When your furnace is running correctly, it should give warm air without making too much disruption. While it’s normal to catch your furnace making noise as it begins running, other disruptions are indicating your furnace needs immediate professional assistance.

Here are some of the most common furnace noises and what they could be signaling. If your furnace is making a weird noise, our friendly heating pros are here to fix the problem with the best furnace repair in Marshfield, Wisconsin.

1. Furnace Making a Banging Noise

You may have a serious problem 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 include gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy as time passes, so that’s why it’s important to book seasonal furnace maintenance with House of Heating Incorporated. One of the jobs our pros do 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 subsequent gas buildup might break your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can emit carbon monoxide, which is ordinarily vented outside. This toxic gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, House of Heating Incorporated urges you to turn it off and contacting us at 715-384-3163. Too much natural gas in your furnace or a cracked heat exchanger are serious problems that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide hot air throughout your house. If the ductwork wasn’t put in properly or is aging, it can make a lot of noise when your furnace is on. This might be the issue if your furnace makes a banging noise when it shuts off. Get in touch with House of Heating Incorporated at 715-384-3163 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to work on the right voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes hot or cold air around your residence, and a capacitor, which triggers 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 may be the result of something small, like an unfastened screw, or something critical, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating professionals at 715-384-3163 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance sometimes slips your mind, but our technicians can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also hear whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still hearing whistling, House of Heating Incorporated can assist you. It’s important to get loose ductwork taken care of quickly, because it can create comfort problems in your residence and inflate your gas costs.

6. Furnace Making a 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 reach us at 715-384-3163 for help.
