5 Possible Reasons Why Your Air Conditioner Is Blowing Warm Air
Clogged Air Filters
Over time, your air conditioner’s air filters will become clogged by dirt, dust, and other debris. Dirty air filters can restrict proper airflow, causing your system to overheat. As a result, your air conditioner may struggle to adequately cool your home or start blowing warm air. If your AC is blowing warm air, check your air filter — if it looks dirty, a simple replacement may resolve the issue.
Low Or Leaky Refrigerant
AC refrigerant is essential to the cooling process, as it’s the substance that absorbs the hot air from inside your home. If your air conditioner’s refrigerant is low or leaking, the system will be unable to cool your home effectively and may even start blowing hot air. Refrigerant issues can be dangerous and should always be handled by one of our licensed HVAC technicians.
Thermostat Issues
If a thermostat is inaccurately sensing the temperature or is set incorrectly, it may not send the correct signals to your air conditioner, ultimately resulting in warmer indoor air. Check your thermostat to ensure it’s set to the desired temperature and replace the batteries if necessary. Faulty thermostat issues, such as a glitchy screen, frequent short cycling, or unresponsive controls, may require repairs or replacement by one of our experienced technicians.
Frozen Or Dirty Evaporator Coils
Sometimes, when proper airflow is restricted by clogged air filters or other system inefficiencies, an air conditioner’s evaporator coils may freeze up or suffer from a buildup of dirt and debris. Frozen or dirty evaporator coils will struggle to cool your home effectively, resulting in a significantly warmer indoor environment. If your evaporator coil appears frozen, turn off the system and allow it to thaw naturally. If it freezes again, contact us to schedule an appointment with one of our experienced HVAC repair technicians.
Outdoor Unit Issues
Most homes have a split HVAC system, which consists of both an indoor and outdoor unit that work together to create a cool and comfortable indoor environment. Your home’s outdoor unit is constantly exposed to the elements, meaning dirt, twigs, and other debris can interfere with its cooling process by damaging the fans or restricting airflow. Routinely cleaning around the outdoor unit is an effective way to prevent obstructions and ensure optimal efficiency.
What To Do If Your AC Is Blowing Hot Air
If your air conditioner is blowing hot air, there are several steps you can take to troubleshoot the issue before calling for service. The following are a few things to check if your air conditioner is blowing hot air.
- Check the air filter and replace it if it’s dirty.
- Double-check your thermostat’s settings and batteries.
- Make sure the outdoor unit isn’t obstructed.
- Check your breaker box for tripped breakers related to your AC.
