With summer in full swing, your air conditioner is working hard to keep your home cool. While it’s normal to hear noises coming from your unit, homeowners should be able to tell which sounds are a sign of an underlying issue. The certified heating and air conditioning technicians at Mill Creek Heating in Turner, OR, are here to share various types of AC noises and their meanings.

3 Types of AC Sounds

1. Banging

If you hear banging coming from your air conditioner, this is a sign that there may be a loose component rolling around in the unit. Depending on the part, the entire compressor may need to be replaced. Call a heating and air conditioning contractor and keep your AC unit turned off until they arrive to inspect it and make the necessary repairs.

2. Clicking

Clicking at the start-up and shut-down is normal for an AC unit. If you hear it as the system is running, however, this is a red flag. It may be a sign of a failing thermostat or a larger electrical problem. Call in a contractor for an inspection, as they may have to replace the thermostat or perform another repair.

3. Buzzing

Buzzing noises can be a sign of minor damage like clogged debris, or in more serious cases, an electrical problem. There could also be a component within the system that is coming loose. First, clean out the debris from the filters in the system. If you still hear noises, call in a technician, as they may have to replace the faulty component or repair a damaged seal.
