Although modern air conditioners are designed to run quietly, it’s common to hear some noise while they’re in use. However, if your unit begins making loud, obnoxious sounds, it could indicate a problem with your cooling system. Failing to take action could lead to more extensive and expensive AC repairs. Here are a few noises your unit could make and what they might signify.

How to Identify Strange Sounds Coming From Your AC

1. Buzzing

A distinct buzzing noise typically implies an electrical issue. This means you could have a faulty fan motor, circuit breaker, or relay switch, which could pose a fire hazard. It may also be something simpler, such as loose parts, debris in the unit, a fan blade out of balance, a dirty condenser coil, or a clogged air filter. Turn off the unit in case it is electrical and call an AC repair expert.

2. Clanking

If your AC is clanking, it’s generally another sign of loose parts. This sound often appears when the compressor has come loose, which would likely need a replacement. It could also mean the fan blades have gone off balance and they’re hitting other parts while in motion. In either scenario, these problems will worsen if overlooked.

3. Squealing

One noise that can be particularly alarming is squealing, as it’s similar to a high-pitched scream. This is usually associated with a worn or misaligned fan belt. The sound can be intermittent as the belt expands and contracts according to the temperature and humidity levels. Eventually, the belt will break, so you want to schedule AC repair before you’re left without cool air.

4. Banging

Consistent banging is a telltale sign your AC needs professional attention. In most cases, it’s evidence of a loose or damaged part inside the compressor. Often, a new compressor is necessary. It could also be indicative of an unbalanced blower. The only way to properly fix the problem is to have a technician check it out.
