When your furnace is working correctly, it should deliver heat without generating too much disruption. While it’s expected to hear your furnace making noise as it starts up, other sounds are showing your furnace needs immediate professional assistance.

Here are some of the most reported furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in Holbrook, New York.

1. Furnace Makes a Banging Sound

You might have a critical situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These involve gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over the years, so that’s why it’s essential to schedule annual furnace maintenance with Fal-Ken Heating & Cooling Corporation. One of the tasks our techs perform 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 can crack your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can discharge carbon monoxide, which is regularly vented away from your home. This hazardous gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Fal-Ken Heating & Cooling Corporation recommends turning it off and calling us at 631-460-5159. Too much natural gas in your furnace or a broken heat exchanger are dangerous issues that should get immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air across your residence. If the ductwork wasn’t designed correctly or is aging, it can be noisy when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Get in touch with Fal-Ken Heating & Cooling Corporation at 631-460-5159 and we’ll pinpoint the problem.

2. Furnace Makes a Buzzing Sound

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or chilly air throughout 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 Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be the result of something minor, like a loose screw, or something major, like a broken part. In either case, we advise shutting your furnace off and contacting our heating professionals at 631-460-5159 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubed. We are aware that maintenance often slips your mind, but our professionals can get your furnace heating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s likely due to 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 sensing noise, Fal-Ken Heating & Cooling Corporation can provide support. It’s critical to get loose ductwork fixed quickly, since it can create comfort issues in your home and drive up your heating bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket frequently means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and contact our professionals at 631-460-5159 for help.
