When your furnace is working correctly, it should give warm air without creating too much noise. While it’s expected to hear your furnace making noise as it begins running, other disruptions are indicating your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to help with the best furnace repair in Holdrege, Nebraska.

1. Furnace Making a Banging Noise

You could have a critical issue on your hands if you’re hearing 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 include gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over time, so that’s why it’s essential to book yearly furnace maintenance with Durable Service. One of the tasks our techs perform during this appointment is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise after ignition is delayed. The subsequent gas buildup may crack your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can leak carbon monoxide, which is ordinarily emitted outside. This dangerous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Durable Service urges you to turn it off and reaching us at 308-995-8177. Too much natural gas in your furnace or a fractured heat exchanger are dangerous issues that require prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide warm air throughout your house. If the ductwork wasn’t designed properly or is getting old, it can make a lot of noise when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Durable Service at 308-995-8177 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you might 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 home, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be the result of something minor, like an unsecure screw, or something critical, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 308-995-8177 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubricated. We know that maintenance often slips your mind, but our techs can get your furnace heating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You may also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing sound, Durable Service can provide support. It’s critical to get loose ductwork repaired fast, because it can make comfort problems in your home and drive up your utility expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal racket often means there’s an issue with your furnace’s blower. Turn off your furnace off now and call our professionals at 308-995-8177 for help.
