When your furnace is working like it should, it should provide warm air without making too much disruption. While it’s normal to notice your furnace making noise as it starts up, other disruptions are signaling your furnace needs immediate professional support.

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

1. Furnace Making a Banging Noise

You could have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be several problems. These include gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over the years, so that’s why it’s important to schedule seasonal furnace maintenance with Fal-Ken Heating & Cooling Corporation. One of the things our professionals perform during this appointment is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise if ignition is delayed. The resulting gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can emit carbon monoxide, which is normally emitted outdoors. This dangerous gas can be fatal 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 reaching us at 631-460-5159. Excessive natural gas in your furnace or a broken heat exchanger are serious issues that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide heated air around your residence. If the ductwork wasn’t designed properly or is getting old, it can be loud when your furnace is on. This might be the problem 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 figure out the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cooled air throughout your residence, and a capacitor, which turns on the motor. If either of these components are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be related to something small, like a loose screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and calling our heating specialists 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 needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing could need to be lubricated. 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 hearing your furnace making a whistling noise, it’s frequently 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 tight. If you’ve examined your vents but are still sensing sound, Fal-Ken Heating & Cooling Corporation can help. It’s essential to get loose ductwork taken care of quickly, because it can make comfort troubles in your house and drive up your utility expenses.

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 typically means there’s trouble with your furnace’s blower. Shut down your furnace off right away and contact our pros at 631-460-5159 for support.
