When your furnace is working correctly, it should give heat without generating too much sound. While it’s common to catch your furnace making noise as it begins running, other disruptions are signaling your furnace should get immediate professional assistance.
Here are some of the most reported furnace noises and what they might be indicating. If your furnace is making a strange noise, our friendly heating pros are here to fix the problem with the best furnace repair in Bartlesville, Oklahoma.
1. Furnace Makes a Banging Sound
You may 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 mean there could be a couple of problems. These range from gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy as time passes, so that’s why it’s essential to schedule annual furnace maintenance with Farris Heating & Air. One of the things our techs do during this appointment is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can discharge carbon monoxide, which is ordinarily vented outdoors. This dangerous gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Farris Heating & Air recommends turning it off and contacting us at 918-333-0376. Too much natural gas in your furnace or a ruptured heat exchanger are hazardous problems that necessitate prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move warm air around your house. If the ductwork wasn’t installed right or is getting dated, it can make a lot of noise when your furnace is on. This could be the issue if your furnace makes a banging noise when it shuts off. Call Farris Heating & Air at 918-333-0376 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the right voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or chilly air across your residence, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be the result of something small, like an unsecure screw, or something serious, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating pros at 918-333-0376 for help.
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 making an effort to tell you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubed. We know that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again quickly.
5. Furnace Whistles
When you’re hearing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may also notice whistling while the furnace is on if a floor vent is loose. If you’ve looked at your vents but are still noticing whistling, Farris Heating & Air can help. It’s critical to get loose ductwork repaired without delay, as it can make comfort troubles in your house and inflate your energy costs.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket typically means there’s an issue with your furnace’s blower. Shut down your furnace off immediately and reach our pros at 918-333-0376 for support.
