When your furnace is working correctly, it should provide warm air without creating too much noise. While it’s normal to catch your furnace making noise as it begins running, other sounds are showing your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making a strange noise, our friendly heating pros are here to fix the problem with the best furnace repair in Chadron, Nebraska.

1. Furnace Making a Banging Noise

You might have an urgent problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These involve gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy as time passes, so that’s why it’s important to schedule yearly furnace maintenance with MPC Heating & Cooling. One of the jobs our professionals perform during this appointment is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The following gas buildup might break your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can leak carbon monoxide, which is normally released away from your home. This dangerous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, MPC Heating & Cooling advises turning it off and reaching us at 308-832-4321. Significant natural gas in your furnace or a broken heat exchanger are critical problems that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air around your home. If the ductwork wasn’t installed right or is aging, it can be noisy when your furnace runs. This might be the issue 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 Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to operate on the proper voltage. If wires or the box is loose, you may hear 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 rooms, and a capacitor, which starts the motor. If either of these components 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 could be due to something little, like an unfastened screw, or something major, like a broken part. In either case, we advise shutting your furnace off and calling our heating specialists 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 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 worn down or a bearing might need to be lubricated. We realize that maintenance often slips your mind, but our professionals 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 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 looked at your vents but are still hearing noise, MPC Heating & Cooling can help. It’s important to get loose ductwork repaired fast, since it can make comfort troubles in your home and drive up your heating 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 noise frequently means there’s a problem with your furnace’s blower. Switch off your furnace off promptly and reach our pros at 308-832-4321 for help.
