HVAC Noises

The Meanings of HVAC Noises

July 25, 2019

With most HVAC systems, you’ll occasionally hear the sound of air moving through your ductwork. You might also hear a click when your system turns on or off. Other sounds from the air conditioner in your Mt. Pleasant, South Carolina, home could make living a quiet life or getting good night’s sleep difficult. To make your home more comfortable and avoid a breakdown, listen for these HVAC noises that indicate a problem:

Banging

You might hear banging or popping sounds when your ductwork changes temperature. This annoying noise might also come from a malfunctioning part or component. Have a professional inspect your HVAC system to find and fix the source of the sounds before the problem becomes severe and costly. Having your ducts cleaned or replacing the parts of your ductwork that are loudest can help, as well.

Rattling

Rattling noises usually come from loose components such as screws. They generally don’t lead to severe issues. But they can waste energy and force your HVAC system to work harder. As a result, they can shorten its life and make additional repairs necessary.

You should also pay attention to rattling from your air conditioner’s outdoor unit. It could be a sign of a failing motor, especially if it’s loud.

Grinding or Squealing

A grinding noise could mean your HVAC system needs more oil or another lubricant, while squealing is often a sign of a malfunctioning or damaged belt or motor. Having a belt replaced or getting a professional to add more oil is a quick and inexpensive way to get rid of these bothersome noises. As a result, you’ll also prevent costly breakdowns.
