When your furnace is working properly, it should give warmth without making too much noise. While it’s normal to catch your furnace making noise as it begins running, other disruptions are signaling your furnace should get immediate professional support.
Here are some of the most reported furnace noises and what they can mean. If your furnace is making an atypical noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Rockford, Illinois.
1. Furnace Making a Banging Noise
You might 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 may indicate there could be several problems. These involve gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty as time passes, so that’s why it’s essential to set yearly furnace maintenance with Temperature Doctors Heating & Cooling. One of the tasks our professionals perform during this work is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup can break your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can leak carbon monoxide, which is ordinarily emitted away from your home. This hazardous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Temperature Doctors Heating & Cooling advises turning it off and contacting us at (815) 914-6197. Significant natural gas in your furnace or a broken heat exchanger are dangerous problems that necessitate prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide warm air around your residence. If the ductwork wasn’t designed right or is getting old, it can be loud when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Temperature Doctors Heating & Cooling at (815) 914-6197 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the proper voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or cold air across your home, and a capacitor, which starts the motor. If either of these components are failing, 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 due to something minor, like a loose screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and contacting our heating professionals at (815) 914-6197 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to tell you it requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing could need to be greased. We realize that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still noticing noise, Temperature Doctors Heating & Cooling can help. It’s essential to get loose ductwork fixed quickly, because it can create comfort issues in your residence and increase your utility costs.
6. Furnace Making a Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal noise often means there’s trouble with your furnace’s blower. Turn off your furnace off now and reach our professionals at (815) 914-6197 for support.
