Noises from the outside unit of your air conditioner can be irritating and even disturbing, especially when you’re trying to sleep. Although these kinds of noises are common in Palm Bay, FL, homes during the summer months, there are several different causes. Here are some of the most common AC noises and ways to remedy them.

1. Loud Rattle

A loud rattle often occurs when there’s a vibration from loose parts resulting in metal banging against each other. The best way to fix this problem is to change those parts or tighten any loose screws that may be causing it. Contact a professional for this problem to avoid further damage to your air conditioner.

2. Squealing Noise

A squealing noise may come from a blower or compressor motor wearing out, and that needs replacement. This problem can occur when you have an older unit, so you should check with a professional about the best course of action. You may also hear a squealing noise if your AC doesn’t get regular maintenance.

3. Humming Noise

A humming noise emanating from your AC could be from a dirty fan, which need cleaning or replacement. Checking and cleaning the filter regularly also helps remove dust or dirt that could be causing this problem. If left unchecked, it could lead to more repair issues or interruption of comfort when you need it most.

4. Thumping Noise

A thumping noise usually indicates an issue with the compressor or a loose part in the outdoor unit. The problem could also be due to something hitting the outdoor unit, like a falling branch or debris. It can become more of a problem when the outdoor unit is under pressure to keep your home cool on extra hot days.

5. Whistling Noise

A whistling sound from the air conditioner may come from the accumulation of debris, like a build-up of dust or lint inside the air ducts. If you hear it when the unit’s running, the airflow is likely restricted. If you notice it when your AC unit is off, it could be due to an obstruction or damage to your home’s walls and ductwork.

Your central air conditioner needs regular servicing. Routine maintenance helps increase the lifespan and efficiency of your equipment along with providing you with safe, cool air. For information about AC repairs, contact Extreme Air & Electric, Inc.
