Why Your AC System in Palo Cedro, CA, Makes So Much Noise

When everything is in working order, the air conditioner in your Palo Cedro, CA, home should emit nothing more than a quiet hum. Too much noise can indicate a problem with your air conditioning system. Keep reading to find out why you might be hearing certain AC noises.

Squeaking

A squeaking noise suggests that your AC system’s internal components need attention. For example, motor bearings might need lubrication to ensure that everything moves smoothly. Misaligned belts might cause a high-pitched sound.

Hissing

In almost every case, hissing coming from your AC system means you have a refrigerant leak. Refrigerant, under pressure, hisses as it escapes through small cracks or holes. Refrigerant is the liquid that makes it possible for your AC system to remove heat from your home, so you’ll want to address any leaks as quickly as possible.

You’ll need a professional service technician to handle the refrigerant leak because it can pose a safety risk. Also, it’s illegal for untrained, unlicensed individuals to work with refrigerant.

Banging

The compressor plays a vital role in pressurizing refrigerant, allowing it to transfer heat away from your home. If you hear a banging noise, your compressor may have loose parts rattling around inside of it. The compressor is a complex part, and disassembling it isn’t easy, so you’ll likely require assistance from a skilled HVAC service technician.

Humming

Well-functioning air conditioners often make quiet humming noises when they operate, but loud humming could point to loose parts inside your system. Alternatively, you may have to address an overloaded circuit breaker, a broken fan motor or a malfunctioning contact relay switch. A service technician can check everything, figure out how best to resolve the problem and eliminate the loud humming.
