Top 3 Causes of a Noisy Air Conditioner

AC UnitStephen from Afterglow here,

Last weekend, I was outside washing the car and I could hear my neighbour’s noisy air conditioner from three houses over. Yikes! Not only is a noisy air conditioner annoying to your neighbours, it’s almost ALWAYS a sign that something has gone wrong with your unit, so it’s important not to ignore it.

There are few possible causes for a loud air conditioner:

  • Fan issue: Fans can be noisy if they are loose, or if there is an obstruction in the way, for example, a screw or a bolt. For a fan to work properly, it needs to be kept clean and properly maintained.
  • Motor problem: A motor that’s in need of lubrication can cause a humming noise. You can prevent this by oiling the air conditioner motor at the beginning of each summer. Yes, it’s that simple!
  • Dirty Coil Fins: One of the main issues that outdoor coil fins run into is dirt. When coil fins become overly dirty, it can impair the proper functioning of an air conditioning unit.

In some cases, an air conditioning unit is beyond repair by the time it starts being noisy; however, much of the time the unit will only need minor work done in order to start functioning quietly again.

To track down the cause, and to keep your air conditioner working well and operating efficiently, it’s important to have it inspected by a qualified technician!
