When your furnace is running properly, it should give heat without generating too much noise. While it’s common to notice your furnace making noise as it starts up, other disruptions are indicating your furnace needs immediate professional help.
Here are some of the most common furnace noises and what they could mean. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Holdrege, Nebraska.
1. Furnace Makes a Banging Sound
You may have a critical problem on your hands if you’re hearing 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 accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over the years, so that’s why it’s critical to schedule routine furnace maintenance with Durable Service. One of the things our pros perform during this appointment is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup might crack your furnace’s heat exchanger, where natural gas turns into heat. Any fractures in it can discharge carbon monoxide, which is regularly vented away from your home. This toxic gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Durable Service advises turning it off and reaching us at 308-995-8177. Excessive natural gas in your furnace or a fractured heat exchanger are critical troubles that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide hot air around your home. If the ductwork wasn’t installed correctly or is getting old, it can be noisy when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Durable Service at 308-995-8177 and we’ll pinpoint the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or cooled air throughout your space, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace turns on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it could be the result of 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 308-995-8177 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubricated. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace operating quietly again fast.
5. Furnace Whistles
When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also hear whistling while the furnace is working if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, Durable Service can help. It’s essential to get loose ductwork taken care of without delay, since it can create comfort troubles in your residence and inflate your energy costs.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not an encouraging 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 right away and contact our professionals at 308-995-8177 for help.
