1. Furnace Making a Banging Noise
You could have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These range from gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s critical to schedule routine furnace maintenance with Integrity AC & Heating LLC. One of the jobs our professionals complete during this work is clean your furnace’s burners. When this part gets grubby, you might hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can discharge carbon monoxide, which is normally vented outside. This toxic gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Integrity AC & Heating LLC advises turning it off and reaching us at 602-971-0567. Significant natural gas in your furnace or a broken heat exchanger are serious issues that require fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver warm air around your house. If the ductwork wasn’t designed properly or is aging, it can be loud when your furnace is on. This might be the issue if your furnace makes a banging noise when it shuts off. Call Integrity AC & Heating LLC at 602-971-0567 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 indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or cooled air around your house, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be due to something little, 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 specialists at 602-971-0567 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to get your attention it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubricated. We realize that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You may also hear whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still hearing noise, Integrity AC & Heating LLC can assist you. It’s critical to get loose ductwork repaired quickly, since it can result in comfort problems in your home and inflate your energy bills.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal noise typically means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and call us at 602-971-0567 for support.
