When your furnace is running like it should, it should deliver warm air without generating too much disruption. While it’s normal to notice your furnace making noise as it begins running, other noises are showing your furnace needs immediate professional assistance.

Here are some of the most frequent furnace noises and what they might be signaling. If your furnace is making an atypical noise, our friendly heating specialists are here to assist with the best furnace repair in Savage, Minnesota.

1. Furnace Making a Banging Noise

You might have a serious situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a few problems. These involve gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy as time passes, so that’s why it’s critical to schedule routine furnace maintenance with Gopher Heating and Air Conditioning. One of the tasks our pros perform during this work is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise after ignition is delayed. The subsequent gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can emit carbon monoxide, which is ordinarily released away from your home. This dangerous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Gopher Heating and Air Conditioning urges you to turn it off and calling us at 952-373-0377. Significant natural gas in your furnace or a cracked heat exchanger are serious problems that require fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move warm air around your house. If the ductwork wasn’t designed correctly or is getting old, it can be noisy when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Gopher Heating and Air Conditioning at 952-373-0377 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or chilly air across your house, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be due to something minor, like an unfastened screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at 952-373-0377 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to get your attention it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing might need to be greased. We know that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve looked at your vents but are still sensing whistling, Gopher Heating and Air Conditioning can assist you. It’s critical to get loose ductwork taken care of quickly, as it can create comfort problems in your home and inflate your heating expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket usually means there’s a problem with your furnace’s blower. Shut down your furnace off right away and reach us at 952-373-0377 for support.
