1. Furnace Making a Banging Noise
You might have a critical situation 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 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 dirty over time, so that’s why it’s critical to schedule routine furnace maintenance with Home Furniture, Plumbing & Heating. One of the things our pros do during this service is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup might crack your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can leak carbon monoxide, which is ordinarily emitted away from your home. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Home Furniture, Plumbing & Heating urges you to turn it off and contacting us at 815-933-8213. Too much natural gas in your furnace or a cracked heat exchanger are serious issues that should get immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide heated air throughout your house. If the ductwork wasn’t put in correctly or is getting dated, it can be loud when your furnace runs. This may be the issue if your furnace makes a banging noise when it shuts off. Call Home Furniture, Plumbing & Heating at 815-933-8213 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cold air around your house, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace turns on.
3. Furnace Rattles
If your furnace is making a rattling noise, it may be due to something minor, like an unsecure screw, or something major, like a broken part. In either case, we advise shutting your furnace off and calling our heating specialists at 815-933-8213 for assistance.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the last couple of 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 heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still hearing whistling, Home Furniture, Plumbing & Heating can help. It’s important to get loose ductwork repaired quickly, because it can make comfort troubles in your residence and inflate your heating costs.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal racket usually means there’s an issue with your furnace’s blower. Turn off your furnace off now and reach our pros at 815-933-8213 for support.
