When your furnace is operating like it should, it should provide warmth without generating too much sound. While it’s normal to notice your furnace making noise as it starts up, other sounds are indicating your furnace requires immediate professional assistance.
Here are some of the most common furnace noises and what they might be indicating. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Holdrege, Nebraska.
1. Furnace Makes Banging or Knocking Sounds
You may 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 may mean there could be a few problems. These include gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over time, so that’s why it’s important to book seasonal furnace maintenance with Durable Service. One of the tasks our pros complete during this work is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can discharge carbon monoxide, which is ordinarily emitted outdoors. This hazardous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Durable Service advises turning it off and contacting us at 308-995-8177. Significant natural gas in your furnace or a broken heat exchanger are critical troubles that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver hot air around your house. If the ductwork wasn’t installed properly or is aging, it can make a lot of noise when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Contact Durable Service at 308-995-8177 and we’ll determine the problem.
2. Furnace Buzzes Constantly
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often means there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the correct voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or chilly air across your space, and a capacitor, which starts 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 critical, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 308-995-8177 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 trying to tell you it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubricated. We are aware that maintenance often slips your mind, but our pros can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve checked your vents but are still noticing whistling, Durable Service can help. It’s critical to get loose ductwork taken care of fast, as it can result in comfort issues in your residence and drive up your energy bills.
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 frequently means there’s trouble with your furnace’s blower. Switch off your furnace off immediately and reach us at 308-995-8177 for help.
