When your furnace is operating properly, it should provide warm air without generating too much noise. While it’s common to hear your furnace making noise as it begins running, other disruptions are indicating your furnace should get immediate professional support.
Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making an atypical noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Chelan and Wenatchee, Washington.
1. Furnace Making a Banging Noise
You could have a critical problem 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 couple of problems. These include gas building up 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 essential to book yearly furnace maintenance with Lakeside Heating & Air. One of the things our pros complete during this work is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can emit carbon monoxide, which is regularly released outdoors. This hazardous gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Lakeside Heating & Air recommends turning it off and calling us at 509-284-4265. Excessive natural gas in your furnace or a fractured heat exchanger are hazardous problems that require fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide warm air throughout your house. If the ductwork wasn’t designed right or is aging, it can make a lot of noise when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Call Lakeside Heating & Air at 509-284-4265 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical situation, 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 might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or cooled air across your home, and a capacitor, which triggers the motor. If either of these components are failing, 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 little, like an unsecure screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and calling our heating specialists at 509-284-4265 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to alert you it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubricated. We realize that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still sensing sound, Lakeside Heating & Air can assist you. It’s critical to get loose ductwork taken care of fast, since it can result in comfort troubles in your house and increase your energy expenses.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Turn off your furnace off now and reach us at 509-284-4265 for assistance.
