Causes of 3 Common AC Noises in Mansfield, TX

Normally, an air conditioner should operate with minimal noise, producing little more than a gentle hum. Loud, unusual noises from the AC system in your Mansfield, TX, home almost always indicate an underlying problem. Let’s review some common AC noises and what’s likely to cause them.

Screeching Noises

These sounds are usually signs of a failing motor within your AC system, the most common explanation for which is a malfunctioning fan blower. Fan motors tend to squeal when they’re on the verge of breaking down. This noise may come from either the indoor or the outdoor portion of your AC system, depending on precisely which motor or motors are faulty.

Hissing Noises

If refrigerant should ever leak out of your air conditioner, it’ll typically do so while in a gaseous state and will probably flow out through a tiny hole in the AC system’s refrigerant lines. That being the case, the flowing gas will create a hissing sound.

Refrigerant is extremely toxic and can seriously damage your health if you inhale enough of it. If you hear this noise, we strongly recommend that you leave your home as quickly as possible and request AC repair services. An HVAC service technician will locate the source of the leak, repair it and refill your air conditioner with refrigerant.

Banging AC Noises

A banging sound usually indicates that a component of your AC system has either come loose or has completely broken. This part may be anywhere, but you should cast suspicion upon your system’s compressor first and foremost. Different components within the compressor may wear out and begin rattling around after the system reaches a certain age.

Upon hearing any unusual noises from your AC system, you should turn to the professionals right away. Call Performance Heat and Air for quality maintenance and replacement services in Mansfield, TX.
