Here are some of the most common furnace noises and what they could be signaling. If your furnace is making an odd noise, our friendly heating pros are here to help with the best furnace repair in Carson City, Nevada.
1. Furnace Makes Banging or Knocking Sounds
You might have an urgent situation 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 couple of problems. These involve gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy as time passes, so that’s why it’s critical to book annual furnace maintenance with Anderson Heating & A/C. One of the things our techs perform during this work is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The following gas buildup might break your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can leak carbon monoxide, which is normally vented outdoors. This toxic gas can be deadly 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 775-854-9700. Too much natural gas in your furnace or a ruptured heat exchanger are dangerous issues that necessitate fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver hot air across your house. If the ductwork wasn’t put in right or is getting old, it can be noisy when your furnace is on. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Anderson Heating & A/C at 775-854-9700 and we’ll determine 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 usually is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the right voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or cold air around your residence, and a capacitor, which turns on the motor. If either of these parts are going out, they will buzz when the furnace starts.
3. Furnace Rattles
If your furnace is making a rattling noise, it could be due to something small, like an unfastened screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating pros at 775-854-9700 for assistance.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it requires some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing may need to be greased. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace heating quietly again fast.
5. Furnace Whistles
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 operating if a floor vent isn’t tight. If you’ve checked your vents but are still hearing whistling, Anderson Heating & A/C can help. It’s critical to get loose ductwork fixed quickly, since it can result in comfort issues in your home and inflate your energy bills.
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 typically means there’s an issue with your furnace’s blower. Turn off your furnace off promptly and contact our pros at 775-854-9700 for help.
