Air Conditioning Issues & Troubleshooting Tips From John Nugent & Sons

Air Conditioner Won’t Turn On
First, you should check your thermostat batteries and replace them if they’re dead. If your batteries are fine, or have been replaced, ensure that your thermostat is set to cooling mode. If the thermostat is on, in cooling mode, and set properly and the AC unit still isn’t turning on, check your circuit breaker. If you have a tripped breaker, reset it by flipping it off and then back on. If your AC still won’t turn on, you should call a professional.
AC Isn’t Producing Cold Air
Check your air filter. If it is dirty, it might be restricting airflow and can cause your condenser to freeze up. Change your filter monthly to prevent these issues.
Air Conditioner Is Making Strange Sounds

There is a variety of sounds that your air conditioner might make that indicate different issues:

Hissing – This is usually caused by a refrigerant leak.
Clicking when AC is turned on/off – It could be a relay problem.
Thumping, rattling, or banging – Usually indicates an issue with the blower or motor.
Screeching – Is typically caused by the compressor or fan motor.
Buzzing – Produced by faulty electrical components.

Outside AC Unit Is Leaking Water

If your AC is leaking some water on a hot or humid day while the unit is running, it’s nothing to be concerned about. When the outside temperature is 60 degrees or lower and the AC is running, the unit might freeze up a little and leak water when it melts; this is also normal. There are, however, other reasons your outside unit might leak water that indicate a problem:

Air filter needs to be replaced
Faulty installation
Clogged drainpipe
Low coolant
Cracked condensate pan

Evaporator Coil Is Frozen

Your air conditioner’s evaporator coil can freeze if the unit doesn’t receive enough airflow to operate properly. Obstructed vents or ducts, a dirty air filter, or a fan malfunction are possible causes of the insufficient airflow within the system.
