When your furnace is running properly, it should deliver warm air without generating too much noise. While it’s expected to notice your furnace making noise as it turns on, other disruptions are showing your furnace needs immediate professional assistance.
Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making a strange noise, our friendly heating pros are here to help with the best furnace repair in Chadron, Nebraska.
1. Furnace Makes Banging or Knocking Sounds
You may have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a couple of problems. These include gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s essential to set seasonal furnace maintenance with MPC Heating & Cooling. One of the tasks our pros 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 if ignition takes longer than normal. The following gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can emit carbon monoxide, which is regularly vented outdoors. This hazardous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, MPC Heating & Cooling advises turning it off and contacting us at 308-832-4321. Significant 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 uses ductwork to provide warm air across your house. If the ductwork wasn’t installed right or is getting dated, it can be loud when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Contact MPC Heating & Cooling at 308-832-4321 and we’ll figure out the problem.
2. Furnace Buzzes Constantly
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cooled air throughout your residence, and a capacitor, which turns on the motor. If either of these parts 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 can be the result of something little, like a loose screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and contacting our heating professionals at 308-832-4321 for assistance.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance often slips your mind, but our pros can get your furnace operating quietly again quickly.
5. Furnace Whistles
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 running if a floor vent isn’t secure. If you’ve examined your vents but are still sensing whistling, MPC Heating & Cooling can help. It’s essential to get loose ductwork taken care of quickly, because it can create comfort troubles in your residence and increase your utility costs.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket typically means there’s a problem with your furnace’s blower. Shut down your furnace off now and contact our professionals at 308-832-4321 for help.
