Symptoms of a Bad AC Pressure Switch in Sunrise, FL

It’s springtime in Sunrise, FL, and many homeowners dread the thought of an air conditioning system breakdown. Unfortunately, when you least expect it, your AC may malfunction and display signs that something is wrong with the pressure switch. Below are some symptoms of a bad AC pressure switch that you should know.

Humming Noises

Humming noises from your outdoor unit is one possible indication that something is wrong with your pressure switch. If you hear loud humming or buzzing noises from your unit, the contact points inside the switch may have become corroded or blocked and need to be replaced. It’s important to troubleshoot the source of this noise and take care of it quickly before it leads to further damage.

Longer Cycles

If your air conditioner’s cooling cycle runs longer than usual, this could indicate a problem with the switch itself. This issue could be caused by debris blocking the flow of refrigerant, which can lead to electrical overload within the unit. If left unchecked, this can cause more serious problems, such as circuit failure or complete shutdown of your air conditioning system.

Tripped Circuit Breaker

When you have multiple appliances hooked up to home power circuits, and one shuts off unexpectedly due to a faulty switch, then it might trip an additional circuit breaker. It’s important to check if any other appliances in the house are affected by this issue and ensure they’re operating correctly before calling in professional help.

Reduced Cooling Power

If you notice that there seems to be less cold air coming out now compared to when your system is working properly, then there could be something wrong with either the compressor or its associated parts, such as contact points inside the pressure switch itself. In such cases, calling in an HVAC technician is necessary so they can diagnose what’s causing reduced cooling power and replace any faulty components accordingly.
