When your furnace is operating like it should, it should give warm air without generating too much sound. While it’s expected to hear your furnace making noise as it starts up, other sounds are showing your furnace requires immediate professional support.
Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making an atypical noise, our friendly heating professionals are here to help with the best furnace repair in Hasbrouck Heights, New Jersey.
1. Furnace Makes Banging or Knocking Sounds
You might have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a few problems. These include gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over time, so that’s why it’s important to book routine furnace maintenance with ACE Solutions. One of the tasks our techs perform during this service is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes more time. The following gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can leak carbon monoxide, which is normally vented away from your home. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, ACE Solutions advises turning it off and calling us at 201-582-2806. Excessive natural gas in your furnace or a fractured heat exchanger are hazardous troubles that necessitate prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver hot air around your residence. If the ductwork wasn’t designed right or is getting old, it can be noisy when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Call ACE Solutions at 201-582-2806 and we’ll determine the problem.
2. Furnace Buzzes Constantly
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually means there’s 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 needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or cooled air around your residence, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace turns on.
3. Furnace Rattles
If your furnace is making a rattling noise, it may be the result of something little, like a loose screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 201-582-2806 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to tell you it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubricated. We know that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also be aware of whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still noticing whistling, ACE Solutions can provide support. It’s important to get loose ductwork repaired fast, since it can make comfort troubles in your house and inflate your gas expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise frequently means there’s a problem with your furnace’s blower. Shut down your furnace off instantly and reach us at 201-582-2806 for support.
