How to Fix a Noisy Air Conditioner

Nobody wants to live without air conditioning in Dallas, but nobody wants to deal with a noisy AC system. Is there anything you can do? The answer is yes!

While all air conditioners will make some sound, they shouldn’t be loud. In this article, we’ll explore some common reasons your AC is noisy, how to resolve the issue, and when to call a pro for help.

Common Causes of a Noisy Air Conditioner

A lot of problems can lead to a noisy air conditioning system. Some of the most common issues include:

  • Loose connections: Electrical connections, nuts, and bolts can all rattle around while an AC unit runs.
  • Damaged blower motors: Air conditioner blower motors can struggle to spin correctly after years of wear and tear.
  • Dirty condenser coils: When your condenser is dirty, it can struggle to operate efficiently and cause noise.
  • Air filter issues: If your air filters are too dirty or are installed incorrectly, they can make noise.

These are just a few issues that often cause air conditioners to be noisy. Depending on the exact problem with the system, a quick fix could resolve the issue, or you may need the help of a pro.

When DIY Is Worth a Try

Sometimes your air conditioner can have smaller issues. Not every problem needs to be fixed by a professional. If you think you can do it yourself, consider these tips:

Replace Your Air Filters

When your air filters become too dirty, they can cause your AC system to struggle. Consider removing your old air filters and installing new ones to see if that alleviates the noise issues.

Clean Your Coils

Air conditioners work harder when the outdoor unit is dirty with leaves and other debris. You can clear the area around your external unit and remove any caked-on debris to see if that resolves the problem.

Check for Loose Parts

Every air conditioner features a wide array of parts and connectors. When some of them come loose, they can cause a rattling sound. Make sure everything is tightly screwed in on your internal and external AC units.

Check for Refrigerant Leaks

Low refrigerant levels can cause your AC system to work overtime to keep your home cool. Call an AC repair technician for a refill if you’re low on coolant.

These are some ways you could resolve the noise issues. If these tips don’t work, it may be time to call a pro.
