When your furnace is working like it should, it should provide warmth without creating too much disruption. While it’s normal to catch your furnace making noise as it starts up, other disruptions are indicating your furnace requires immediate professional support.
Here are some of the most common furnace noises and what they can mean. If your furnace is making a strange noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Mount Hope, West Virginia.
1. Furnace Makes a Banging Sound
You might have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These include gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over time, so that’s why it’s important to schedule annual furnace maintenance with Appalachian Heating. One of the tasks our techs 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 more time. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can discharge carbon monoxide, which is ordinarily released away from your home. This dangerous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Appalachian Heating advises turning it off and contacting us at 304-707-0600. Significant natural gas in your furnace or a broken heat exchanger are serious troubles that should get fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air throughout your house. If the ductwork wasn’t installed right or is getting dated, it can be noisy when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Contact Appalachian Heating at 304-707-0600 and we’ll pinpoint the problem.
2. Furnace Makes a Buzzing Sound
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or chilly air around your house, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be related to something small, like an unsecure screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at 304-707-0600 for assistance.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to get your attention it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance often slips your mind, but our professionals can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You could also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, Appalachian Heating can assist you. It’s critical to get loose ductwork taken care of quickly, as it can result in comfort troubles in your house and increase your gas expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Switch off your furnace off right away and call our pros at 304-707-0600 for help.
