1. Furnace Makes a Banging Sound

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

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s essential to set yearly furnace maintenance with Gopher Heating and Air Conditioning. One of the jobs our pros complete during this work 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 crack your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can discharge carbon monoxide, which is normally vented outdoors. 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 recommends turning it off and contacting us at 952-373-0377. Too much natural gas in your furnace or a broken heat exchanger are critical problems that necessitate fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air across your home. If the ductwork wasn’t put in right or is getting dated, it can be loud when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Contact Gopher Heating and Air Conditioning at 952-373-0377 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace depends on an internal transformer to work on the correct voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or chilly air around your rooms, and a capacitor, which starts the motor. If either of these parts are failing, 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 due to something little, like an unsecure screw, or something critical, like a broken component. In either case, we urge you to shut your furnace off and calling our heating specialists at 952-373-0377 for assistance.

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 needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubricated. We know that maintenance sometimes slips your mind, but our professionals can get your furnace operating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You may also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still noticing whistling, Gopher Heating and Air Conditioning can help. It’s essential to get loose ductwork fixed fast, since it can create comfort issues in your home and inflate your gas expenses.

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 trouble with your furnace’s blower. Shut down your furnace off now and reach our pros at 952-373-0377 for help.
