When your furnace is operating like it should, it should deliver warm air without making too much noise. While it’s normal to notice your furnace making noise as it starts up, other noises are signaling your furnace requires immediate professional support.
Here are some of the most common furnace noises and what they could be indicating. If your furnace is making an atypical noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Neptune City, New Jersey.
1. Furnace Making a Banging Noise
You may have a serious issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a few problems. These range from gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy as time passes, so that’s why it’s important to set yearly furnace maintenance with Aggressive Mechanical. One of the things our professionals complete during this appointment is clean your furnace’s burners. When this piece gets grimy, you may hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can leak carbon monoxide, which is normally vented outside. This toxic gas can be fatal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Aggressive Mechanical recommends turning it off and reaching us at 732-806-5536. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous troubles that necessitate prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air throughout your residence. If the ductwork wasn’t designed right or is aging, it can be noisy when your furnace runs. This can be the issue if your furnace makes a banging noise when it shuts off. Call Aggressive Mechanical at 732-806-5536 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cold air around your residence, and a capacitor, which turns on the motor. If either of these parts are going out, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be the result of something minor, like a loose screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 732-806-5536 for help.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to get your attention it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing might need to be greased. We are aware that maintenance often slips your mind, but our techs can get your furnace running quietly again quickly.
5. Furnace Whistles
When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also hear whistling while the furnace is operating if a floor vent is loose. If you’ve checked your vents but are still sensing whistling, Aggressive Mechanical can provide support. It’s critical to get loose ductwork fixed quickly, since it can create comfort issues in your house and drive up your energy bills.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Switch off your furnace off immediately and contact us at 732-806-5536 for support.
