Strange Noises and Air Conditioning Repair

What’s that bump in the night? If it’s been a hot summer day and you’ve been running your air conditioner full-time, it may be something in your air conditioning system. Strange noises in your air conditioner usually indicate a problem, even if your air conditioning system is still running normally. At Your Service Plumbing, Heating & Air technicians have seen many times how ignoring certain sounds can lead to bigger problems. Think your air conditioner may be making a strange or odd sound? It may be time to call an expert.

What’s That Noise?

The best way to truly know what is wrong with your air conditioner is to have it inspected by a trained technician, but there are some common sounds that can indicate problems in specific parts of your system:

Hissing

The most common problems associated with hissing noises are refrigerant leaks or compressor issues. Refrigerant leaks hiss because the chemical itself is pressurized, particularly after it leaves the compressor. Refrigerant leaks can also be accompanied by bubbling noises as the refrigerant bubbles out of the system.

Hissing from a compressor can indicate that the pressure in within the compressor has gotten too high – a potentially dangerous situation. If you suspect that the hissing sound you hear is coming from the compressor, turn your system off immediately and call for a technician.

Banging/Bumping/Clunking

Are you hearing something bang or bump around your air conditioning system when it starts to cycle? During normal use, screws, small components, mountings and fan blades can become loose, causing banging/bumping/clunking noises in your system as they move around or hit other parts of your air conditioner. While the initial problem may not be serious, allowing a loose component to stay loose and/or continue to make contact with other parts of your air conditioner can become a serious problem.

Snapping/Popping

Snapping or popping sounds coming from your air conditioner can often indicate an electrical issue. There are many wires working within your system, and with normal use, these wires can become frayed, corroded or disconnected. Because the electricity in your air conditioner is powered by your property’s electricity, it is always better to have a trained professional work on any electrical issues that may be happening with your air conditioning system.

Don’t Ignore Strange Noises

Just as sneezing can be an indication of a possible cold, strange noises coming from your air conditioner can indicate developing problems. Most problems do not go away on their own; in fact, they tend to get worse as time goes on. If you have heard something in your air conditioning that sounds off, call At Your Service Plumbing, Heating & Air today and schedule air conditioning service in Salt Lake City with one of our technicians.
