Why Is My Air Conditioner So Loud?

Posted on June 24th, 2020 by Devine Bros

Those with window or wall units might be used to their systems making noise throughout the day, but central air is usually supposed to have a more quiet presence, only letting out a simple hum. But there is a major difference between the system’s usual hum and a more roaring blare. There are a few reasons for this issue, and you don’t want to ignore these sounds. Here’s what to consider when it comes to a noisy A/C: 

Sounds You May Be Hearing:

  • Rattling: if you hear a rattling noise coming from your HVAC system, it most likely means some kind of debris has found its way into the compressor fan. This could be because of sticks and leaves, or it could mean a loose nail or bolt fell out and into the fan. 
  • Scraping: for older units, the lubrication surrounding certain parts may have gone dry over time. This leads the scraping and grinding sound you may hear, a direct result of certain parts of your unit dragging against each other. 
  • Hissing: the hissing sound coming from your AC unit could be a direct result of a leaky refrigerant, which should be fixed immediately. This could be dangerous for your family and for the unit and should be looked at and fixed, ASAP.

How To Fix The Issue

While you can consider changing your filtration system so that no excess debris enters your unit, you should really consider a total upgrade. An HVAC professional will ensure that all issues are taken care of and will fix any broken parts or leaky refrigerants. Regular air conditioner maintenance will help guarantee that these problems don’t come up again and allow your system to remain at a gentle hum throughout the summer!
