When your furnace is running properly, it should give warm air without generating too much noise. While it’s normal to catch your furnace making noise as it begins running, other disruptions are signaling your furnace requires immediate professional help.
Here are some of the most common furnace noises and what they could be signaling. If your furnace is making an odd noise, our friendly heating pros are here to help with the best furnace repair in Seymour, Wisconsin.
1. Furnace Making a Banging Noise
You could have an urgent issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a few problems. These include 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 annual furnace maintenance with Diedrick's Heating and Air Conditioning. One of the tasks our technicians do during this work is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can emit carbon monoxide, which is regularly emitted outside. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Diedrick's Heating and Air Conditioning urges you to turn it off and contacting us at 920-833-7967. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous problems that require prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air around your residence. If the ductwork wasn’t put in right or is getting dated, it can make a lot of noise when your furnace is on. This can be the problem if your furnace makes a banging noise when it shuts off. Call Diedrick's Heating and Air Conditioning at 920-833-7967 and we’ll figure out 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 typically indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the correct voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or chilly air throughout your residence, and a capacitor, which starts the motor. If either of these components 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 related to something little, like an unsecure screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 920-833-7967 for support.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubricated. We are aware that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again quickly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting 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 working if a floor vent is loose. If you’ve examined your vents but are still noticing sound, Diedrick's Heating and Air Conditioning can assist you. It’s critical to get loose ductwork repaired without delay, since it can create comfort troubles in your house and inflate your energy costs.
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 sound usually means there’s trouble with your furnace’s blower. Switch off your furnace off right away and reach our pros at 920-833-7967 for assistance.
