When your furnace is running correctly, it should deliver warm air without making too much noise. While it’s common to catch your furnace making noise as it turns on, other disruptions are signaling your furnace should get immediate professional assistance.
Here are some of the most reported furnace noises and what they could mean. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Wyandotte, Michigan .
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 signal there could be several problems. These involve gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over the years, so that’s why it’s essential to schedule annual furnace maintenance with Gee & Missler Heating & Air Conditioning. One of the jobs our techs perform during this service is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can leak carbon monoxide, which is normally released outside. This hazardous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Gee & Missler Heating & Air Conditioning recommends turning it off and reaching us at 734-284-1224. Too much natural gas in your furnace or a fractured heat exchanger are dangerous problems that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver warm air across your residence. If the ductwork wasn’t designed right or is aging, it can be noisy when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Gee & Missler Heating & Air Conditioning at 734-284-1224 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 typically means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the proper voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or chilly air throughout your rooms, 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 could be due to something small, like an unfastened screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 734-284-1224 for help.
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 making an effort to alert you it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubed. We are aware that maintenance sometimes slips your mind, but our pros can get your furnace heating quietly again rapidly.
5. Furnace Whistles
When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also hear whistling while the furnace is on if a floor vent is loose. If you’ve examined your vents but are still sensing sound, Gee & Missler Heating & Air Conditioning can assist you. It’s important to get loose ductwork repaired without delay, since it can make comfort problems in your house and inflate your utility costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket often means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and reach our pros at 734-284-1224 for help.
