1. Furnace Making a Banging Noise
You may have a serious situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These include gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s essential to schedule seasonal furnace maintenance with McFadden Heating & Cooling. One of the jobs our professionals complete during this service is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can discharge carbon monoxide, which is ordinarily emitted outdoors. This toxic gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, McFadden Heating & Cooling advises turning it off and reaching us at 1-866-781-0111. Excessive natural gas in your furnace or a cracked heat exchanger are critical issues that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move warm air throughout your house. If the ductwork wasn’t installed properly or is getting dated, it can be noisy when your furnace is heating. This might be the case if your furnace makes a banging noise when it shuts off. Contact McFadden Heating & Cooling at 1-866-781-0111 and we’ll figure out 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 often is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cooled air across your rooms, and a capacitor, which starts the motor. If either of these components 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 due to something small, like an unsecure screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 1-866-781-0111 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 get your attention it requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing may need to be greased. We realize that maintenance sometimes slips your mind, but our professionals can get your furnace running quietly again rapidly.
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 could also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still sensing sound, McFadden Heating & Cooling can provide support. It’s important to get loose ductwork fixed fast, as it can create comfort issues in your home and inflate your heating bills.
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 frequently means there’s an issue with your furnace’s blower. Shut down your furnace off right away and call us at 1-866-781-0111 for help.
