When your furnace is working correctly, it should give heat without creating too much sound. While it’s normal to notice your furnace making noise as it starts up, other disruptions are signaling your furnace requires immediate professional assistance.

Here are some of the most reported furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in West Jefferson, Ohio.

1. Furnace Makes a Banging Sound

You could have an urgent situation 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 include gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over the years, so that’s why it’s essential to schedule yearly furnace maintenance with West Jefferson Plumbing and Heating, Inc.. One of the tasks our techs complete during this appointment is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas turns into heat. Any fractures in it can leak carbon monoxide, which is regularly released outside. This hazardous gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, West Jefferson Plumbing and Heating, Inc. urges you to turn it off and contacting us at 614-879-9091. Significant natural gas in your furnace or a ruptured heat exchanger are serious problems that necessitate prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air across your home. If the ductwork wasn’t designed right or is getting dated, it can be noisy when your furnace runs. This may be the issue if your furnace makes a banging noise when it shuts off. Call West Jefferson Plumbing and Heating, Inc. at 614-879-9091 and we’ll determine the problem.

2. Furnace Buzzes Constantly

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

Your furnace depends on an internal transformer to work on the right voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or cooled air around your house, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something little, like an unfastened screw, or something major, like a broken component. In either case, we advise shutting your furnace off and contacting our heating specialists at 614-879-9091 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to alert you it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubricated. We know that maintenance often slips your mind, but our technicians can get your furnace operating 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 because of 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 examined your vents but are still sensing sound, West Jefferson Plumbing and Heating, Inc. can help. It’s essential to get loose ductwork fixed without delay, since it can result in comfort troubles in your house and inflate your utility expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s a problem with your furnace’s blower. Switch off your furnace off promptly and call our professionals at 614-879-9091 for help.
