Why Is My Air Conditioner Making Noises?


post img

Your air conditioner is vital for keeping your home cool. So, when it starts making strange noises, you’ll want an AC technician to diagnose and solve the problem quickly. After confirming the noise is coming from your AC, the next step is to determine what kind of noise it is.

Keep reading to learn the common sounds of AC trouble and how to fix it!

Is your AC making a strange noise, and you think it might need to be repaired? Contact us to schedule an appointment.

What Type of Noise Is It?

Different AC sounds can indicate different problems. In addition to identifying the specific sound, it’s important to note when the sound is being made. Is your air conditioner making strange noises when it first turns on or the entire time it’s running?

This information is crucial to fixing the issue. Contact us today if you notice strange AC noises, including: 

  • Banging or clanking: If you hear a banging noise, it’s likely due to a loose part in the compressor.
  • Clicking: A clicking noise while your unit is running likely indicates your AC has an electrical problem. 
  • Buzzing: The most common culprit of buzzing sounds is a refrigerant leak or dirty air filter.
  • Squealing: When your AC fan needs repair, it will often release a squealing sound.
  • Chattering or screaming: These sounds are startling and for good reason. If you hear these noises, call an HVAC tech immediately. Your HVAC needs to be inspected and repaired right away.

Troubleshooting Your Air Conditioner

While it may be tempting to try to repair your AC yourself, it isn’t recommended. Without the proper knowledge and skills, you can ultimately spend more money and time than it would take a professional to repair your system.

However, there are some simple things you can do to help prevent AC problems, such as:

  • Keep the area around your AC clear of debris
  • Schedule preventative AC maintenance at the start of spring each year
  • Change your air filters every 60 to 90 days
  • Listen for any unusual noises and, if you hear any, don’t wait to call a professional
