When your furnace is running correctly, it should give heat without generating too much noise. While it’s common to hear your furnace making noise as it begins running, other sounds are showing your furnace requires immediate professional support.
Here are some of the most reported furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Pocatello, Idaho.
1. Furnace Makes Banging or Knocking Sounds
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 a couple of problems. These include gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over time, so that’s why it’s essential to set seasonal furnace maintenance with Vogts Heating & Air. One of the tasks our pros complete during this appointment is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can emit carbon monoxide, which is ordinarily released away from your home. This toxic gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Vogts Heating & Air recommends turning it off and calling us at 208-621-0129. Excessive natural gas in your furnace or a fractured heat exchanger are critical troubles that necessitate fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air across your residence. If the ductwork wasn’t designed right or is getting old, it can make a lot of noise when your furnace runs. This may be the issue 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 pinpoint the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or chilly air across your house, and a capacitor, which starts the motor. If either of these components are failing, they will buzz when the furnace switches on.
3. Furnace Rattles
If your furnace is making a rattling noise, it may be the result of something minor, 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 208-621-0129 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to get your attention it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing might need to be greased. We realize that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing noise, Vogts Heating & Air can assist you. It’s important to get loose ductwork taken care of fast, since it can result in comfort problems in your residence and increase your utility costs.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s trouble with your furnace’s blower. Switch off your furnace off right away and call our professionals at 208-621-0129 for assistance.
