Three Common HVAC Noises and What They Mean

December 26, 2017

Has your HVAC unit in your Fayetteville, NC home been making odd noises? Investigating the root cause of these sounds will help you determine if the unit needs to be fixed or replaced. For example, a soft humming noise is not only normal but usually indicates that everything is working properly.

On the other hand, you might have gotten used to some other sounds that are actually a bad sign. Avoid losing heat on a cold winter night in the Raleigh and Fayetteville areas by learning when to contact a professional technician about your HVAC noises.

Hissing Sounds Accompany a Larger Heating Bill

Do you hear a hissing noise when your heater is running? If it’s minor, you can probably fix the problem yourself by checking your filter. Do you have the right filter size and does it fit properly? Making these quick adjustments often stops minor hissing.

However, loud hissing is typically a bigger issue that will require duct repairs. Failure to do so will increase your heating costs and cause your family to live with unpleasant sounds.

Check Out Rattling Immediately

Rattling can accompany something as simple as a small piece of debris lodged in the outdoor unit. In that instance, a visual inspection should help you find and remove the problem, but make sure you turn your heater off first. If the rattling is coming from an internal component, power the unit down and contact a technician for assistance.

Clanking Is Bad News

Clanking happens when parts become loose inside the unit. Therefore, this sound needs to be taken very seriously because it can lead to an expensive repair. Taking steps to get the problem fixed quickly will usually reduce the damage.
