What To Do If Your Air Conditioner Blows Out Warm Air

When the summer heat is at its peak, there’s nothing more frustrating than having your air conditioner blow out warm air instead of providing the cool relief you need. Several factors can contribute to this issue, ranging from simple fixes to more complex problems. In this article, we will discuss what to do if your air conditioner is blowing out warm air and provide guidance on resolving the issue.

 1. Examine the thermostat.

Check your thermostat even if you believe it is set appropriately, especially if you share a house with someone who could have “adjusted” it. It’s likely that the warm air in your home is only being circulated by the fan on your air conditioner.

When your thermostat displays “on,” the fan for the system is running. This means that even when the interior unit isn’t cooling it, the fan will continue to blow air through the ducts and out of the vents. For your air conditioner to chill and dehumidify your interior air as the fan circulates it, your thermostat must be set to “cool” or “auto”.

2. Verify that the external appliance is powered.

Your air conditioner uses a lot of power to run because it is a high-powered equipment. If there is a brief power surge, your outside unit’s circuit breaker can trip. Check your circuit breaker panel for a tripped switch if your air conditioner is spewing heated air.

Additionally, if your air conditioner has recently undergone maintenance, the exterior unit was probably switched off at some time while the repair was being done. Check the box on the wall outside next to your unit to make sure the equipment is receiving power. It’s possible that the technician neglected to switch the outside unit back on.

3. Examine the exterior unit to see whether it’s crowded.

The condenser, which is the exterior unit of your air conditioner, radiates heat. As a result, it requires space for ventilation on its top and sides. (This is one of the causes for our disgust whenever we notice a unit put beneath a deck or crawlspace.) Make sure there is at least 1 foot of clearance all around the condenser as well as a minimum of 5 feet of vertical clearance. Remove any weeds, and cut back any bushes or hedging that are encroaching on the machinery.

4.  Verify the air filter.

Most manufacturers state that disposable air filters last for up to 90 days; the operative word here is “up to.” That filter will become dirty far sooner than the 90-day period if you use your air conditioner continuously for weeks on end. The filter will get filthy even more quickly if you have pets.

So how can a filthy air filter result in an air conditioner blowing heated air? Your air conditioning system cannot circulate air when an air filter is covered with dust. This causes the following issues:

To produce chilly air, the air conditioner must work harder than usual.

The interior coil, also known as the evaporator coil, contains refrigerant, but not enough hot air is blown over it.

As a consequence, your AC may experience overheating in certain areas while experiencing freezing condensation on the evaporator coil. The coil cannot properly chill your interior air after it has frosted over. A frozen evaporator coil also increases the risk of the system’s compressor overheating and failing.

You need to install a new filter and wait for the ice to melt if it has created a coating on your evaporator coil. To hasten the thawing process, let the fan on your AC system run, but make sure the “cool” setting is not engaged. Once the ice has melted, you may start using your air conditioner again, but you might want to have a professional check the system for any issues. Shut off your AC system and call a professional to check for a potential refrigerant problem if you start using it again and the ice appears.


You will want the assistance of an AC SKY  expert if the aforementioned troubleshooting techniques fail to resolve your air conditioning issue. At this stage, one of these three issues will probably be the cause of the cooling issue:

  • There is a leak of refrigerant.
  • The condenser’s fan is broken.
  • New compressor is required for the system.


When your air conditioner blows out warm air instead of cool, it’s important to take immediate action to address the issue. Check thermostat settings, inspect air filters, clear obstructions around the outdoor unit, and examine the condenser unit for proper functioning.
