1. Furnace Making a Banging Noise
You could have a critical issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a couple of problems. These range from gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy over the years, so that’s why it’s important to book annual furnace maintenance with Faust Air Conditioning and Heating. One of the tasks our technicians complete during this appointment is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can emit carbon monoxide, which is ordinarily emitted away from your home. This dangerous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Faust Air Conditioning and Heating advises turning it off and contacting us at 979-323-6130. Too much natural gas in your furnace or a cracked heat exchanger are serious problems that necessitate immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move warm air around your house. If the ductwork wasn’t installed right or is getting dated, it can be loud when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Faust Air Conditioning and Heating at 979-323-6130 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes warm or cooled air across your house, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it might be due to something small, like an unsecure screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 979-323-6130 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to get your attention it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubricated. We realize that maintenance often slips your mind, but our pros can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You might also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still hearing whistling, Faust Air Conditioning and Heating can assist you. It’s important to get loose ductwork fixed quickly, as it can result in comfort issues in your residence and inflate your gas expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s an issue with your furnace’s blower. Turn off your furnace off immediately and contact our professionals at 979-323-6130 for help.
