1. Furnace Making a Banging Noise
You may have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be several problems. These include gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy as time passes, so that’s why it’s important to set seasonal furnace maintenance with Jett's Heating & Air Inc.. One of the tasks our professionals 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 if ignition takes longer than normal. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can discharge carbon monoxide, which is ordinarily released outdoors. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Jett's Heating & Air Inc. urges you to turn it off and calling us at 815-410-1128. Significant natural gas in your furnace or a fractured heat exchanger are serious issues that necessitate fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move warm air across your residence. If the ductwork wasn’t installed properly or is getting old, it can make a lot of noise when your furnace is heating. This might be the problem if your furnace makes a banging noise when it shuts off. Call Jett's Heating & Air Inc. at 815-410-1128 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
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 depends on an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or chilly air throughout your house, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it might be the result of something small, like an unfastened screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating pros at 815-410-1128 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to get your attention it requires 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 are aware that maintenance often slips your mind, but our pros 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 likely the result of an air leak in your ductwork. You may also hear whistling while the furnace is working if a floor vent isn’t tight. If you’ve checked your vents but are still hearing whistling, Jett's Heating & Air Inc. can provide support. It’s essential to get loose ductwork fixed quickly, because it can create comfort troubles in your house and increase your utility bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket usually means there’s a problem with your furnace’s blower. Turn off your furnace off promptly and call our professionals at 815-410-1128 for support.
