When your furnace is working properly, it should deliver warmth without generating too much noise. While it’s normal to catch your furnace making noise as it starts up, other sounds are showing your furnace needs immediate professional assistance.

Here are some of the most frequent furnace noises and what they might mean. If your furnace is making an atypical noise, our friendly heating pros are here to assist with the best furnace repair in Front Royal, Virginia.

1. Furnace Making a Banging Noise

You might have a critical problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a couple of problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy as time passes, so that’s why it’s essential to schedule yearly furnace maintenance with Dave's Diversified Services. One of the things our professionals complete during this appointment is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise if ignition takes more time. The resulting gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can leak carbon monoxide, which is ordinarily released outdoors. This dangerous gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Dave's Diversified Services urges you to turn it off and contacting us at 540-636-3396. Excessive natural gas in your furnace or a ruptured heat exchanger are critical troubles that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move hot air throughout your home. If the ductwork wasn’t installed properly or is aging, it can make a lot of noise when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Get in touch with Dave's Diversified Services at 540-636-3396 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to operate on the right voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or chilly air throughout your residence, and a capacitor, which starts the motor. If either of these components are failing, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be the result of something small, like an unsecure screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and calling our heating specialists at 540-636-3396 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

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

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve examined your vents but are still hearing whistling, Dave's Diversified Services can provide support. It’s essential to get loose ductwork fixed fast, as it can make comfort troubles in your house and inflate your utility bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound frequently means there’s an issue with your furnace’s blower. Switch off your furnace off now and contact our pros at 540-636-3396 for help.
