Normal Noises
Just like any piece of mechanical equipment, an HVAC will make certain natural noises. Common HVAC noises include humming and the occasional banging sound.
If you notice a drastic change in the noise your unit is making, it’s time to call in the professionals.
Rattling
Rattling is one of the most common noises you might hear from a malfunctioning HVAC unit. Generally, this means something inside the unit has come loose and is waving around unsecured.
If you hear this noise, it’s best to turn the HVAC unit off right away. The unit has likely broken down in some way, and continuing to run it could cause the problem to get worse.
Banging
Banging could mean there’s an issue with the blower. That’s why you may hear banging when this crucial part comes loose from its bearings.
A little banging doesn’t necessarily mean disaster for the HVAC unit. It might just be that something has fallen inside and is causing the sound. If that’s the case, an HVAC professional will get things quickly back on track for you.
Buzzing
Buzzing is one of the most irritating sounds an HVAC unit can make. It also indicates a problem inside the unit that could lead to a breakdown eventually.
This irritating sound could be caused by a loose part vibrating or by something more serious, like a refrigerant leak. It’s best to be on the safe side and shut down the unit before any more damage occurs.
Hissing
A hissing sound coming from an HVAC could mean big trouble. Generally, this HVAC noise means either a leaking air duct or leaking refrigerant.
Both of these problems require urgent attention from a professional technician. Be sure to disconnect the unit while you wait for help.
