When your furnace is operating like it should, it should give warm air without making too much sound. While it’s expected to hear your furnace making noise as it starts up, other disruptions are signaling your furnace requires immediate professional assistance.
Here are some of the most frequent furnace noises and what they can mean. If your furnace is making a weird noise, our friendly heating professionals are here to assist with the best furnace repair in Moline, Illinois.
1. Furnace Making a Banging Noise
You might have a serious issue 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 range from gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over the years, so that’s why it’s critical to set routine furnace maintenance with Freed Heating & Air Conditioning. One of the jobs our technicians complete 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 ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can emit carbon monoxide, which is regularly emitted outside. This hazardous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Freed Heating & Air Conditioning advises turning it off and contacting us at 309-323-9584. Excessive natural gas in your furnace or a ruptured heat exchanger are dangerous issues that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move heated air across your home. If the ductwork wasn’t installed correctly or is getting dated, it can be noisy when your furnace is on. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Freed Heating & Air Conditioning at 309-323-9584 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently indicates an electrical issue, 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 needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or chilly air throughout your residence, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be the result of something little, like an unsecure screw, or something major, like a broken part. In either case, we advise shutting your furnace off and contacting our heating pros at 309-323-9584 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying 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 are aware that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also hear whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing sound, Freed Heating & Air Conditioning can assist you. It’s essential to get loose ductwork repaired without delay, since it can result in comfort troubles in your home and increase your heating bills.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise often means there’s a problem with your furnace’s blower. Shut down your furnace off right away and contact our professionals at 309-323-9584 for assistance.
