When your furnace is running like it should, it should give warmth without generating too much sound. While it’s expected to hear your furnace making noise as it turns on, other disruptions are indicating your furnace needs immediate professional assistance.
Here are some of the most common furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating pros are here to help with the best furnace repair in Middletown, Delaware.
1. Furnace Making a Banging Noise
You might have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a few problems. These include gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy over the years, so that’s why it’s essential to set seasonal furnace maintenance with SchagrinGAS Company. One of the tasks our pros complete during this service is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can discharge carbon monoxide, which is regularly released away from your home. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, SchagrinGAS Company recommends turning it off and reaching us at 302-231-1380. Too much natural gas in your furnace or a fractured heat exchanger are critical troubles that should get immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air across your residence. If the ductwork wasn’t designed properly or is getting dated, it can make a lot of noise when your furnace is on. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with SchagrinGAS Company at 302-231-1380 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you observe 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 needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cooled air around your house, 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 can be related to something small, like a loose screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating pros at 302-231-1380 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to tell you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing might need to be greased. We realize that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still hearing sound, SchagrinGAS Company can provide support. It’s critical to get loose ductwork fixed quickly, because it can create comfort issues in your home and inflate your energy bills.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Shut down your furnace off promptly and call our professionals at 302-231-1380 for help.
