When your furnace is running correctly, it should deliver warm air without generating too much noise. While it’s expected to hear your furnace making noise as it turns on, other sounds are showing your furnace needs immediate professional help.
Here are some of the most reported furnace noises and what they can mean. If your furnace is making an atypical noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Pocatello, Idaho.
1. Furnace Makes Banging or Knocking Sounds
You may have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a few problems. These range from gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty as time passes, so that’s why it’s important to schedule annual furnace maintenance with Vogts Heating & Air. One of the things our professionals complete during this service is clean your furnace’s burners. When this part gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can leak carbon monoxide, which is normally released outdoors. This dangerous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Vogts Heating & Air recommends turning it off and contacting us at 208-621-0129. Too much natural gas in your furnace or a ruptured heat exchanger are hazardous troubles that should get immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air around your residence. If the ductwork wasn’t installed right or is getting old, it can make a lot of noise when your furnace is heating. 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 figure out the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t delay calling 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 correct voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or chilly air around your rooms, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it can be due to something minor, like a loose screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists 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 get your attention it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubed. We are aware 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 the result of an air leak in your ductwork. You might also hear whistling while the furnace is running if a floor vent is loose. If you’ve examined your vents but are still sensing whistling, Vogts Heating & Air can provide support. It’s important to get loose ductwork repaired without delay, as it can make comfort problems in your home and drive up your energy bills.
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 noise frequently means there’s trouble with your furnace’s blower. Switch off your furnace off instantly and call our professionals at 208-621-0129 for assistance.
