Faulty AC Pressure Switch in Finksburg, MD

AC Problems? You May Have a Faulty Pressure Switch in Finksburg, MD

September 3, 2022

A faulty pressure switch can cause all sorts of issues, from reduced cooling power to complete system failure. Read on to learn about some possible signs of a faulty AC pressure switch in your Finksburg, MD, home.

Strange Sounds Coming from Your AC

The pressure switch helps to regulate the flow of refrigerant. If the pressure switch isn’t working properly, it can cause a variety of problems, including strange noises.

These sounds can range from a gentle hissing to a loud banging, and they’re usually caused by an imbalance in the refrigerant levels. If you notice any strange sounds coming from your AC unit, be sure to contact a qualified AC repair person for further diagnosis and repairs.

The AC Isn’t Turning On

If you have attempted to turn on your AC unit but it won’t power on, this could be a sign that the pressure switch is faulty. Check to see if the switch is on. If it is, then the problem may lie with the pressure switch.

The AC Keeps Shutting Off

A properly functioning pressure switch will turn off the unit when there isn’t enough refrigerant flowing through it. However, if the switch isn’t working properly, it may keep turning off even when there’s no need to do so.

The House Isn’t Cooling Down Properly

If your home isn’t cooling down as well as it should be — even when you have the AC set at a lower temperature — this could also be a sign that you have a faulty pressure switch. A malfunctioning pressure switch can prevent your AC unit from providing adequate cooling power, resulting in a warmer than desired house temperature.
