When your furnace is working properly, it should give heat without generating too much sound. While it’s normal to notice your furnace making noise as it begins running, other disruptions are indicating your furnace requires immediate professional help.
Here are some of the most common furnace noises and what they might mean. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in Pocatello, Idaho.
1. Furnace Making a Banging Noise
You may have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean 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 grimy as time passes, so that’s why it’s important to schedule routine furnace maintenance with Vogts Heating & Air. One of the jobs our professionals complete during this appointment is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can leak carbon monoxide, which is normally 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 ruptured heat exchanger are serious problems that necessitate immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver warm air around your house. If the ductwork wasn’t put in properly or is aging, it can be noisy when your furnace runs. This can be the problem 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 wait to call us. A buzzing sound often indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or cold air across your house, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be related to something little, like an unsecure screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 208-621-0129 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it requires 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 technicians can get your furnace running quietly again rapidly.
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 could also be aware of whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing sound, Vogts Heating & Air can assist you. It’s essential to get loose ductwork fixed without delay, since it can create comfort issues in your home and drive up your energy expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s a problem with your furnace’s blower. Switch off your furnace off promptly and contact our pros at 208-621-0129 for help.
