When your furnace is running properly, it should deliver warm air without creating too much sound. While it’s normal to notice your furnace making noise as it turns on, other sounds are indicating your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Holbrook, New York.

1. Furnace Makes a Banging Sound

You might have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a few problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over time, so that’s why it’s important to book routine furnace maintenance with Fal-Ken Heating & Cooling Corporation. One of the tasks our technicians perform during this work is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The following gas buildup can crack your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can leak carbon monoxide, which is regularly emitted outside. This toxic 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. Significant natural gas in your furnace or a fractured heat exchanger are serious troubles that should get fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide warm air throughout your house. If the ductwork wasn’t designed correctly or is getting old, it can be noisy when your furnace is heating. This could 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 pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically 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 is loose, you might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or chilly air throughout your space, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be the result of something little, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with 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 running, it’s making an effort to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing could need to be greased. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You might also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still sensing noise, Fal-Ken Heating & Cooling Corporation can assist you. It’s critical to get loose ductwork taken care of quickly, since it can make comfort problems in your home and increase your utility expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s an issue with your furnace’s blower. Switch off your furnace off right away and reach our pros at 631-460-5159 for support.
