When your furnace is working correctly, it should give warmth without creating too much disruption. While it’s expected to hear your furnace making noise as it turns on, other disruptions are signaling your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Huntingburg, Indiana.

1. Furnace Making a Banging Noise

You might have a serious problem 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 a few problems. These include gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over time, so that’s why it’s essential to set seasonal furnace maintenance with Dearing's Service & Solutions. One of the things our technicians do during this appointment is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can emit carbon monoxide, which is regularly released outside. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Dearing's Service & Solutions urges you to turn it off and calling us at 812-200-5844. Too much natural gas in your furnace or a ruptured heat exchanger are dangerous problems that should get prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide warm air across your house. If the ductwork wasn’t put in right or is getting dated, it can be loud when your furnace is on. This could be the problem if your furnace makes a banging noise when it shuts off. Contact Dearing's Service & Solutions at 812-200-5844 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace uses an internal transformer to run on the right voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cold air around your space, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be due to something small, like an unfastened screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 812-200-5844 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to tell you it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing may need to be lubed. We know that maintenance frequently slips your mind, but our pros can get your furnace operating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You might also notice whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still noticing whistling, Dearing's Service & Solutions can assist you. It’s essential to get loose ductwork repaired fast, because it can result in comfort troubles in your home and inflate your gas expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound frequently means there’s a problem with your furnace’s blower. Shut down your furnace off right away and call our pros at 812-200-5844 for help.
