Because all models of furnaces have sounds or noises, it can be tough to identify the contrast between your system’s regular, faint humming sound and a peculiar sound that indicates a problem.
Because of this, a lot of homeowners find it challenging to differentiate an insignificant sound from one that requires a prompt and serious repair.
When you start to notice abnormal noises originating from your home’s furnace, whether we go over it in this article or not, we at Delaware Heating & Air strongly suggest you give us a call promptly for an expert examination. Trivial problems can progress into more significant issues if disregarded.
When You Hear A Banging Noise
Often, banging or popping noises indicate the interior of your furnace has gotten dirty. This dirtiness can affect the combustion of the gases inside, which triggers a variety of reasons for concern, the worst of which would be the fracturing of your heat exchanger. The best way to prevent this from happening is proper annual maintenance, which keeps everything clean inside, among other things.
Your ductwork could be an alternate reason for this noise if it is swelling and contracting in the cold weather. Sheet metal contracts when it’s exceptionally cold, but then it suddenly expands when your furnace cycles on again, bringing back the heat. This expanding and contracting causes stress in the area close to the seams of the ducts. When this happens, the sheet metal buckles out, generating the banging racket you are noticing.
Scraping Sounds Originating From Your Furnace
Scraping sounds emitting out of your heating system could indicate your furnace has developed serious issues with its blower wheel. If you discover this noise, we advise you to turn off your furnace quickly and give us a call.
Two potential things that could produce this sound include:
- The blower wheel on your unit is not functioning, and a professional should replace it.
- The blower might have become loosened, and it might be tapping the casing.
Rattling Sounds Originating From Your Furnace
Rattling noises starting from your heating system is not usually a reason for great concern. The bulk of these problems can be fixed quickly.
If you hear them, we advise you to:
- Tape down some duct tape to the loose ducts or screw in some more screws on them.
- Slide a rubber or cork pad under your furnace.
Squealing Sounds Arising From Your System
Squealing sounds often mean your motor needs to be serviced, or your blower belt is due for replacement. If it’s your motor, it usually means parts of it require lubricating, which might not be as pressing as these other dilemmas, but still, we advise you get it serviced by a professional.
Whistling Sounds Originating From Your Unit
Situations that might be the reason for a whistling noise include:
- The gaps in your ducts are too little. When this is causing the sound, you’ll discover it is arising from a small hole around the place where the duct and your furnace meet.
- If your air filter is plugged up, the fan will suck air from anywhere it is able. The best way to determine if this is the cause is to take out the filter and see if it stops.
- Your air filter is so filthy and coated with dirt and particles that they’re stopping the flow of air. In this position, you need to remove the filter and replace it with a new filter.
