Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Safford, Arizona.
1. Furnace Making a Banging Noise
You might have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a few problems. These involve gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over the years, so that’s why it’s critical to schedule yearly furnace maintenance with B&D Air Conditioning. One of the things our techs 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 longer than normal. The resulting gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can emit carbon monoxide, which is normally vented outdoors. This toxic gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, B&D Air Conditioning urges you to turn it off and contacting us at 928-432-6018. Significant natural gas in your furnace or a ruptured heat exchanger are critical issues that necessitate prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move heated air around your house. If the ductwork wasn’t installed properly or is getting old, it can be noisy when your furnace is heating. This could be the case if your furnace makes a banging noise when it shuts off. Contact B&D Air Conditioning at 928-432-6018 and we’ll pinpoint 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 frequently is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the proper voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or chilly air across your home, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something minor, like an unfastened screw, or something major, like a broken component. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 928-432-6018 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 alert you it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubed. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also hear whistling while the furnace is on if a floor vent is loose. If you’ve checked your vents but are still sensing noise, B&D Air Conditioning can provide support. It’s essential to get loose ductwork repaired quickly, as it can create comfort troubles in your house and increase your utility expenses.
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 racket frequently means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and call our professionals at 928-432-6018 for help.
