When your furnace is working correctly, it should deliver heat without making too much sound. While it’s normal to hear your furnace making noise as it starts up, other disruptions are showing your furnace requires immediate professional support.
Here are some of the most reported furnace noises and what they can be indicating. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Holdrege, Nebraska.
1. Furnace Making a Banging Noise
You could have a serious issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be several problems. These involve gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty over time, so that’s why it’s important to set yearly furnace maintenance with Durable Service. One of the tasks our professionals perform during this service is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes more time. The subsequent gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can leak carbon monoxide, which is regularly released away from your home. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Durable Service advises turning it off and contacting us at 308-995-8177. Excessive natural gas in your furnace or a cracked heat exchanger are serious issues that necessitate fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver heated air throughout your residence. If the ductwork wasn’t installed right or is getting old, it can be noisy when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Durable Service at 308-995-8177 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the proper voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cold air around your home, and a capacitor, which triggers the motor. If either of these components are failing, 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 small, 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 pros at 308-995-8177 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to alert you it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing might need to be lubricated. We know that maintenance often slips your mind, but our pros can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may 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 noise, Durable Service can help. It’s critical to get loose ductwork repaired fast, because it can make comfort troubles in your home and drive up your utility costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s trouble with your furnace’s blower. Shut down your furnace off promptly and contact us at 308-995-8177 for assistance.
