When your furnace is working correctly, it should deliver warmth without creating too much disruption. While it’s normal to notice your furnace making noise as it begins running, other disruptions are signaling your furnace needs immediate professional help.
Here are some of the most reported furnace noises and what they can be signaling. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in Pocatello, Idaho.
1. Furnace Makes a Banging Sound
You might have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be several problems. These involve gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over time, so that’s why it’s important to set routine furnace maintenance with Vogts Heating & Air. One of the tasks our techs complete during this appointment is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise when ignition takes more time. The resulting gas buildup might break your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can discharge carbon monoxide, which is regularly vented away from your home. This toxic gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Vogts Heating & Air urges you to turn it off and contacting us at 208-621-0129. Too much natural gas in your furnace or a fractured heat exchanger are hazardous problems that require immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide warm air across your home. If the ductwork wasn’t put in correctly or is getting dated, it can make a lot of noise when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Vogts Heating & Air at 208-621-0129 and we’ll determine 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 usually indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or chilly air around your house, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace turns on.
3. Furnace Rattles
If your furnace is making a rattling noise, it may be related to something small, like a loose screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating pros at 208-621-0129 for support.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to alert you it could use some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubed. We know that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still noticing whistling, Vogts Heating & Air can provide support. It’s important to get loose ductwork taken care of quickly, since it can result in comfort troubles in your residence and drive up your energy expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Switch off your furnace off promptly and contact our pros at 208-621-0129 for help.
