When your furnace is running correctly, it should provide warm air without generating too much disruption. While it’s normal to hear your furnace making noise as it turns on, other noises are showing your furnace should get immediate professional assistance.
Here are some of the most reported furnace noises and what they can be signaling. If your furnace is making an odd noise, our friendly heating pros are here to help with the best furnace repair in Jefferson, Wisconsin.
1. Furnace Makes a Banging Sound
You may have a serious problem on your hands if you’re hearing 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 increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy as time passes, so that’s why it’s important to set routine furnace maintenance with Pratt Brothers. One of the things our technicians complete during this work is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes more time. The subsequent gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can discharge carbon monoxide, which is ordinarily released outside. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Pratt Brothers recommends turning it off and reaching us at 920-347-8495. Excessive natural gas in your furnace or a ruptured heat exchanger are hazardous issues that necessitate fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air across your home. If the ductwork wasn’t installed right or is aging, it can make a lot of noise when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Pratt Brothers at 920-347-8495 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically means there’s an electrical issue, 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 isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or cold 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 Rattles
If your furnace is making a rattling noise, it could be related to something minor, like an unsecure screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 920-347-8495 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubricated. We are aware that maintenance often slips your mind, but our techs can get your furnace running quietly again fast.
5. Furnace Whistles
When you’re hearing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still hearing whistling, Pratt Brothers can provide support. It’s important to get loose ductwork fixed fast, as it can result in comfort troubles in your home and increase your utility costs.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Turn off your furnace off immediately and call our pros at 920-347-8495 for assistance.
