When your furnace is operating properly, it should provide warm air without generating too much noise. While it’s normal to hear your furnace making noise as it turns on, other sounds are indicating your furnace requires immediate professional help.

Here are some of the most reported furnace noises and what they could mean. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Hasbrouck Heights, New Jersey.

1. Furnace Making a Banging Noise

You might have a critical issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These include gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over the years, so that’s why it’s critical to set yearly furnace maintenance with ACE Solutions. One of the tasks our pros complete during this appointment is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup can break your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can emit carbon monoxide, which is normally emitted outside. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, ACE Solutions advises turning it off and contacting us at 201-426-0650. Too much natural gas in your furnace or a cracked heat exchanger are dangerous troubles that should get immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air throughout your residence. If the ductwork wasn’t installed right or is getting old, it can make a lot of noise when your furnace runs. This could be the case if your furnace makes a banging noise when it shuts off. Get in touch with ACE Solutions at 201-426-0650 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

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

Your furnace relies on an internal transformer to operate 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 distributes hot or cooled air around your rooms, and a capacitor, which starts the motor. If either of these components are failing, 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 related to something little, like an unfastened screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 201-426-0650 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to alert you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again quickly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may also notice whistling while the furnace is on if a floor vent isn’t tight. If you’ve examined your vents but are still noticing whistling, ACE Solutions can assist you. It’s essential to get loose ductwork repaired fast, since it can create comfort problems in your residence and drive up your energy bills.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal racket typically means there’s a problem with your furnace’s blower. Turn off your furnace off immediately and contact our professionals at 201-426-0650 for help.
