When your furnace is running like it should, it should provide warm air without generating too much sound. While it’s common to hear your furnace making noise as it starts up, other noises are showing your furnace should get immediate professional help.

Here are some of the most common furnace noises and what they could be signaling. If your furnace is making an atypical 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 could have a serious issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be several problems. These range from gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over time, so that’s why it’s essential to book seasonal furnace maintenance with Fal-Ken Heating & Cooling Corporation. One of the tasks our professionals perform during this service is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can discharge carbon monoxide, which is regularly vented outside. This toxic gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Fal-Ken Heating & Cooling Corporation urges you to turn it off and contacting us at 631-460-5159. Excessive natural gas in your furnace or a ruptured heat exchanger are critical troubles that require prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air throughout your house. If the ductwork wasn’t put in right or is getting dated, it can be noisy when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Contact Fal-Ken Heating & Cooling Corporation at 631-460-5159 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically indicates an electrical situation, 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 is loose, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or chilly air across your house, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be related to something minor, like an unfastened screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 631-460-5159 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubed. We realize that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again fast.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still noticing sound, Fal-Ken Heating & Cooling Corporation can provide support. It’s critical to get loose ductwork fixed quickly, since it can result in comfort problems in your home and inflate your heating bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you notice 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 now and call our pros at 631-460-5159 for support.
