When your furnace is running correctly, it should deliver warm air without creating too much noise. While it’s normal to catch your furnace making noise as it starts up, other disruptions are indicating your furnace requires immediate professional assistance.
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 specialists are here to assist with the best furnace repair in Omaha, Nebraska.
1. Furnace Making a Banging Noise
You could have a serious 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 several problems. These include gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy as time passes, so that’s why it’s critical to schedule annual furnace maintenance with The Frazier Company. One of the tasks our technicians complete during this service is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes more time. The subsequent gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can discharge carbon monoxide, which is regularly vented away from your home. This hazardous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, The Frazier Company advises turning it off and reaching us at 402-628-0206. Excessive natural gas in your furnace or a fractured heat exchanger are hazardous troubles that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air throughout your home. If the ductwork wasn’t installed properly or is getting old, it can be noisy when your furnace is heating. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with The Frazier Company at 402-628-0206 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or cooled air throughout your residence, and a capacitor, which turns on the motor. If either of these parts 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 minor, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating specialists at 402-628-0206 for support.
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 needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubricated. We know that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again fast.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You may also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still hearing whistling, The Frazier Company can assist you. It’s essential to get loose ductwork fixed fast, as it can create comfort problems in your residence and increase your utility bills.
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 racket typically means there’s trouble with your furnace’s blower. Shut down your furnace off promptly and contact us at 402-628-0206 for assistance.
