Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Monroe, Wisconsin.
1. Furnace Making a Banging Noise
You may have a serious issue 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 several problems. These include gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over the years, so that’s why it’s essential to schedule routine furnace maintenance with Lanz Furnace and Fireplace. One of the things our pros do during this service is clean your furnace’s burners. When this piece gets dirty, you could 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 changes into warmth. Any cracks in it can leak carbon monoxide, which is ordinarily released away from your home. This dangerous gas can be fatal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Lanz Furnace and Fireplace advises turning it off and reaching us at 608-291-3606. Excessive natural gas in your furnace or a cracked heat exchanger are critical problems that necessitate fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver heated air across your home. If the ductwork wasn’t put in properly or is aging, it can be noisy when your furnace runs. This could be the case if your furnace makes a banging noise when it shuts off. Call Lanz Furnace and Fireplace at 608-291-3606 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t wait 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 run on the correct voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or cold air throughout your residence, and a capacitor, which starts the motor. If either of these components are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be related to something minor, like a loose screw, or something serious, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 608-291-3606 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubricated. We are aware that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also hear whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still sensing sound, Lanz Furnace and Fireplace can provide support. It’s important to get loose ductwork fixed quickly, as it can make comfort issues in your house and inflate your heating expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound usually means there’s an issue with your furnace’s blower. Turn off your furnace off right away and contact our pros at 608-291-3606 for help.
