Why Is My Air Conditioner So Loud? | Lawes Heating and Air Conditioning Company in Shrewsbury

Is your air conditioning unit roaring rather than purring? All air conditioning units make noise when running; after all, they are large machines with quite a few moving parts that work hard to keep you cool and comfortable. Older units tend to be louder than newer units which now have improved designs to help reduce noise. Thankfully, regular maintenance inspections by Lawes Heating and Air Conditioning Company in Shrewsbury will help keep minor noise issues in check, such as those caused by dirty fan blades or parts requiring lubrication. But some sounds can be more concerning than others.

Why Is My Air Conditioner So Loud?

Different noises may be used to diagnose the nature of a HVAC problem. Ignoring it could result in a bigger problem than just annoying sounds. Put in the ear plugs instead of calling the experts and you could end up with a unit that cannot be fixed, or where fixing it will be quite expensive.

4 Common Air Conditioning Noises

1. Rattling

Rattling noises are usually not very serious. The most common cause of this frustrating noise is that something is loose. It could be from a loose panel or AC duct in need of tightening. If you hear a thumping, clacking or banging and you could be looking at a problem with the blower assembly or motor. The motor assembly should be inspected by a qualified technician.

2. Squeaking or squealing

Mild squeaking is likely not serious. It could just be a pesky bearing in need of lubricant, dirty fan blades out of balance or a bad belt that needs replacing.

3. Grinding

Grinding noises are more much more serious. It could be that a bearing is going to fail, and if it’s not replaced soon, it could damage other parts of your HVAC unit. If you hear a grinding sound, call Lawes Heating and Air Conditioning Company in Shrewsbury asap.

4. Hissing

Hear hissing? It could just be from loose ductwork (not so serious) or leaking Freon (much more serious). If it is coming from your air conditioning unit, the most likely cause could be from leaking Freon. To read more on this subject, click here. When in doubt, give us a call.
