When your furnace is working correctly, it should provide heat without making too much sound. While it’s normal to catch your furnace making noise as it turns on, other noises are showing your furnace needs immediate professional help.

Here are some of the most reported furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating specialists are here to help with the best furnace repair in Chadron, Nebraska.

1. Furnace Making a Banging Noise

You may have a critical problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a couple of problems. These range from gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over time, so that’s why it’s essential to book annual furnace maintenance with MPC Heating & Cooling. One of the things our technicians complete during this service is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can emit carbon monoxide, which is regularly released away from your home. This hazardous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, MPC Heating & Cooling urges you to turn it off and calling us at 308-832-4321. Excessive natural gas in your furnace or a broken heat exchanger are critical troubles that necessitate fast service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air throughout your home. If the ductwork wasn’t designed correctly or is getting old, it can be loud when your furnace is heating. This might be the issue 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 figure out the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cold air around your home, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be related to something minor, like a loose screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and calling our heating professionals at 308-832-4321 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to alert you it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be lubricated. We know that maintenance often slips your mind, but our technicians can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also be aware of whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still hearing sound, MPC Heating & Cooling can help. It’s critical to get loose ductwork repaired fast, because it can result in comfort troubles in your residence and increase your energy 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 often means there’s an issue with your furnace’s blower. Shut down your furnace off right away and call our professionals at 308-832-4321 for assistance.
