When your furnace is running correctly, it should deliver warm air without creating too much sound. While it’s normal 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 frequent furnace noises and what they can be indicating. If your furnace is making a weird noise, our friendly heating specialists are here to assist with the best furnace repair in Pocatello, Idaho.
1. Furnace Making a Banging Noise
You may have a serious situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a couple of problems. These range from gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s critical to book seasonal furnace maintenance with Vogts Heating & Air. One of the things our techs do during this work is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can discharge carbon monoxide, which is ordinarily released away from your home. This dangerous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Vogts Heating & Air urges you to turn it off and calling us at 208-621-0129. Too much natural gas in your furnace or a fractured heat exchanger are serious troubles that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air around your house. If the ductwork wasn’t put in properly or is getting dated, it can be noisy when your furnace is heating. This might be the problem if your furnace makes a banging noise when it shuts off. Contact Vogts Heating & Air at 208-621-0129 and we’ll pinpoint 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 often indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to work on the correct voltage. If wires or the box isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or cooled air across your residence, and a capacitor, which triggers 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 the result of something small, like an unsecure screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and calling our heating professionals at 208-621-0129 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to get your attention it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also be aware of whistling while the furnace is operating if a floor vent is loose. If you’ve looked at your vents but are still hearing sound, Vogts Heating & Air can provide support. It’s important to get loose ductwork fixed quickly, because it can make comfort problems in your home and drive up your utility bills.
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 racket typically means there’s trouble with your furnace’s blower. Switch off your furnace off instantly and contact us at 208-621-0129 for assistance.
