Odd Sounds That Your AC System Might Make

Published by Derek Cormier

Summers in Florida can be brutal. The last thing you want is for your air conditioner to stop working in the middle of a heatwave. However, we all are familiar with the tell-tale signs that our AC system is on its last legs.

AC units will often make strange noises before they completely break down. We have all heard strange noises emanating from our AC systems at one point or another. Some of these sounds may be completely normal while others may be indicative of a serious problem.

We’ll help you figure out which noises notify you to call AC repair in Palm Bay, FL immediately.

Loud Banging Noises

Banging noise is usually caused by debris or dirt getting caught in the fan blades. The best way to fix this problem is to turn off the AC unit and clean out the fan blades with a brush or a vacuum cleaner attachment. If the noise persists, it could be indicative of a more serious problem such as a broken fan blade. In this case, you will need to call for repairs right away.

Hissing or Sizzling Noises

A hissing or sizzling noise is usually caused by leaks in the refrigerant line. These leaks can be dangerous as they can cause the AC unit to malfunction and can also lead to health problems if inhaled. If you hear this noise, it is best to turn off the AC unit and call for professional help immediately.

Clanking Noises

If you hear clanking noises coming from your AC unit, it is most likely due to loose parts. Over time, screws, bolts, and other fasteners can loosen and cause the metal components of your AC system to bang against each other. In most cases, this problem can be easily fixed by tightening the loose fasteners. However, if the clanking noise is accompanied by a burning smell, it could be indicative of an electrical problem.

Grinding Noises

Grinding noises are usually caused by a failing compressor or motors. The motors in AC units are responsible for powering the fans. When they fail, they will make a loud grinding noise. The compressor is also one of the most important parts of your AC system and it is responsible for circulating the refrigerant. If the compressor fails, it will need to be replaced.

High-Pitched Squealing Noises

A high-pitched squealing noise is usually due to a loose belt. The belts in your AC unit help to keep the various parts moving smoothly. When a belt becomes loose, it can cause a lot of friction and noise. In most cases, this problem can be easily fixed by tightening or replacing the affected belt.

Who To Call?

If you hear any strange noises coming from your AC unit, it is best to contact a professional for help. The sooner you can identify the problem, the easier and cheaper it will be to fix it.
