Here are some of the most reported furnace noises and what they might 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 Morgantown, West Virginia.
1. Furnace Makes a Banging Sound
You might have a serious situation 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 involve gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy as time passes, so that’s why it’s critical to schedule yearly furnace maintenance with Mountain Air. One of the things our professionals do during this work is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can discharge carbon monoxide, which is regularly released outside. This hazardous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Mountain Air urges you to turn it off and contacting us at 304-413-1287. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous problems that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide hot air around your residence. If the ductwork wasn’t put in correctly or is aging, it can make a lot of noise when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Contact Mountain Air at 304-413-1287 and we’ll figure out the problem.
2. Furnace Buzzes Constantly
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the correct 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 uses a blower motor, which moves heated or chilly air throughout your residence, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Rattles
If your furnace is making a rattling noise, it could be related to something small, like an unsecure screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating professionals at 304-413-1287 for support.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing might need to be greased. We realize that maintenance sometimes slips your mind, but our professionals can get your furnace running quietly again quickly.
5. Furnace Whistles
When you’re hearing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also hear whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still noticing noise, Mountain Air can help. It’s essential to get loose ductwork fixed without delay, since it can make comfort problems in your house and drive up your utility expenses.
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 sound typically means there’s an issue with your furnace’s blower. Turn off your furnace off right away and contact our professionals at 304-413-1287 for help.
