a refreshing breeze from our air conditioning unit.
If your air conditioner is blowing hot air, it means that something is wrong with the operation. Either the compressor is not compressing adequately (completely), the expansion valve has failed, or there is a general deficiency of refrigerant in the system overall. Examine the following to determine what is wrong with your hot air blowing AC:
6 Common Causes Of Air Conditioner Blowing Hot Air
There are a variety of reasons why your home’s air conditioner is spewing warm air. The majority of the time, overheated cooling coils are caused by a problem with the refrigerant cycle (low freon, compressor issue, valve issue). On a less frequent basis, the reason may be of an electrical type (thermostat issues, power issued). We’ll go through each of the issues that might be causing your air conditioner to blast hot air one by one. Here is a comprehensive list of the most common reasons why your air conditioner is spewing warm air:
- For a variety of reasons, your home’s air conditioner is spewing hot air. The most typical reason for heated cooling coils is a problem with the refrigerant cycle, which may be repaired (low freon, compressor issue, valve issue). An electrical malfunction is a less common occurrence (thermostat issues, power issued). We’ll go through each of the issues that might be causing your air conditioner to blast hot air one by one in this section. The following is a comprehensive list of the most common reasons why your air conditioner is spewing warm air: 1.
Let’s start with the most common reason for your air conditioner to produce hot air:
1 Low Refrigerant Levels Are The Cause Of AC Blowing Warm Air
Begin with the most common reason of an air conditioner that blows hot air:
2 Faulty Compressor Leading To AC Blowing Hot Air
The cause of your air conditioner producing hot air might be a malfunctioning AC compressor. An AC compressor has only one job: to compress the freon. If your freon levels are normal, the problem could be a faulty AC compressor. Full expansion of fully compressed freon will occur, and the cooling coils will be completely cooled. If the air conditioning compressor does not perform as expected, and the freon is not entirely compressed, the freon expansions will be insufficient as well. It is possible that cooling coils will not be effectively cooled as a result of this.
- Compressors have a reputation for being difficult to repair.
- If you have a small window or portable air conditioner, you can try to replace the compressor yourself.
- When dealing with larger units (central air, mini-splits, and heat pumps), it is preferable to have a professional do the work.
- Once the air conditioning compressor is replaced or repaired, the freon compressor will return to normal operation.
3 Clogged Filters (Not Dirty) Can Cause AC To Start Blowing Warm Air
The air conditioner must maintain a suitable amount of airflow in order to perform correctly. If you fail to do so, you may experience hot air flowing from the air conditioner. Clogged air filters are one of the things that might drastically impede airflow if they are not cleaned regularly. If the air filters become clogged, the airflow will be dramatically decreased, and every component of the air conditioning system will attempt to adjust for the lower airflow (because its goal is to achieve a low temperature, as set by the thermostat).
Located on the capillary tube that connects the outside unit/part to the inside unit/park, the expandable valve allows for greater flow of air.
The airflow must be significantly limited in order for the air conditioner to begin blowing warm air (at a temperature greater than the inside temperature).
Air filters that are clogged and merely require cleaning are not the source of the warm air coming from your air conditioning machine.
AC filters that are clogged are a problem. In this scenario, the solution is straightforward: simply change the air filters. When the airflow returns to normal, the air conditioner will resume regular operation.
4 Clogged Expansion Valve Causes Hot Air Coming From AC
The expansion valve’s primary function is to efficiently discharge refrigerant liquid through the system and expand it into gas form. When this expansion occurs, it causes ‘chills’ to be transmitted throughout the cooling coils. That is precisely what causes the cooling coils to cool down. Due to faulty operation of the expansion valve, the amount of refrigerant that can be expanded into gas will be insufficient, and the cooling coils will not be appropriately cooled. While the air conditioner is functioning, it is possible that warm air may be blown out of it.
Cloggage.
To solve the problem, you must first unclog the pipes, which is a much simpler task said than done.
After the clog has been removed, the refrigerant cycle should be restored to normal, and the air conditioner should no longer blast warm air.
5 Power Issues: Blown Fuses And Tripped Amp Breakers
In addition to problems with the refrigerant cycle, electrical problems can also cause your air conditioner to spew heated air. The first step is rather straightforward; simply inspect all of the outlets and wires. Generally speaking, this is OK. One item we can overlook – and which could result in excessive heat emanating from your air conditioner – is blown fuses and tripped circuit breakers. To safeguard our air conditioner from electrical surges, we employ both fuses and amp breakers. If there is something wrong with them — a blown fuse or a tripped amp breaker, for example – you may be experiencing some strange consequences.
Check to see whether your air conditioner’s fuse has blown or if the amp breaker has been tripped.
6 Thermostat Issues: Wrong Setting Or Wiring Problem
It may seem obvious, but if your thermostat is set at a setting higher than the room temperature, your air conditioner will blast heated air. This is generally the first item we double- and triple-check before moving on. In the vast majority of circumstances, the thermostat setting is satisfactory. The new thermostats are causing the biggest problems. If your new air conditioner is spewing hot air, there is a possibility that the thermostat is not correctly connected. The incorrectly wired thermostat is a complete jumble; a muddle that may result in some unexpected occurrences, such as hot air entering from your air conditioning machine.
If your air conditioner was operating normally previously, it should continue to operate normally today.
For example, the possibility of a wire falling out of the thermostat socket is quite remote. This thermostat wiring guide may be used to determine whether or not your thermostat is correctly connected (blue wire or B is usually responsible for air conditioning).
Final Note
With any luck, you’ll be able to figure out what’s wrong and, in some circumstances, even remedy the problem with your air conditioner spewing hot air now. The final word is as follows: There is a distinction between an air conditioner that blows hot air and an air conditioner that does not blow cold air. If the air flowing from your air conditioner does not cool the room above the temperature of the room, you might want to read this article on why your air conditioner is not blowing cold air.

How Does An AC Work?
First and foremost, let’s go over the fundamentals: Your air conditioning system is not producing cool air. A fan pushes warm interior air through a filter and over the evaporator coil, rather than via the vent. The coil is filled with refrigerant, which is a specific chemical, and when warm air is forced over it, the heat is absorbed by the refrigerant in the cold coil, which then cools the air. The air is blasted back into the heated portions of the home, where it has become cooler. Now, if the air that is being blasted back into the home is warm, it is possible that the coil is not collecting the heat from the air for whatever reason.
This is the process by which hot gas is compressed into even hotter vapor, as the name implies.
You could be thinking at this point that this sounds complicated, and that you wonder how you could ever discover the problem with your air conditioner.
Keep in mind that you may not be able to do so, in which case you would need AC professionals such as SuperTech HVAC (if you lived in Maryland).
Seven Reasons Why YourACBlowing Hot Air
Before we get started, let us review some fundamentals: There is no cold air being produced by your AC system. To replace this process, a fan draws heated interior air through a filter and over the evaporator coil. Heat is absorbed by the refrigerant in the cold coil when warm air is forced over it, and the refrigerant in the warm coil absorbs the heat emitted by the warm air as it passes over it. The air is blasted back into the heated portions of the home, where it has now become chilly. As a result, if the air being pushed back into the home is warm, the coil is not collecting heat from the air for whatever reason.
The refrigerant is heated until it becomes gaseous, at which point it passes into the compressor.
During the third stage, which takes place within the condenser unit, the heat from the hotter vapor, which has been sent over by the compressor, is expelled outside, converting the refrigerant in the coil back into a cold liquid and resuming the cycle.
With our assistance, you have a chance, believe it or not. Keep in mind that you may not be able to do so, in which case you would need air conditioning professionals such as SuperTech HVAC & Plumbing (if you lived in Maryland). Please go through your list with me.
Is The AC Coil Frozen?
When heat is not absorbed into the coil for a specified period of time, the evaporator coil freezes. This is due to the chemical characteristics of the refrigerant. So, what is it that keeps heated air from accumulating around the coil? It appears that airflow has been interrupted in some way, which might signify one of several things:
- The air filter is clogged. The return vent is being blocked by dirt and debris, which prevents warm air from entering. OR a household object, such as a sofa or a blanket, is in the path of the vent and is preventing air passage
- The air duct has collapsed owing to wear and tear, poor installation, or pests in one of the less likely scenarios
- As a result, air from the return vent is unable to reach the coil. The evaporator coil is clogged with dirt. The evaporator coil is coated in a thick layer of filth, making it impossible for air to get through. A dirty filter or fractures or fissures in your air ducts might be the source of the problem if dirt has made its way into this region.
If your air conditioning system appears to be in good working order and clean, it is possible that your system is short on refrigerant, resulting in a frozen evaporator coil.
So, Your Ac Blowing Warm Air Could Be Due To A Refrigerant Leak.
When we placed pressure on the refrigerant, we noticed that it heats up significantly. The same holds true for the inverse situation. When the refrigerant concentrations are low, the chemical liquid in the coil expands, cooling the coil until it freezes completely. Because your air conditioner is a closed loop system, if your refrigerant level is low, it is escaping through a leak in the refrigerant line. Furthermore, after the coil has frozen over, your air conditioner will be unable to remove the heat from the air in your home.
Do not attempt to repair the freon leak on your own.
(Those of you who live in Maryland can obtain AChelp by clicking here.) Your air conditioner is not blowing cold air because the condenser coil is filthy.
Your AC Not Blowing Cold Air As A Result OfDirty Condenser Coil.
Because the box that covers the coil must convey the heat to the outside, it is equipped with a ventilation system. It can also experience significant damage as a result of being subjected to harsh weather conditions. Exposedcoils may become contaminated with dirt, trash, animals, and even grass if they are not protected from the elements. This can prevent the coil from operating normally as intended. In order to prevent your air conditioner from blowing hot air, it is critical to maintain the space surrounding the condenser box free of obstructions.
Your Compressor Might Have Failed So Your Air Conditioner Blowing Hot Air.
It functions similarly to a heart in that it pumps refrigerant throughout your HVAC system. Every cycle, low pressure gas is transformed into high pressure gas in this chamber. Because it is such a critical component of your central air conditioner, it consumes the most power when in operation. Every year, an aged compressor consumes an increasing amount of power. Eventually, the aging compressor may unintentionally trip your breaker by using too much current, resulting in your air conditioner spewing heated air.
The worst-case situation is that your compressor becomes grounded.
If this is the case, you will need to have the compressor or the complete outdoor air conditioning equipment replaced.
It might be difficult to diagnose problems with a compressor. When in doubt, the most straightforward course of action is to contact a professional – such as the experts at SuperTech HVAC – for assistance.
Or Is It Your Condenser Fan?
This fan in your outdoor unit is responsible for transferring the heat generated by the coil outdoors. Your condenser overheats if it is not spinning, and a safety device, generally a high pressure switch, shuts it off to avoid harm to your air conditioning system. When this occurs, your coil is no longer capable of collecting the warm air from your home as effectively. As a result, if your air conditioner is not blowing cold air, it is possible that your condenser fan is to blame. Probably the most likely possibility is a burned-out fan motor as a result of ordinary wear and tear.
It is also possible that the fan has been damaged.
Keep in mind that if your fan is not receiving electricity, it will not be able to turn.
Loss Of Power To Outdoor Unit Could Be The Cause Of Air Conditioner Blowing Warm Air.
On a hot day, you run the danger of blowing a fuse due to an outdated electrical system and outside air conditioning equipment. Why? Because, as previously said, an outdated air conditioning unit will struggle to satisfy your cooling requirements and will use excessive electricity to achieve its purpose. The circuit gets overloaded, and if the fuse overheats (which might happen for a variety of reasons), the circuit is shut off and the fuse replaced. Modern air conditioning systems feature a circuit panel rather than a fuse that “trips” when the circuit is overexercised.
Make sure you keep an eye on the situation, and if it occurs again, there is an internal problem that has to be addressed.
Instead, call for assistance.
It is positioned outdoors, next to the compressor, and lets you to manually turn off the electricity to your air conditioner.
Here’s How To Troubleshoot The Problem Of AC Blowing Hot Air Yourself Before You Call Us
- The fan or coil may be malfunctioning, but the entire outside unit may be out of commission. If this occurs, check to see whether the breaker has tripped and, if so, try resetting the breaker. Generally speaking, your circuit breakers are grey panels with a door that are positioned in a low-traffic section of your home, such as your basement or garage
- You can also check and re-set the disconnect box on your air conditioner (see the section above). In the event that your coil has frozen, there are a few things you may do before contacting for help: Turn off the air conditioning and use a fan to melt the ice.
- If your air conditioner’s disconnect box is not working properly (see part above), you can inspect and reset it. In the event that your coil has frozen, there are a few things you may do before contacting for assistance: To begin melting the ice, turn off the air conditioning and blow on it.
Evaporator coil that has been frozen
- Check to see if anything is obstructing air passage into your return and supply vents (furniture is the most likely problem)
Finally, contact SuperTech HVAC for air conditioner repair; alternatively, if you live outside of Maryland, contact your local HVAC specialist for assistance.

Wrong Thermostat Setting
It’s possible that you’re getting hot air because your thermostat is set to “heat,” believe it or not. Ensure that it is set to “cool” by checking it again. Also, make certain that it is set to “auto” rather than “on.” The “on” setting will cause the fan to run continually – even if your air conditioner isn’t producing any cooling. Warmer air will be forced through your vents as a result of this.
Outside Unit is Clogged
Unbelievable as it may seem, your thermostat may be set on “heat” if you are receiving hot air.
It should be set to “cool,” so double-check that. Check that the “auto” option is selected rather than “on.” While your air conditioner isn’t running, the “on” setting will make the fan run continually. Warmer air will be forced through your vents as a result of this procedure.
Outside Unit Has Lost Power
It’s possible that you’re experiencing hot air because your thermostat is set to “heat.” Check it again and make sure it is set to “cool.” Also, make certain that “auto” is selected rather than “on.” The “on” setting will cause the fan to run continually – even when your air conditioner isn’t providing coolness. As a result, warmer air will be forced through your vents.
Evaporator Coil is Dirty
It’s possible that a clogged evaporator coil is the source of your air conditioning problems. The most common reason for this is a clogged air filter. While you can replace the filter on your own, you’ll need to hire a professional to clean the evaporator coil on your air conditioner.
Refrigerant is Low
The refrigerant in your house is responsible for collecting heat from the air in your home. If it leaks, your air conditioner will have a difficult time cooling the air. If you notice ice accumulating on the outside of your interior and outdoor air conditioning systems, you have a refrigerant leak. To resolve the problem, you’ll need to add refrigerant to the system. The most effective method of preventing your air conditioner from spewing heated air is to get it serviced twice a year. Please contact us atJacksonSons.JacksonSons, Inc.

The History of Air Conditioning» «The Reason Your Thermostat Isn’t Running on Time»
Why is my AC blowing warm air?
When you are trying to stay cool on a hot day, even if your air conditioning appears to be functioning (it is blowing), it can be really aggravating. Is it just me, or is it quite warm in here? You check the thermostat and see that the temperature has risen much over the preset level. When you place your palm over one of the air conditioning registers, you will notice that the air conditioner is blowing warm air. What exactly is going on? Is it possible that your air conditioner is blowing warm air due to a minor problem that you can fix yourself, or do you need to call in a professional?
7 common causes of AC blowing warm air
Your air conditioner is spewing warm air because something is preventing the cooling system from working properly while the fan is running. Simple factors such as thermostat settings and poor air movement might contribute to the problem, but more serious concerns such as electrical faults and refrigerant leakage can also contribute to the problem.
The first step will be to identify and remedy the little difficulties that you can do yourself. The next step will be to identify and repair major problems that will require the expertise of a professional.
1. Thermostat issues
You have warm air coming out of your AC because something is disabling the cooling process even if your AC fan is running at full speed. A variety of factors, from basic items such as incorrect thermostat settings and insufficient air movement to more serious concerns such as electrical faults and refrigerant leakage, can contribute to this problem. The first step will be to identify and remedy the little difficulties that you can do yourself. The next step will be to identify and repair major problems that will require the abilities of a professional.
2. A clogged filter
Low air flow is one of the most prevalent issues that can cause your air conditioner to stop working properly and cause it to overheat. Despite the fact that it may sound strange, your air conditioner really requires warm air to pass over the coils in order to operate effectively. The filter in your air conditioner is meant to remove dust and other impurities from the air that is circulated through the unit. An air filter that has been clogged with dust and debris, on the other hand, can entirely prevent air from entering the system.
As a result, the fan on your system just pushes heat back into your area.

3. Return vents closed or blocked
Another issue with air movement that might result in your air conditioner spewing heated air is as follows: Do you think it is feasible that vent grilles were closed for the winter and then never re-opened again? Alternatively (and this is typical in workplaces!) do you have furniture or other impediments preventing them from being used? Take a tour around your area and make sure that all of the registers and returns are open and enabling air to easily flow through it.
4. Disconnected or leaky ducts
It’s also conceivable that you’re experiencing air flow issues that aren’t visible. in your ductwork. If a duct has holes, fractures, or is entirely detached, it is possible that return air is not making it back to the HVAC system. Alternatively, it is possible that cooled supply air is being wasted in your walls, attic, or crawl area, resulting in the AC blowing warm air. Checking your ducts may be worthwhile if they are easily accessible to you. It is not unusual for damage to occur during building projects, or as a result of birds or rats entering into construction sites.

5. Loss of power to the outdoor unit
It’s also conceivable that you’re experiencing air flow issues that aren’t visible. in your duct system. The return air may not be reaching the unit if a duct is obstructed by holes, cracks, or is entirely detached. The supply air may be being wasted in your walls, attic or crawl space as a result of which the air conditioner is spewing hot water. Consider inspecting your ducts if they are easily accessible. Birds or rats entering into building sites may cause significant damage, and it is not rare for this to occur.
However, on second thinking, it’s possible that it’s best to hire a professional to evaluate the quality of your ductwork in this situation. Articles that may be of interest: Having trouble with your air conditioner’s air flow? Duct problems should be investigated.
6. Dirty condenser coils
It is one of the most crucial duties of your condenser unit to remove heat from your building and discharge it to the outside environment. It is the condenser coil’s responsibility to perform this function. The fact that it is exposed to the outdoors means that it can become caked in filth and grime, not to mention leaves and rubbish. Eventually, this interferes with the working of the coils, and your system is unable to efficiently cool, resulting in the AC blowing warm air.

If you did discover a little issue that you could simply resolve, congratulations! We’re willing to bet you’re anxious to avoid anything like this happening again. Preventative air conditioning maintenance is the secret to enjoying uninterrupted comfort throughout the summer. It’s worth checking out; you’ll be pleased you did!
Why Is My Air Conditioner Blowing Warm Air?
Summer has here in full force. While summer activities such as barbecues and pool parties are enjoyable, we all rely on the warmth of our own homes to give much-needed relief from the heat. This is the time of year when we rely on our air conditioners the most. For HVAC professionals, this is also the busiest time of the year. Every single day of the summer, we receive calls about air conditioners that are spewing heated air. The good news is that it’s a frequent HVAC failure that may occasionally be fixed by the average homeowner.
Service Champions is willing to lend a hand.
Thermostat
The thermostat is the first item you should check, and it may seem apparent. But it is important to do so. If your air conditioner is producing hot air, it’s possible that the thermostat was unintentionally set to “heat.” If this is the case, it is simple to correct the situation on your own. Replace the temperature setting on the thermostat back to “cool” and observe whether or not the air conditioner begins to pump cool air again. In addition, you want to make sure that the batteries are operational and that the temperature is not set too high a degree.
The “on” setting implies that the fan will operate continuously to circulate the air, even if the air conditioner or heater is turned off.
The Solution: Check the thermostat to ensure that it is set to “cool” and that the temperature is at the right level.
During the cooling season, we recommend keeping the thermostat set at roughly 78 degrees Fahrenheit, with the temperature raised by 7-10 degrees when away from home.
It is possible to save 10% on your annual heating and cooling expenditures by using a setback period of 8 hours or more (U.S. Dept. of Energy). Is it necessary to upgrade your thermostat system? Learn how to select the most appropriate thermostat for your house.
Circuit Breaker
Although it may seem apparent, the thermostat should be the first item you check. Your air conditioner may be producing hot air if the thermostat has been mistakenly set to “heat” by mistake. If this is the case, it is simple to correct the situation on your own time and resources. Replace the temperature setting on the thermostat back to “cool” and check if the air conditioner continues to pump cool air once more. In addition, you want to make sure that the batteries are operational and that the temperature is not set too high for comfort.

The thermostat should be the first item you check, even if it may seem apparent. If your air conditioner is producing hot air, it’s possible that the thermostat has been unintentionally set to “heat.” If this is the case, the problem is simple to resolve on your own. Simply return the thermostat setting to “cool” and see whether or not the air conditioner continues to pump cool air once more.

Condenser Coils (Outdoor Unit)
If you’ve already examined the thermostat, breaker box, air filter, and inside coils, it’s time to head outside and look at the outside unit in more detail. Just as the interior evaporator coils require open airflow, the outdoor evaporator coils require the same thing. As a result, it is suggested that a 2-foot space be maintained around the outside condenser unit at all times. If your outdoor unit is clogged, switch off the unit at its source to clear the blockage. Then, using gloved hands, remove the larger pieces from the pile and rinse away the smaller waste with your garden hose.
Make a point of scheduling a professional air conditioning tune-up and cleaning at the beginning of every cooling season.
Check to be sure that your HVAC firm includes complete interior and outdoor coil cleanings as part of their monthly tune-ups and maintenance. Additionally, in addition to professional cleaning, it’s a good idea to check on the outside unit on a regular basis and clean it yourself as necessary.
Refrigerant
Low refrigerant levels are one of the most common reasons of a malfunctioning air conditioner. It is possible to have undercharged or overcharged refrigerant if you have a worn service valve, loose joints, or a defective assembly. The Solution: Refrigerant (also known as coolant) is extremely hazardous. If you are not a skilled expert, you should never attempt to repair refrigerant problems on your own time. Annual air conditioning tune-ups performed before the cooling season begins are the most effective method of preventing refrigerant leaks from occurring in the first place.
The sooner you respond to a refrigerant leak caused by under or overcharging, the better.
Important Reminder: Do not rely on a technician that just adds refrigerant to your system.
Prior to adding any refrigerant, your HVAC specialist should fix the leak in the system.
Additional Summer Air Conditioning Tips:
- Keeping your thermostat set at 78 degrees while at home and 7-10 degrees higher while away from home will help you save money. Make use of your ceiling fan to feel around 4° colder. Prevent moisture problems from occurring by providing enough ventilation. Consider enrolling in a home maintenance plan to ensure that you never miss your annual tune-up visits. Plan to check your air filter every 30 days by setting a reminder. If you’re operating the air conditioner, keep the doors and windows closed. Maintain a regular cleaning and dusting schedule in your house.

Circuit Breaker
Check the electrical panel to ensure that the HVAC system is receiving power after you have checked the thermostat batteries and setting on the thermostat. HVAC equipment consume a significant amount of electricity to operate. When there is an excessive amount of power demand, the circuit breaker may automatically shut down the electricity as a safety measure. The Solution: Locate your electrical panel and inspect it for a tripped breaker or a blown fuse, if appropriate. The unit’s power can be restored by first turning the breaker completely off (in the opposite direction of all the other breakers) and then turning it back on.
This may also be an excellent moment to name all of your circuits so that they can be quickly identified the next time a circuit is overloaded.
Evaporator Coils and Air Filter
Air filters have nothing to do with the temperature of the air, but a clogged air filter might lead to clogged coils on the evaporator coils. Because of the buildup of dust and debris on the evaporator coil, it is possible that there will not be enough free airflow to allow for effective cooling functioning. A clogged air filter allows debris to accumulate, which might cause the evaporator coils to freeze. The term “frozen” may imply the presence of cool air, however the frozen coils actually obstruct the passage of cool air, resulting in heated air being emitted from the operating motor rather than cool air.
We recommend that you set a monthly reminder to check the status of your air filter at the beginning of each calendar month.
The Solution: If your evaporator coil is frozen, switch off the unit and replace the air filter.
If the coils freeze up again, switch off the unit and call a professional HVAC expert to come out and evaluate the problem right away.

Why Is My Air Conditioner Blowing Hot Air?
In order to keep your house cool and comfortable while facing the North Carolina summer heat, you’ll need a high-quality air conditioner. What happens, though, when your air conditioner quits cooling your home and instead begins to spew hot air into the air instead? Continue reading to find out more about what might cause air conditioners to spew warm air and how you can fix the problem for yourself.
Reasons Your Air Conditioner Is Blowing Warm Air (How to Fix It)
A number of factors might be contributing to the fact that your air conditioner is blowing warm air instead of the chilly air that you’ve been longing for. You may need the aid of a skilled HVAC specialist to resolve some of these difficulties, but you may be able to resolve one or two of them on your own.
Your Thermostat Is Set Incorrectly
We understand that it may seem absurd—but it would be even more absurd to hire an air conditioner repair specialist to travel to your North Carolina home only for the purpose of changing your thermostat settings! The first thing you should look for is a thermostat that is set to “hot,” rather than “cool.” It’s possible that you accidently knocked the switch with your handbag or briefcase, or that one of your children toyed with it, or that any number of unforeseen incidents resulted in this happening to you.
If you want your air conditioner to blow cool air, make sure that your thermostat is set to “cool” setting.
While that may sound like something you’d like to do on a hot day, it’s really the opposite!
If your fan is set to “off,” it will not blow air through your vents whether or not your system is actively cooling your home.
You want to make sure that the fan settings on your thermostat are set to “auto” so that it only blows cool air. It is possible that you are having one of the following problems if your thermostat is already set to “cool” and your fan is set to “auto.”
Your Outdoor Unit Lost Power
While we understand that it may seem absurd, paying an air conditioner repair expert in North Carolina to come into your house only to adjust your thermostat settings would be even more absurd. Make sure your thermostat is not set to “heat” as the first thing you should do. It’s possible that you accidently hit the switch with your pocketbook or briefcase, that one of your children toyed with it, or that any number of unforeseen incidents resulted in this happening. We assure you that it does occur!
Even while it may sound like the kind of thing you want to do on a hot day, it isn’t.
If your fan is set to “off,” it will blow air through your vents whether or not the system is actively cooling your home.
You’re Low on Refrigerant
If your air conditioner is producing warm air, it is possible that the refrigerant levels in your machine are low. In most cases, this implies that you have a refrigerant leak in your system! As a result, your air conditioner will continue to operate and blast warm air, trying to bring the temperature down to the setting you have set on your thermostat. The best course of action will be to call our team at Air Experts, who will come in and find out where the refrigerant leak is in your system so that we can fix it and get your system back up and running.
Your Evaporator Coils Are Dirty
Because your evaporator coils are such a key part of your air conditioner’s operation, keeping them clean is extremely necessary in order for them to continue to perform well and maintain your unit cooling your home efficiently. It’s possible that your evaporator coil is coated with dirt or debris if you failed to arrange a yearly air conditioner tune-up, which will prevent your air conditioner from blowing cold air. All you have to do to remedy this problem is arrange air conditioner maintenance, which will ensure that your system is tuned up, cleaned, and ready to cool down your home.
