What’s That Sound? 4 AC Noises and What They Mean

If you’re hearing strange noises coming from your air conditioner, you may be alarmed. And for good reason! Unusual sounds coming from your air conditioner are never a good sign. In fact, you need to schedule AC repair in Plano, TX, right away anytime your air conditioner begins to make unusual noises.

You can keep reading to learn more about four common air conditioner sounds that signal trouble. Then give our team a call to schedule your tune-up or repair appointment to get your air conditioner back working at its best and prevent any unexpected breakdowns.

Clicking

On one hand, clicking can be a completely normal sound to hear coming from your air conditioner. In fact, your air conditioner clicks a few times at the beginning and end of each cooling cycle as it turns on and off. 

But if clicking is persistent, it indicates that something is preventing your air conditioner from starting easily. Sometimes there are problems with the starter or the motor that need to be addressed. Anytime your air conditioner clicks persistently, you need to call and schedule service.

Banging

Banging is a very loud and obvious noise, unlike clicking. If your air conditioner is clicking, it may be easy to ignore or even miss completely because it is such a quiet sound. But banging is easier to identify and equally as serious. 

If something is banging, it usually means that a large part inside of your unit is loose or broken off completely and knocking against something else. If left to continue on, banging could do a lot of damage to your air conditioner. It’s a good idea to turn the unit off completely to prevent additional problems until our team can take a look at it. 

Rattling

Rattling is similar to banging in that it’s possible small components are loose and moving around. An example might be a small bolt or screw. Alternately, two pieces may be loosening up and tapping together gently, resulting in a rattling sound.

It’s also possible that rattling is a problem with your ductwork and not your actual air conditioner itself. When ductwork comes loose, it often rattles as airflow moves through and the pieces move together. Rattling is especially concerning if it is persistent and never seems to stop during operation.

Humming 

If it sounds like your air conditioner is humming, this can be an early red flag that the capacitor on the outdoor unit is going bad. The capacitor is a fairly small component and it is very easy to fix if something has gone wrong. But without a working capacitor, your air conditioner won’t turn on at all. This part is responsible for giving an extra power boost when the unit first turns on for a cooling cycle.

For any noises from your air conditioner that are out of the ordinary, don’t delay. You don’t want the problem to become worse.
