1. Furnace Making a Banging Noise
You could have a serious situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These involve gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over time, so that’s why it’s critical to set yearly furnace maintenance with KDM Service Corporation. One of the things our technicians complete during this appointment is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup might break your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can discharge carbon monoxide, which is ordinarily released outside. This hazardous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, KDM Service Corporation urges you to turn it off and reaching us at 205-208-8090. Excessive natural gas in your furnace or a ruptured heat exchanger are critical issues that require immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide warm air around your house. If the ductwork wasn’t installed properly or is getting old, it can be noisy when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Get in touch with KDM Service Corporation at 205-208-8090 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box isn’t tight enough, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or chilly air throughout your home, and a capacitor, which starts the motor. If either of these pieces are failing, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it might be the result of something minor, like an unfastened screw, or something serious, like a broken component. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 205-208-8090 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 get your attention it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubed. We are aware that maintenance frequently slips your mind, but our pros can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You might also hear whistling while the furnace is operating if a floor vent is loose. If you’ve looked at your vents but are still sensing whistling, KDM Service Corporation can assist you. It’s critical to get loose ductwork repaired fast, because it can create comfort troubles in your home and increase your heating costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound often means there’s a problem with your furnace’s blower. Switch off your furnace off promptly and call us at 205-208-8090 for help.
