Why Is My Air Conditioner Blowing Hot Air

Your air conditioner is working hard to keep your home cool during this heat wave.

But instead of breathing chilled relief, you’re breathing hot air from your vents. Your air conditioner’s blowing hot air.

Why is my air conditioner blowing hot air? There could be a variety of reasons for this. Let’s take a look at some of the most common reasons for this AC issue and how to fix it.

Your Thermostat Is Set Incorrectly

When your AC is blowing hot air, it could be caused by your thermostat being set too low. If you’re not familiar with how your thermostat works or how to set it correctly, it is important to read the user manual to understand the settings and how your AC should be set.

It is important to note the difference between the temperatures you desire to set your thermostat to and how hot the air on the incoming AC is running. If the thermostat is set to lower than the incoming AC, then the air conditioning will be blowing hot air instead of the desired cold air. 

Your Outdoor Unit Lost Power

When your outdoor unit loses power, this can mean that your air conditioner is not properly home cooling your home. Without the power running through the outdoor unit, your air conditioning system will not be able to process the air and cool it down to your desired temperature.

This can put a strain on your compressor, which is located in the outdoor unit, and cause it to overheat, which is why your air conditioner blows hot air. Ensuring that your outdoor unit has an adequate power supply is essential for your air conditioning system to work properly.

You’re Low on Refrigerant

When your air conditioner is blowing hot air, it is likely that the system is low on refrigerant. This is because the refrigerant is responsible for absorbing heat from the air in the home so that it can be cooled and distributed throughout the space.

If the refrigerant is low, then the air cannot be cooled as efficiently, leading it to feel like warm or hot air. To fix this problem, consider hiring a HVAC repair company to test, fill, and fix any air conditioning issues with the system, such as leaks or blockages. 

Your Evaporator Coils Are Dirty

The evaporator coils of your air conditioner are responsible for chilling the air blowing from the unit. However, if the evaporator coils become too dirty, they are unable to absorb heat which will result in hot air being blown out.

This is the most common cause of air conditioners blowing hot air. To fix this issue, the evaporator coils will need to be cleaned. This requires the air conditioner to be shut off and disassembled so that the coils can be thoroughly cleaned.
