When your furnace is running correctly, it should provide warm air without generating too much disruption. While it’s normal to notice your furnace making noise as it starts up, other noises are indicating your furnace needs immediate professional assistance.

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

1. Furnace Making a Banging Noise

You could 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 may indicate there could be a few problems. These range from gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s critical to set seasonal furnace maintenance with Gopher Heating and Air Conditioning. One of the jobs our professionals perform during this appointment is clean your furnace’s burners. When this part gets grimy, you could 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 heat. Any cracks in it can emit carbon monoxide, which is normally emitted outside. This toxic gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Gopher Heating and Air Conditioning advises turning it off and calling us at 952-373-0377. Significant natural gas in your furnace or a ruptured heat exchanger are dangerous issues that require prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide warm air around your home. If the ductwork wasn’t put in right or is getting dated, it can be loud when your furnace is heating. This can be the issue 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 determine 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 typically is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the right 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 has a blower motor, which distributes heated or cold air across your house, and a capacitor, which turns on the motor. If either of these components are failing, they will buzz when the furnace switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be related to something small, like an unsecure screw, or something serious, like a broken piece. In either case, we recommend shutting off your furnace and calling our heating professionals at 952-373-0377 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying 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 could need to be greased. We are aware that maintenance frequently slips your mind, but our pros can get your furnace running quietly again fast.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You might also hear whistling while the furnace is working if a floor vent is loose. If you’ve examined your vents but are still hearing noise, Gopher Heating and Air Conditioning can assist you. It’s critical to get loose ductwork taken care of without delay, as it can make comfort problems in your home and increase your energy costs.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Switch off your furnace off instantly and call us at 952-373-0377 for assistance.
