When your furnace is working properly, it should provide heat without making too much disruption. While it’s normal to notice your furnace making noise as it turns on, other noises are showing your furnace needs immediate professional support.

Here are some of the most common furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Branchville, New Jersey.

1. Furnace Making a Banging Noise

You might 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 can signal there could be several problems. These involve gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s essential to book routine furnace maintenance with Willco Air Conditioning, Refrigeration & Heating Inc.. One of the things our techs perform during this service is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can emit carbon monoxide, which is ordinarily vented outdoors. This hazardous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Willco Air Conditioning, Refrigeration & Heating Inc. advises turning it off and reaching us at 862-345-6896. Excessive natural gas in your furnace or a fractured heat exchanger are serious issues that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide warm air around your home. If the ductwork wasn’t put in properly or is aging, it can be noisy when your furnace is on. This might be the case if your furnace makes a banging noise when it shuts off. Contact Willco Air Conditioning, Refrigeration & Heating Inc. at 862-345-6896 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the right voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or cold air around your rooms, and a capacitor, which starts the motor. If either of these pieces are going out, they will buzz when the furnace starts.

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 critical, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 862-345-6896 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently the result 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 sensing whistling, Willco Air Conditioning, Refrigeration & Heating Inc. can assist you. It’s critical to get loose ductwork fixed quickly, since it can create comfort troubles in your home and drive up your gas costs.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal noise typically means there’s trouble with your furnace’s blower. Shut down your furnace off promptly and contact our professionals at 862-345-6896 for support.
