When your furnace is running properly, it should provide heat without making too much sound. While it’s common to catch your furnace making noise as it begins running, other disruptions are signaling your furnace should get immediate professional help.
Here are some of the most common furnace noises and what they could be indicating. If your furnace is making a strange noise, our friendly heating specialists are here to assist with the best furnace repair in Monroe, Wisconsin.
1. Furnace Making a Banging Noise
You might have a serious issue on your hands if you’re detecting 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 increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over time, so that’s why it’s critical to schedule routine furnace maintenance with Lanz Furnace and Fireplace. One of the jobs our professionals perform during this work is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise if ignition is delayed. The subsequent gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can discharge carbon monoxide, which is ordinarily vented outdoors. This hazardous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Lanz Furnace and Fireplace advises turning it off and contacting us at 608-291-3606. Too much natural gas in your furnace or a broken heat exchanger are critical troubles that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air around your residence. If the ductwork wasn’t installed properly or is getting dated, it can be noisy when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Lanz Furnace and Fireplace at 608-291-3606 and we’ll pinpoint 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 often indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the proper voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or chilly air across your home, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be the result of something small, like an unfastened screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and contacting our heating pros at 608-291-3606 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubricated. We are aware that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
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 running if a floor vent is loose. If you’ve checked your vents but are still noticing noise, Lanz Furnace and Fireplace can help. It’s important to get loose ductwork fixed without delay, since it can result in comfort troubles in your house and increase your heating bills.
6. Furnace Making a Grinding Noise
It’s not an encouraging 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. Switch off your furnace off now and contact us at 608-291-3606 for support.
