A malfunctioning air conditioner can be anything from a nuisance to a crisis. Here are some of the most common A/C problems and what you can do to resolve them.
The Unit or Condenser Isn’t Running
- Check the A/C to make sure it’s plugged in and receiving electricity from a suitable power source.
- If the system is properly connected to a power source, check the circuit breaker to see if the breaker has been tripped. If you have a fuse box, check it to see if the fuse has been blown. Reset the breaker or replace the fuse and start the A/C again.
- Make sure the thermostat is set to an appropriate temperature. Lower the thermostat by five degrees or so to see if that makes the air conditioner kick on.
Air Conditioner Produces Inadequate Cooling
- Lower the temperature settings at the thermostat a few degrees to see if that makes up for the reduced cooling.
- Check the evaporator to see if it’s dirty. Clean it if possible, then turn the A/C back on for a few hours to see if cooling has improved.
- Make sure your indoor environment isn’t receiving excessive heat gain from sunshine coming through windows, use of heat-generating appliances, or overheated attics causing downstairs temperatures to increase.
Unit Produces No Cool Air
- Make sure the condenser in the outdoor unit is clean and not blocked by weeds, grass, trees or other vegetation. Trim and remove vegetation and make sure any vents near the condenser are free of blockages.
Unit Cycles Improperly
- If the A/C is switching off and on incorrectly, make sure the condenser and evaporator are both clean and free of obstructions.
- Make sure the air filter is clean and that there’s nothing blocking airflow to and from the unit.
