Phoenix summers are known for their extreme heat, with temperatures regularly reaching well above 100°F. Its desert-like climate with low annual rainfall brings intense conditions to residents, making a reliable and efficient air conditioner necessary for comfort and safety.
A well-working AC is essential for maintaining home comfort, so if your system starts blowing warm air, it can quickly create an unbearable environment. Understanding the possible causes of this issue can help you address the problem before the heat becomes overwhelming.
In this guide, we’ll discuss troubleshooting your AC and common reasons your air conditioner may be blowing warm air.
How To Troubleshoot Your AC
If your AC is unexplainably blowing warm air, you can conduct troubleshooting to find the root cause of the problem before calling a professional. Here are some reasons your AC may be blowing warm and what to do about it:
Dirty Air Filters
Dirty, clogged air filters will restrict your HVAC system’s airflow, limiting cool air distribution around your home. You should regularly check your air filters and clean or replace them as necessary, preferably every month.
Dirty Evaporator Coils
To function efficiently, an AC blows warm air over evaporator coils to cool it before distributing it throughout your home. This process will be hindered if your air conditioner’s evaporator coils are dirty. Cleaning off your evaporator coils is an important step in routine air conditioning maintenance.
Miscalibrated Thermostat
Your thermostat is in charge of maintaining your HVAC’s temperature production. If the system is on the fritz, your AC may not pick up the correct signal, leading to warm airflow. Inspect your thermostat to ensure it’s reading the correct temperature, and replace the batteries or recalibrate the settings if it’s not.
Leaking Refrigerant
Refrigerant is a key component in efficiently cooling the warm air that blows over the evaporator coils. If your system’s refrigerant has leaked and levels are low, your unit can’t adequately cool the warm air. This issue requires professional attention for safety.
Tripped Circuit Breaker
If your circuit breaker trips, it can disrupt the power to your outdoor condenser, preventing it from properly completing the cooling process. Check your circuit breaker to see if this is the case, and reset it as needed.
Compressor Failure
Once air is cooled over the evaporator coils, it’s converted to a low-pressure gas that’s then compressed before being pushed through your home’s ductwork. If the compressor fails, this process will also fail. Diminished airflow, loud screeching noises, and a slow AC startup are common signs of this issue.
