3 Symptoms of a Bad AC Pressure Switch

If your air conditioner’s pressure switch is bad, it can cause all sorts of problems with your system. Here are some common symptoms of a bad AC pressure switch in your Augusta, GA, home:

Air Conditioner Blows Warm Air

The AC pressure switch is responsible for turning the system on and off in response to changes in pressure. If the switch is malfunctioning, it can cause the system to stay on when it should be off or vice versa. This can lead to a buildup of heat inside the unit, which will eventually blow into the room as warm air.

If you notice that your air conditioner is blowing warm air, have a certified AC repair service technician inspect it as soon as possible. They’ll diagnose the problem and make any necessary air conditioning repairs.

Strange Noises

When the AC pressure switch malfunctions, it can cause the compressor to run continuously. This can lead to a buildup of pressure in the system, which can cause strange noises.

In some cases, the compressor may emit a loud humming noise. In other cases, it may make a clicking sound. No matter what, it’s important to have service technicians diagnose and repair the issue to avoid further damage to the air conditioner.

AC System Turns Off Unexpectedly

If your AC unit turns off unexpectedly — even if it’s working fine one minute and then suddenly shuts down the next — it could be because of a problem with the pressure switch. When the pressure in the unit gets too high, it’ll trip the switch and cause the unit to turn off until the pressure drops to a safe level again.
