When your furnace is working correctly, it should give heat without generating too much disruption. While it’s expected 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 reported furnace noises and what they can be indicating. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Marshalltown, Iowa.
1. Furnace Making a Banging Noise
You might have an urgent situation 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 several problems. These include gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s critical to set seasonal furnace maintenance with Kapaun & Brown. One of the jobs our professionals complete during this work is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup might break your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can discharge carbon monoxide, which is regularly vented outside. This dangerous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Kapaun & Brown urges you to turn it off and contacting us at 641-812-2028. Too much natural gas in your furnace or a fractured heat exchanger are dangerous issues that necessitate prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide heated air across your residence. If the ductwork wasn’t installed correctly or is getting old, it can be loud when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Kapaun & Brown at 641-812-2028 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently means there’s an electrical problem, 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 is loose, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cooled air around your house, and a capacitor, which triggers the motor. If either of these components are fading, 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 due to something minor, like an unfastened screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at 641-812-2028 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to alert you it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be greased. We know that maintenance often slips your mind, but our technicians 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 frequently 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 noticing whistling, Kapaun & Brown can help. It’s essential to get loose ductwork repaired without delay, since it can create comfort problems in your residence and drive up your utility expenses.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise typically means there’s a problem with your furnace’s blower. Switch off your furnace off now and reach us at 641-812-2028 for support.
