Common AC Noises and what They Mean: Identifying Possible Issues Early

Summer is here, and it’s time to crank up the air conditioning. However, nothing ruins a relaxing day indoors like strange noises coming from your AC unit. Don’t let these noises go unnoticed because they can be a sign of potential serious problems that could lead to costly repairs or even a complete system breakdown. In this article, we’ll cover the most common AC noises and what they mean. We’ll also provide tips on how to fix these issues to keep your home cool and comfortable.

Common AC Noises and what They Mean: Identifying Possible Issues Early

Banging or Clanking Noises

If you hear a loud banging or clanking noise coming from your AC unit, it’s likely due to a loose or broken part. This could be a piston pin, connecting rod, or crankshaft, and if left untreated, it could cause serious damage to your unit. Contact a professional HVAC technician immediately to diagnose and fix the issue.

Squealing or Screeching Noises

A high-pitched squealing or screeching noise coming from your AC unit is often due to a problem with the belt or motor bearing. This issue can cause excessive wear and tear on your unit, leading to a complete system breakdown. Schedule a service call with a licensed HVAC technician to have the problem fixed.

Clicking Noises

Clicking noises are a common sound when your AC unit turns on or off. However, if you hear clicking noises coming from your unit constantly, it could be a sign of an electrical issue. This could be due to a faulty thermostat or wiring problem. Call a professional HVAC technician to troubleshoot and fix the problem.

Hissing or Whistling Noises

If you hear a hissing or whistling noise coming from your AC unit, it could be due to a refrigerant leak. This issue can lead to reduced cooling power, increased energy bills, and potential health risks from inhaling the refrigerant fumes. Contact an HVAC technician to repair the leak and recharge your unit with the proper amount of refrigerant.

Customer Testimonials

“Manny came to repair my air conditioner. It took several procedures and he finally replaced my new motor. It seems to be doing the trick. He also put in a new thermostat . Mine was 21 years old so it was time. He was pleasant and easy to work with; answered all my questions, and there were a lot, until I understood. I would recommend this company and this tech unconditionally!!!” - Midge Abel
“Jason was pleasant, professional, and helpful. He clearly talked about my options and answered all my questions. I’d gladly do business with him again.” - Katrine Cady
“Our upstairs AC stopped working yesterday and I chose this business because of their 5 star reviews. They did not disappoint. Rachel was amazing. She is not only friendly but she is very professional. She was ready to send someone out within an hour! John came out and was very knowledgeable, professional and above all, honest. You don’t see that very often anymore. I will definitely come to them for my future AC/Heater needs.” - Heidi Hedina
