Hearing some noise when your HVAC system operates is normal. But certain sounds can be concerning. Keep an ear out for some of these warning sounds that could indicate a problem with the HVAC system in your Longview, Texas, home.

Rattling

Is the rattling noise coming from the outdoor unit? You may have a branch or another piece of yard debris stuck in the motor or fan. Unusual rattling sounds can also indicate that something has come loose in the system, such as the motor bearings or motor mount.

A component within the unit may have also slipped out of place, which could become further damaged if you continue to run it. An HVAC service technician can open the housing to determine what’s causing the sound. You shouldn’t try to do this yourself.

Hissing

If you don’t have a cat, hearing a hissing sound is definitely concerning. This noise indicates that air is escaping the system, which can wreak havoc on its efficiency and lead to issues with indoor comfort and high energy bills. Oftentimes air escapes through a gap or leak in the ducts. You could have a problem elsewhere in the system, though. Therefore, you should get it checked out by a professional right away.

Buzzing

A buzzing sound could happen if the blades of the fan are unbalanced or a coil needs cleaning. It’s dangerous for a homeowner to try to take apart their HVAC system. You should always leave this task to a trained service technician.

Squealing

A squealing sound usually indicates a damaged fan or blower motor. This problem will usually require you to replace the motor. Although in some cases, we may be able to repair the damage. Leaving this issue unchecked can cause more significant damage and impact your system’s efficiency. As a result, you’ll end up paying higher energy and repair costs.
