When your furnace is operating correctly, it should deliver heat without generating too much disruption. While it’s common to catch your furnace making noise as it begins running, other noises are showing your furnace requires immediate professional help.
Here are some of the most frequent furnace noises and what they could mean. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Chelan and Wenatchee, Washington.
1. Furnace Making a Banging Noise
You may have a serious problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These include gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy over the years, so that’s why it’s important to book yearly furnace maintenance with Lakeside Heating & Air. One of the tasks our technicians do during this service is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The resulting gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can discharge carbon monoxide, which is regularly released outside. This dangerous gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Lakeside Heating & Air urges you to turn it off and contacting us at 509-284-4265. Too much natural gas in your furnace or a ruptured heat exchanger are hazardous issues that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver heated air throughout your home. If the ductwork wasn’t installed correctly or is getting dated, it can be loud when your furnace is on. This could be the issue if your furnace makes a banging noise when it shuts off. Call Lakeside Heating & Air at 509-284-4265 and we’ll pinpoint the problem.
2. Furnace Buzzes Constantly
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically means there’s an electrical situation, 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 needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or chilly air around your home, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace switches on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it may be related to something small, like a loose screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 509-284-4265 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to alert you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubed. We realize that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again quickly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re hearing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may also hear whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still sensing noise, Lakeside Heating & Air can assist you. It’s critical to get loose ductwork taken care of without delay, as it can create comfort troubles in your residence and drive up your utility costs.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a good sign if you hear 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 now and call our professionals at 509-284-4265 for support.
