Are strange noises coming from your walk in cooler, air conditioner or other parts of your HVAC system? Some noises are completely normal and others can be solved with a quick and easy fix. For the repairs you can’t do on your own, give us a call day or night and we’ll be sure to help. Here’s a quick guide explaining what those weird noises may mean:
Common HVAC Noises and What They Mean
Can’t hear the TV because your vents are so loud?
While some noises are normal, such as a quiet hum or the sounds of air whooshing through the vents, sometimes HVAC systems make strange noises and can become loud, disruptive annoyances in the home. This doesn’t have to be the case.
Check out these common causes of noises in an HVAC system and what you can do about them:
Rattling
Hearing a rattling noise coming from your HVAC system could mean a few things. If it originates from the outdoor unit, chances are you have some kind of debris in the system, such as a twig. (While the grate will protect your system from most large debris, it’s still possible for small things to get through.)
Turn your system off and cut the power to the unit, then remove the debris. If you see visible damage to the condenser coils, compressor, or fan, call your HVAC technician.
If the rattling seems to be internal, from a furnace or other internal component, turn the system off and call your HVAC technician since removing the obstacle isn’t as simple.
Hissing
Hearing a hissing noise most likely means air is escaping from your system. If the noise is coming from the walls, there’s a good chance your ducts are leaking. Not only can this cause noise, it also wastes money because the air that should be circulating throughout your home is leaking into the walls.
Duct repair isn’t really a repair homeowners can do on their own, so if your system is making a loud hissing noise, call a technician. However, if the hissing is light, it could originate from your air vents. Typically when you hear this noise it is because your filter is not “set” right or you have the wrong size filter which is creating the gap in the seal. If this is the case, the air is squeezing past the filter or around it, instead of being pulled through it. This is a simple fix that starts with ensuring the filter is the right size and is placed correctly, leaving no room for gaps.
