Common AC Noise Causes That Should Concern You

When you’re at your property checking things over, you may hear strange noises coming from the air conditioner. Some noises won’t mean much, but others could require a repair. Not only do those sounds distract and annoy clients and tenants, the unit could stop working, creating discomfort. The following are some common concerning noises and what they mean.

Buzzing

Most unusual buzzing noises indicate an issue with the electrical work of the unit. This can become a dangerous issue if not handled right away. Some buzzing sounds could also point to motor and compressor problems, though they might just require a little maintenance.

Whistling

When you hear your AC whistling, it typically points to problems with the ductwork. If your system is fairly new, it may not be compatible with your old ductwork, requiring installation of new ducts. Whistling could also mean your ducts have become clogged in some way, so the air is trying to squeeze its way through somewhere else. Cracks, breaks, and other duct damage will also make a whistling noise and need to be repaired.

Rattling

You may have already guessed a rattling sound means something is loose. Most motors have many working parts, as well as hardware to hold it all together. If any of those components become loose, you could hear a rattling sound. It’s important you contact the professionals to tighten everything back up and put things together correctly so the AC will continue working properly all season.

Humming

Your AC unit probably hums all the time, but if it begins to get extremely loud, that’s when it becomes a problem. Filters collect pollen, dust and dirt, but when they become too full, it clogs the system and it has to work extra hard to produce cool air. One quick fix you might try is changing out the filter.
