1. Furnace Making a Banging Noise
You may have a critical issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These involve gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over time, so that’s why it’s essential to book routine furnace maintenance with Anderson Heating & A/C. One of the things our techs do during this appointment is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can emit carbon monoxide, which is normally vented outdoors. This toxic gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Anderson Heating & A/C urges you to turn it off and reaching us at 775-230-7628. Excessive natural gas in your furnace or a broken heat exchanger are hazardous troubles that require prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver heated air throughout your residence. If the ductwork wasn’t designed right or is getting dated, it can be loud when your furnace is heating. This can be the case if your furnace makes a banging noise when it shuts off. Get in touch with Anderson Heating & A/C at 775-230-7628 and we’ll figure out 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 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 could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or chilly air throughout your house, and a capacitor, which triggers the motor. If either of these parts are going out, 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 the result of something minor, like an unfastened screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating pros at 775-230-7628 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to get your attention it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing could need to be lubed. We know that maintenance often slips your mind, but our professionals 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 might also be aware of whistling while the furnace is running if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, Anderson Heating & A/C can provide support. It’s critical to get loose ductwork repaired quickly, since it can result in comfort troubles in your home and inflate your gas expenses.
6. Furnace Making a Grinding Noise
It’s not a positive 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. Shut down your furnace off immediately and call our pros at 775-230-7628 for assistance.
