When your furnace is running correctly, it should give warm air without creating too much sound. While it’s normal to hear your furnace making noise as it starts up, other noises are signaling your furnace should get immediate professional assistance.

Here are some of the most common furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Holdrege, Nebraska.

1. Furnace Makes a Banging Sound

You may have a serious situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a couple of problems. These include gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s important to schedule routine furnace maintenance with Durable Service. One of the things our pros do during this service is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise when ignition takes more time. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can leak carbon monoxide, which is regularly emitted outside. This toxic gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Durable Service urges you to turn it off and calling us at 308-995-8177. Significant natural gas in your furnace or a broken heat exchanger are critical troubles that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move warm air across your residence. If the ductwork wasn’t designed properly or is aging, it can be loud when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Call Durable Service at 308-995-8177 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace relies on 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 has a blower motor, which distributes hot or cold air throughout your space, and a capacitor, which starts the motor. If either of these components are failing, 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 due to something small, like an unfastened screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 308-995-8177 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to tell you it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be greased. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again quickly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still noticing sound, Durable Service can provide support. It’s important to get loose ductwork fixed quickly, since it can result in comfort problems in your residence and inflate your heating costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

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

When you’re noticing a weird noise from your furnace, Durable Service is ready to help. Contact us at 308-995-8177 to schedule your furnace repair appointment right away.
