When your furnace is operating like it should, it should give warmth without making too much sound. While it’s normal to catch your furnace making noise as it begins running, other sounds are signaling your furnace requires immediate professional help.
Here are some of the most reported furnace noises and what they could mean. If your furnace is making a weird noise, our friendly heating specialists are here to assist with the best furnace repair in Chadron, Nebraska.
1. Furnace Makes Banging or Knocking Sounds
You could have a critical issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These involve gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy over time, so that’s why it’s important to set seasonal furnace maintenance with MPC Heating & Cooling. One of the jobs our technicians complete during this appointment is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can emit carbon monoxide, which is ordinarily emitted outdoors. This hazardous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, MPC Heating & Cooling recommends turning it off and calling us at 308-832-4321. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous troubles that require prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move heated air throughout your house. If the ductwork wasn’t designed properly or is getting dated, it can be loud when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Get in touch with MPC Heating & Cooling at 308-832-4321 and we’ll pinpoint the problem.
2. Furnace Makes a Buzzing Sound
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes heated or chilly air around your space, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace turns on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it may be related to something minor, like an unsecure screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating pros at 308-832-4321 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it could use some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be greased. We know that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again rapidly.
5. Furnace Whistles
When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You could also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still hearing whistling, MPC Heating & Cooling can assist you. It’s critical to get loose ductwork repaired without delay, because it can create comfort problems in your home and drive up your energy expenses.
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 noise typically means there’s trouble with your furnace’s blower. Shut down your furnace off now and contact us at 308-832-4321 for support.
