When your furnace is working properly, it should provide warm air without creating too much noise. While it’s expected to catch your furnace making noise as it turns on, other noises are signaling your furnace requires immediate professional support.
Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making an odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Cedar Rapids.
1. Furnace Making a Banging Noise
You might 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 a few problems. These include gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s essential to book annual furnace maintenance with Ilten's Incorporated. One of the things our professionals complete during this appointment is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The subsequent gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can emit carbon monoxide, which is regularly vented away from your home. This toxic gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Ilten's Incorporated advises turning it off and calling us at 319-208-3295. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous troubles that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move warm air across your home. If the ductwork wasn’t put in properly or is aging, it can make a lot of noise when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Call Ilten's Incorporated at 319-208-3295 and we’ll determine 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 typically indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or cold air throughout your residence, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something small, like an unsecure screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 319-208-3295 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 neglected furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubed. We realize that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing 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 on if a floor vent is loose. If you’ve checked your vents but are still noticing sound, Ilten's Incorporated can help. It’s essential to get loose ductwork taken care of quickly, since it can make comfort troubles in your residence and inflate your gas expenses.
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 racket often means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and call our pros at 319-208-3295 for assistance.
