1. Furnace Making a Banging Noise
You might have an urgent problem 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 couple of problems. These range from gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty as time passes, so that’s why it’s important to set seasonal furnace maintenance with Precision Mechanical. One of the tasks our pros do during this service is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup might crack your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can discharge carbon monoxide, which is regularly released away from your home. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Precision Mechanical advises turning it off and reaching us at 605-206-3766. Significant natural gas in your furnace or a cracked heat exchanger are critical problems that require immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide hot air around your home. If the ductwork wasn’t designed right or is getting old, it can be noisy when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Precision Mechanical at 605-206-3766 and we’ll pinpoint 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 typically means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box is loose, you might detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or chilly air around your house, and a capacitor, which starts the motor. If either of these components 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 might be the result of something small, like an unsecure screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating specialists at 605-206-3766 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be dilapidated or a bearing could need to be lubed. We are aware that maintenance often slips your mind, but our professionals can get your furnace running quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still hearing noise, Precision Mechanical can assist you. It’s essential to get loose ductwork taken care of fast, since it can make comfort issues in your residence and inflate your gas costs.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal sound typically means there’s an issue with your furnace’s blower. Turn off your furnace off immediately and call us at 605-206-3766 for support.
