HVAC Noises and What They Mean

Blog Image

Your home’s HVAC unit provides indoor comfort all year round, and when it does its job well, you don’t even notice it. HVAC systems typically emit a humming sound during normal operation, but if you start hearing unnatural noises coming out of it, that’s a sign that something might be wrong.

Ainsworth and Co. Air Conditioning – Heating, your local HVAC repair company, discusses some of the notable HVAC noises, the meaning of each and what you should do once you hear them.

Clanking Sounds

The sound of clanking indicates a serious problem and must be addressed as soon as possible. It may be brought about by loose blades, the blower motor fan, or pipes rubbing against each other. Any of these could damage the interior components of the unit if not fixed right away. If you start hearing this noise, it would be best to turn off your HVAC unit and call a NATE-certified technician.

Hissing Sounds

Hissing noises are brought about by leaks in the ductwork. A light hiss either means the filter wasn’t set right or you got the wrong filter size, and as a result air is escaping through the gap. You can fix this problem on your own by making sure that your filter is the right size and has been installed correctly. Loud hissing, on the other had, indicates the need for professional help. Our air conditioning replacement and repair pros can work on your HVAC unit, repairing any problems and ensuring that it performs efficiently.

Rattling Sounds

Rattling sounds in your HVAC system may be eminate from either the outdoor or indoor unit. When the noise comes from the outdoor unit, it’s possible that there’s a twig or some other debris stuck in there. Be sure to turn the system off before removing them, and call our repair pros if you notice obvious damage to the heating and cooling system components. Do the same if you hear rattling sounds coming from within the indoor unit.
