Reasons Why Your AC Unit Is Blowing Hot Air

June 20, 2022 7:19 pm Published by Leave your thoughts

Summer is almost here, and the weather is getting warmer. This means that you already need some cooling in your home. However, you might not be getting the cooling you need because your air conditioning is blowing hot air. You are likely wondering – why is my air conditioner blowing hot air? There is probably a problem with your air conditioning system. Here are the common causes of air conditioning blowing hot air and how to fix it.

1. Clogged Air Filters

The air filters in your AC unit are responsible for catching all the pathogens and dust particles in your home’s air. Once the air filters become clogged with dust particles and dust, they prevent the proper circulation of cool air in your home. This means that your AC will be blowing hot air in your home.

The solution: To solve this problem, you need to replace the air filters in your AC unit. We recommend replacing the air filters every 90 days to keep your AC working in optimal condition and prevent extensive damage to the unit due to system overwork.

2. Dirty Evaporator Coils

The evaporator coils play a critical role in how the AC unit cools your home’s air. When the evaporator coils become dirty, their performance reduces, which means they won’t be able to cool the air in your home correctly. As a result, your AC will blow hot air.

The solution: Switch off the AC system completely from the circuit breaker. Spray a mixture of warm water and household cleaning detergent on the evaporator coils and let it soak for about 10 minutes. Use a soft cloth to gently wipe the evaporator coils clean, removing the accumulated dirt and debris.

3. Refrigerant Leak

The refrigerant is critical for your AC unit to cool the air in your home properly. If there is a refrigerant leak within your AC unit, it won’t be able to effectively cool the air in your home. Thus, the AC unit will be dispersing hot air in your home. You can spot the refrigerant leak by looking for signs of frosting on the evaporator coils.

The solution: Call an HVAC technician to repair the source of the leakage and refill the refrigerant.

3. Malfunctioning Compressor

The compressor is the component responsible for cycling the refrigerant from gas to liquid through your AC unit to cool the passing hot air. If the compressor is malfunctioning, it means that the refrigerant isn’t cycling from gas to liquid through the unit, and the hot air isn’t being cooled. If the air filters and evaporator coils are clean and there aren’t any signs of a refrigerant leak but the unit still blows hot air, this indicates the compressor may be malfunctioning.

The solution: Call an HVAC technician to come to check your AC unit.
