Air Conditioner Repair FAQ’s

How often to service my air conditioner?

You should ideally service your air conditioner once a year during the spring before the hot weather kicks in. This will prevent costly and inconvenient breakdowns in the middle of the summer and ensure your comfort.

Why is my air conditioner not cooling?
If your air conditioner is not cooling it may be for the following reasons: your air filter is dirty and has not been changed, the outdoor unit is covered in debris (leaves, grass, etc.), or your thermostat is set to ON instead of AUTO. If the problem involves broken parts or refrigerant leaks you should contact a technician to help.

Why is the air conditioner fan not working?
If your air conditioner fan is not working it could be as simple as a clogged air filter or a breaker or switch set to off. If the problem, however, is more mechanical like faulty wiring, motors, thermostat, or a frozen coil you may need the help of a technician.
Why do air conditioners freeze up?
Air conditioners freeze up for a variety of reasons. The most common ones include mechanical failures with lines or blower fans, insufficient airflow across the evaporator coil, low levels of refrigerant, and low refrigerant pressure due to low outdoor temperatures.

Why won’t my air conditioner turn on?
If your air conditioner won’t turn on the most common causes are: a tripped breaker or a blown fuse, dirty air filters or evaporator coils, a refrigerant leak, a mechanical problem (such as with the motor or wiring), your thermostat needs to be replaced, or your unit is turned off. If you cannot solve the problem yourself contact a technician.
