Why Does My Air Conditioner Make a Loud Noise When It Turns On?

Your heating and air conditioning system should never yell at you! If it is making loud noises, there’s a problem.

Residential Air Conditioner

While it is normal for your heating and air conditioning system to make some noise when it is operating, thanks to a motor and many moving parts, it isn’t so natural if you feel the need take a step back and cover your ears. A loud noise when you turn on your A/C could mean you are in need of some repairs to your system.

If you are experiencing a super noisy A/C, there may be a problem with one of the following three components:

  1. Compressor motor: This is a likely culprit if your air conditioner is only making the loud noise when it turns on. Your compressor motor is one of the most vital parts of your A/C. An additional telltale sign with this possibility is a decrease in your air conditioner’s cooling output.
  2. Fan motor: If your A/C is making a variety of grinding noises, it may mean that the motor needs lubrication or the bearings are bad.
  3. Fan Cage: Your fan blades are behind a cage that functions as a barrier for both the fan and for you to help avoid injury. If the cage is damaged, it can cause grinding against the fan blades, which has the potential to result in major, costly problems.

It helps to be able to identify the problem, but regardless of your suspicions, the very best thing to do is to turn off your air conditioner and call a professional HVAC service like G&M Service to come evaluate your situation right away.
