When your furnace is operating properly, it should deliver heat without generating too much sound. While it’s expected to hear your furnace making noise as it starts up, other noises are indicating your furnace needs immediate professional help.

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

1. Furnace Makes Banging or Knocking Sounds

You may have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over the years, so that’s why it’s critical to set routine furnace maintenance with Gopher Heating and Air Conditioning. One of the things our techs do during this appointment is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can leak carbon monoxide, which is regularly vented outside. This dangerous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Gopher Heating and Air Conditioning urges you to turn it off and reaching us at 952-373-0377. Too much natural gas in your furnace or a cracked heat exchanger are hazardous troubles that should get immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move heated air throughout your home. If the ductwork wasn’t designed right or is aging, 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. Contact 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 means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box isn’t tight enough, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or chilly air across your home, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be the result of something small, like an unfastened screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and calling our heating pros at 952-373-0377 for help.

4. Furnace Making a Squealing Noise

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

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is operating if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing whistling, Gopher Heating and Air Conditioning can assist you. It’s essential to get loose ductwork taken care of fast, since it can make comfort problems in your residence and increase your heating bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise frequently means there’s a problem with your furnace’s blower. Turn off your furnace off instantly and call us at 952-373-0377 for help.
