When your furnace is working like it should, it should give heat without making too much sound. While it’s normal to catch your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional support.
Here are some of the most reported furnace noises and what they can mean. If your furnace is making an odd noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Bartlesville, Oklahoma.
1. Furnace Makes Banging or Knocking Sounds
You may have a serious situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a few problems. These include gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over the years, so that’s why it’s critical to schedule seasonal furnace maintenance with Farris Heating & Air. One of the things our pros do during this service is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can discharge carbon monoxide, which is regularly emitted outdoors. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Farris Heating & Air recommends turning it off and reaching us at 918-333-0376. Excessive natural gas in your furnace or a ruptured heat exchanger are critical problems that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move hot air around your house. If the ductwork wasn’t installed properly or is getting dated, it can make a lot of noise when your furnace is on. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Farris Heating & Air at 918-333-0376 and we’ll figure out the problem.
2. Furnace Buzzes Constantly
If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the right voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cold air throughout your space, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be the result of something little, like a loose screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating professionals at 918-333-0376 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 forgotten furnace maintenance the past few years, belts could be worn down or a bearing might need to be greased. We realize that maintenance often slips your mind, but our technicians can get your furnace operating quietly again fast.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve checked your vents but are still noticing sound, Farris Heating & Air can provide support. It’s essential to get loose ductwork fixed fast, as it can make comfort issues in your home and inflate your energy expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a positive 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. Shut down your furnace off immediately and reach our professionals at 918-333-0376 for help.
