5 Sounds That Spell Trouble for Your AC

Without regular maintenance or repairs, even a brand-new air conditioning unit can develop problems. Fortunately, most central AC units can let their owners know that something is wrong with the sounds they produce. Below are just five different noises that might spell trouble for your AC in Puyallup.

1. Rattling or Banging

You might hear a loud rattling noise that comes from inside the AC unit, in which case there is likely a loose component. For example, there may be loose wiring or a loose motor. Out-of-balance parts will make more of a type of clanking noise. Another possible cause of rattling is the presence of debris in the air ducts. The rattling may change to a banging if the loose part is not repaired. A failing motor bearing might also explain any banging noises.

2. Grinding

If the blower fan belt breaks, it can produce a grinding sound. The pistons in your AC’s compressor may also grind against each other. AC compressor replacements are expensive and may necessitate that you get a new AC. At Puyallup Heating & Air Conditioning, we can install new systems anywhere in Puyallup. We’re a Carrier Authorized Dealer.

3. Hissing

Prolonged hissing or screaming may be the result of a refrigerant leak, a serious issue that could harm your health and the environment.

4. Squealing

This noise could signify any number of things. For example, the blower motor unit may need to be lubricated, or the motor bearings and blower motor belts may be getting worn.

A bad outdoor or indoor fan motor can create a continual squealing sound. This should be differentiated from the squealing sound that you might hear when the AC system starts up, which is perfectly normal.

5. Clicking

Likewise, clicking heard when the AC turns on and off is normal. Constant clicking, though, may be because of a defective relay or control.
