When your furnace is running properly, it should provide warmth without generating too much noise. While it’s expected to hear your furnace making noise as it starts up, other noises are showing your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating professionals are here to assist with the best furnace repair in Norton, Virginia.

1. Furnace Makes a Banging Sound

You could have a serious issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be several problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty as time passes, so that’s why it’s critical to book yearly furnace maintenance with HCE Systems. One of the things our technicians perform during this appointment is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup may break your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can leak carbon monoxide, which is ordinarily emitted outdoors. This toxic gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, HCE Systems recommends turning it off and contacting us at 276-302-0076. Too much natural gas in your furnace or a broken heat exchanger are hazardous issues that require prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver warm air around your house. If the ductwork wasn’t put in right or is getting old, it can make a lot of noise when your furnace runs. This can be the issue if your furnace makes a banging noise when it shuts off. Call HCE Systems at 276-302-0076 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you notice 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 work on the correct voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air throughout your space, and a capacitor, which triggers the motor. If either of these components are going out, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be related to something minor, like an unsecure screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 276-302-0076 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to alert you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubed. We know that maintenance sometimes slips your mind, but our professionals can get your furnace operating quietly again rapidly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also hear whistling while the furnace is operating if a floor vent is loose. If you’ve examined your vents but are still hearing whistling, HCE Systems can provide support. It’s important to get loose ductwork taken care of quickly, since it can create comfort troubles in your residence and inflate your energy bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise typically means there’s a problem with your furnace’s blower. Switch off your furnace off now and call our pros at 276-302-0076 for support.
