Central air units are designed to keep you cool in the summer, but you don’t want them to continuously run. Units that won’t shut off can increase your energy bills. Here are some common reasons why your central air may keep running and when to call residential AC repair in Madison, AL.
Dirty or Frozen Condenser Coils
Condenser coils(coils on the outside unit)often get blocked by dirt, especially when you haven’t serviced the unit in a long time, which prevents them from cooling the air properly. Turn the unit off, then use a coil cleaner to remove dirt. Sometimes constant running and warm air causes frozen coils that usually indicate a coolant leak. In this case, you’ll need to get it checked by an HVAC service.
Blocked Air Filters
A unit that continuously runs could be caused by dirty air filters. If filters get clogged or dirty, the unit has to run more to cool the air. Remove filters and clean them according to instructions for your model or replace disposable filters that are too dirty or moldy.
Thermostat Problems
Thermostats should shut off the compressor when the room reaches the preset temperature so ensure it is not set too low and set on “auto”. A temperature set too low may cause the unit to work harder to cool the room so test the thermostat by raising the room temperature. If the unit continues to run after reaching the temperature, get it professionally checked.
