Most homeowners in Asheville, NC, install an AC pressure switch to monitor the refrigerant pressure on their air conditioners. This switch prevents your system from running when there’s not enough refrigerant in the line, which can cause significant damage to your compressor and other components. However, the switch can malfunction because of the following reasons.

Blowing Warm Air

Your air conditioning system should blow cold air when functioning correctly. If your system blows warm air, the pressure switch might be faulty. This could cause the compressor to overheat and fail.

Loud Noises

A malfunctioning AC pressure switch can also prevent the fan from running properly, causing loud noises. This indicates your system isn’t getting enough pressure to operate as required. Ensure you call a professional HVAC tech to investigate and repair the issue.

Your AC System Stops Operating

When the pressure switch is in a good state, the system should always run without any issues. However, if your air conditioner stops working, and you can’t identify which component is causing this sudden malfunction, the pressure switch might be at fault. The switch monitors the refrigerant level in your system, so if it gets damaged or broken, this could stop your AC from running altogether.

Intermittent Operation

If your AC system starts and stops intermittently, the pressure switch might be faulty. It could be stuck in the closed or open position, resulting in your air conditioning system not getting enough refrigerant to operate. Always check to ensure the operation of your switch is normal to avoid further damage.

The AC pressure switch can become faulty and prevent your cooling system from operating efficiently.
