When your furnace is running properly, it should deliver warmth without generating too much noise. While it’s common to notice your furnace making noise as it begins running, other sounds are signaling your furnace requires immediate professional assistance.
Here are some of the most common furnace noises and what they can be indicating. If your furnace is making an odd noise, our friendly heating pros are here to help with the best furnace repair in Streamwood, Illinois.
1. Furnace Makes Banging or Knocking Sounds
You might have a serious problem 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 several problems. These include 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 essential to set seasonal furnace maintenance with Pure Comfort Heating and Air Conditioning. One of the things our pros perform during this work is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise when ignition takes more time. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can discharge carbon monoxide, which is regularly emitted away from your home. This dangerous gas can be fatal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Pure Comfort Heating and Air Conditioning advises turning it off and contacting us at 630-313-2509. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous problems that require immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver heated air around your residence. If the ductwork wasn’t put in properly or is aging, 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 Pure Comfort Heating and Air Conditioning at 630-313-2509 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or cooled air around your space, and a capacitor, which turns on the motor. If either of these pieces are fading, they will buzz when the furnace turns 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 unsecure screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 630-313-2509 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to tell you it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing might need to be lubricated. We know that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again rapidly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re hearing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still sensing sound, Pure Comfort Heating and Air Conditioning can assist you. It’s critical to get loose ductwork fixed fast, because it can make comfort issues in your residence and inflate your energy bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Switch off your furnace off promptly and contact our professionals at 630-313-2509 for support.
