When your furnace is operating correctly, it should provide heat without making too much disruption. While it’s normal to catch your furnace making noise as it turns on, other noises are indicating your furnace needs immediate professional assistance.
Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Alliance, Nebraska.
1. Furnace Making a Banging Noise
You may have a critical situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These involve gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty as time passes, so that’s why it’s critical to schedule annual furnace maintenance with Jack's Heating, Cooling, Stoves & Fireplaces. One of the things our technicians complete during this service is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can emit carbon monoxide, which is normally vented outdoors. This hazardous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Jack's Heating, Cooling, Stoves & Fireplaces urges you to turn it off and contacting us at 308-321-4703. Excessive natural gas in your furnace or a cracked heat exchanger are dangerous issues that require immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air around your residence. If the ductwork wasn’t designed correctly or is getting old, it can be noisy when your furnace runs. This could be the case if your furnace makes a banging noise when it shuts off. Contact Jack's Heating, Cooling, Stoves & Fireplaces at 308-321-4703 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cooled air throughout your home, and a capacitor, which starts the motor. If either of these parts are going out, 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 due to something minor, like an unfastened screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 308-321-4703 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 get your attention it requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing may need to be greased. We are aware that maintenance often slips your mind, but our pros can get your furnace heating quietly again rapidly.
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 secure. If you’ve checked your vents but are still hearing sound, Jack's Heating, Cooling, Stoves & Fireplaces can help. It’s important to get loose ductwork repaired without delay, as it can make comfort troubles in your home and drive up your gas bills.
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 sound frequently means there’s a problem with your furnace’s blower. Switch off your furnace off right away and reach us at 308-321-4703 for support.
