When your furnace is running like it should, it should give warmth without generating too much disruption. While it’s normal to hear your furnace making noise as it starts up, other noises are indicating your furnace should get immediate professional help.
Here are some of the most common furnace noises and what they can be signaling. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Chadron, NE.
1. Furnace Making a Banging Noise
You might 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 mean there could be a few problems. These range from gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy over time, so that’s why it’s critical to schedule seasonal furnace maintenance with MPC Heating & Cooling. One of the jobs our pros perform during this work is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes more time. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can emit carbon monoxide, which is regularly released outside. This hazardous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, MPC Heating & Cooling urges you to turn it off and calling us at 308-832-4321. Too much natural gas in your furnace or a fractured heat exchanger are hazardous issues that require prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air throughout your residence. If the ductwork wasn’t put in properly or is getting old, it can be loud when your furnace runs. This may 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 determine the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes warm or cooled air across your home, and a capacitor, which turns on 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 may be related to something little, like an unsecure screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating professionals at 308-832-4321 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to tell you it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be dilapidated or a bearing might need to be greased. We realize that maintenance frequently slips your mind, but our technicians 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 frequently due to an air leak in your ductwork. You may also hear whistling while the furnace is on if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing whistling, MPC Heating & Cooling can help. It’s important to get loose ductwork fixed without delay, since it can create comfort troubles in your home and increase your utility bills.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal sound typically means there’s a problem with your furnace’s blower. Switch off your furnace off now and reach us at 308-832-4321 for help.
