Reasons Your AC is Blowing Warm Air
Want help troubleshooting your air conditioner problem before contacting us? We’ll describe the most common causes that you may be able to diagnose yourself.
We understand this may sound obvious, but one of the first things you’ll want to check is your thermostat setting. Make sure it’s set to, “auto”. The “on” setting is just a fan and the “heat” setting is for your heater. You’ll also want to make sure that the temperature it’s set to is lower than the temperature in your space so that it “kicks on”.
Your Outside Unit Has No Power
Your air conditioning system is comprised of two main components: the indoor unit (evaporator/blower unit) and the outdoor unit (A/C condenser). Your indoor unit could blow warm air if your outdoor unit has lost power. Check your breaker box or fuse box to see if a breaker has tripped or if there’s a blown fuse.
Your air conditioning units work together to remove heat from your home and exchange it with cool air. If there’s a lot of debris clogging your outdoor unit, your system cannot remove heat efficiently. As a result, you may experience warm air. This is why it’s important to keep the area near your outdoor AC unit clean.
Dirty Air Filter
Another common reason for air conditioning problems is a dirty air filter. A dirty air filter will cut off airflow to the indoor unit and over time the evaporator cooler will freeze. You can identify this by seeing ice or frost on the copper pipes.
Low Refrigerant Levels
Refrigerant is responsible for absorbing warm air. If you have a refrigerant leak, your AC may blow warm air into your home as it struggles to absorb it. You’ll know this is the reason if your indoor and outdoor air conditioning units have ice formations. Only a qualified and licensed HVAC technician should measure your refrigerant levels and add refrigerant when necessary.
The best way to help prevent your air conditioner from blowing warm is to have your system serviced at least twice a year. Regular maintenance will extend the life of your HVAC system and it will address issues before they become costly problems later.
