Why is My Air Conditioner So Loud?

Stephen Jabro

Living in the Missouri summers means running the air conditioning to stay safe and comfortable at home. When you turn it on, your AC system should make a low-volume humming noise. However, if you hear noises from your AC system, you likely have other issues involved.

Here are some tips to learn about the types of noises coming from your air conditioner and how to fix them.

Reasons for a Loud AC

If your air conditioner makes rattling noises, buzzing noises, or high-pitched whistling noises, there’s something wrong with it. Some of the common issues with noisy air conditioners, including

  • Broken or loose parts
  • Displaced blower fan blades
  • Clogged air filters and duct systems
  • Loose wiring and electrical issues
  • Wear and tear
  • Refrigerant leaks
  • Failing thermostat

Anytime you wonder, “Why is my AC so loud,” it’s likely due to any of these issues. Fortunately, you can inspect these issues yourself or hire a professional HVAC technician.

How to Fix Loud Air Conditioners

Be cautious if you decide to repair the air conditioner yourself. Once you hear loud noises from your cooling system, turn off the air conditioner. Then, remove the top with a screwdriver. With a flashlight, look at the inside of your AC unit for any breaks in the blower motor.

Another option is to change the air filter, vacuum the air ducts, and remove any obstacles near the units. For instance, outdoor air conditioning units should sit near the house, approximately two to three feet off the ground. If weeds or other obstructions are nearby, the outdoor unit can malfunction. Therefore, keep this area clear to avoid costly repairs.
