4 Signs You Have a Faulty AC Pressure Switch in Redlands, CA

Fixing AC System

A pressure switch is an important component of any air conditioner in Redlands, CA. It helps to regulate the pressure in the air conditioner and maintain safe, efficient operation. Unfortunately, AC pressure switches can become faulty over time due to wear and tear or other issues. Here are four signs that you may have a faulty AC pressure switch:

Inconsistent Air Conditioning

Air conditioning should always provide a consistent level of cooling. If your system is starting and stopping, cycling off and on more frequently than usual or not providing the same level of cooling that it used to, you may have a faulty AC pressure switch.

Erratic Fans

The fans in an air conditioner should run at a consistent speed when the cooling system is in use. The AC pressure switch helps to regulate the speed of the fan. If faulty, the fan may start and stop erratically or run at an inconsistent speed.

Faulty fans can cause your air conditioner to work harder than it should, leading to higher energy bills and possible damage to other components. Schedule regular maintenance on your AC system to help prevent this.

Strange Noises

A faulty pressure switch can cause your air conditioner to emit strange noises when operating. This could include loud buzzing, clicking or humming sounds from the compressor unit. If you hear any of these noises during operation, have a professional inspect your AC pressure switch.

Warm Air Blowing

When an air conditioner runs, it should blow cool air. If your air conditioner blows warm air, the problem could be a faulty pressure switch. A malfunctioning AC pressure switch can cause the system to overheat and blow warmer-than-usual air.

A properly functioning AC pressure switch is essential for the safe and efficient operation of a cooling system. Contact Hush Air Heating & Air Conditioning if you notice any signs of trouble from your air conditioner. We can inspect and repair the pressure switch to restore your AC system’s performance.
