3 HVAC Sounds You Should Never Ignore

HVAC Sounds You Shouldn't Ignore
Posted on in Blog

The HVAC system that keeps your home in North Chesterfield, Virginia, comfortable will make noises as it powers on and off. It'll also make sounds as the air flows through the ductwork. The critical thing to realize is that there are many noises your HVAC system may make that aren't typical. While some of these noises can be due to the age of the system, there are some HVAC sounds that you shouldn't ignore.

Grinding

When grinding or high-pitched squeaking occurs, it means that one of the moving parts in your HVAC system isn't working properly. This can be a serious problem that needs to be addressed to preserve your system.

First, check your filter and turn your system off and on. If the noise continues or begins again later, shut the system down and contact an HVAC service technician. It could be something as simple as a worn or blown belt. But it could be something more severe like a pump or motor failure.

Rattling

Rattling noises in an HVAC system often signal problems with the fan. While this repair may be simple, failure to address it immediately can result in more damage to other parts, causing more expensive repairs or even completely damaging your system.

If you have a problem with your fan system, continuing to run it will make it worse. So if you hear rattling noises, shut your system down until you can get an HVAC service technician to look at it.

Hissing

If you hear hissing noises coming from inside your home or around your outdoor unit, you'll need to call an HVAC service technician. This noise is often associated with coolant leaks or ductwork that's cracked and leaking. Leaky ductwork can decrease efficiency and cause your unit to work harder.

While some HVAC sounds are normal, you should treat most as warning signs. If you notice any of these sounds coming from your HVAC system, contact Air Excellence, Inc. at 804-885-3888 today to determine the cause and get your HVAC back up and running.
