3 HVAC Noises You Should Get Checked

We want to take good care of our equipment at home but how do we know when something’s wrong? For your Heating, Ventilation, and Air Conditioning (HVAC) system know that it will give you indications to you when it needs fixing or to be checked. One way it does this is by talking to you, not thru words but by noises.

Make sure to be keen and don’t immediately dismiss sounds you hear from your HVAC to be nothing. You may investigate a bit more but avoid opening anything or doing complex repairs with your system unless you are trained in this matter.

Screeching, Grinding, Or Squealing

If this is coming from your HVAC it could mean important components that have come off or have become slightly unfastened so it comes into contact with other parts of your system. You may wait for a while if and observe if this continues. If it does then have a professional visit as soon as possible.

It’s important that someone certified to do so, comes over to check on it because if left ignored this could mean wear and tear on your parts and this may cause damage. This will eventually cost you more money compared to what you are spend when have this addressed right away.


If you don’t own a pet snake, or any animal that’s expected then don’t panic as this could just be air finding its way outside of your system through a narrow gap. If you find it easy to ignore this and not let it annoy you, that doesn’t mean you should disregard this situation. Air escaping through a hole that shouldn’t be there in the first place means a waste of electricity as it was supposed to contribute to meeting required temperatures in areas where it was actually intended to go to.

It would be great if you find this opening yourself so that it can be instantly be patched up by the professionals as soon as they arrive, however if you are unable to locate it there is nothing to worry about a these people are trained to determine where this is situated.


If rattling noises are heard then this may mean your vents are improperly sized and might actually be too small. When your equipment is too powerful, the extreme pressure caused by it could cause your ductwork to move causing the sound.

Although be on a look out for certain foul smells or animal noises that may come from your ducts as it might also possibly be an infestation. Critters may find this ideal in comparison to the current state of the outside environment, especially since you are able to customize the air to desirable temperatures.

A well-experienced HVAC company will know what to whether it’s the former or latter so there isn’t much to be concerned about.
