Air conditioning is a must-have to keep your home or office comfortable during the hot summer. However, there are times when an AC unit may blow warm air instead of cool, which can be frustrating and uncomfortable. We understand the importance of a properly functioning AC unit during the summer months at AVS Heating and Air Conditioning. That’s why we specialize in air conditioning installation, repair, and maintenance services in Fairfax, VA, and surrounding areas.

In this blog post, we will discuss 9 possible reasons why your AC is blowing warm air and what steps you can take to fix the issue.

1. Thermostat Problems: The thermostat controls the temperature of the AC unit, so if it’s not working correctly, the AC may blow warm air. Check the thermostat settings and batteries to ensure they are correctly configured and functioning.

2. Dirty Air Filters: Air filters become clogged with dirt and debris over time, which can restrict air flow and cause the AC to blow warm air. Change the air filters regularly to maintain optimal performance.

3. Refrigerant Leaks: If the AC unit leaks refrigerant, it can’t cool the air properly. Our professional technician will need to repair or recharge the refrigerant system.

4. Frozen Evaporator Coils: The evaporator coils are responsible for absorbing heat from the air, and if they become frozen, they can’t perform their function correctly. Make sure the unit is not blocked by debris, and check that the airflow is not restricted.

5. Faulty Compressor: The compressor is responsible for pressurizing the refrigerant, and if it’s not working correctly, the AC won’t be able to cool the air. This is a job for our AC professional.

6. Damaged or Broken Fan: A damaged or broken fan can impede airflow, causing warm air to blow from the AC unit. This will also require a technician to fix it.

7. Incorrectly Sized Unit: If the AC unit is not sized correctly for the space it’s cooling, it may need help keeping up and blowing warm air.

8. Electrical Issues: A problem with the electrical system of the AC unit, such as a blown fuse or tripped circuit breaker, can prevent it from working correctly.

9. Clogged Condensate Drain: The condensate drain carries away any moisture the unit collects. If it becomes clogged, it can cause the unit to freeze up and blow warm air.
