When your furnace is working like it should, it should deliver warm air without creating too much disruption. While it’s normal to notice your furnace making noise as it begins running, other noises are showing your furnace should get immediate professional assistance.

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

1. Furnace Makes Banging or Knocking Sounds

You might have a serious issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These range from gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy as time passes, so that’s why it’s critical to set seasonal furnace maintenance with Durable Service. One of the jobs our technicians complete during this appointment is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup can break your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can discharge carbon monoxide, which is regularly emitted outdoors. This hazardous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Durable Service urges you to turn it off and reaching us at 308-995-8177. Significant natural gas in your furnace or a cracked heat exchanger are critical issues that should get prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air throughout your home. If the ductwork wasn’t installed correctly or is aging, it can make a lot of noise when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Contact Durable Service at 308-995-8177 and we’ll determine the problem.

2. Furnace Buzzes Constantly

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

Your furnace depends on an internal transformer to work on the correct 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 hot or cold air throughout your home, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be the result of something little, like an unfastened screw, or something critical, like a broken component. In either case, we urge you to shut your furnace off and calling our heating professionals at 308-995-8177 for assistance.

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 attempting to get your attention it needs 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 lubed. We realize that maintenance sometimes slips your mind, but our pros can get your furnace running quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You could also hear whistling while the furnace is working if a floor vent is loose. If you’ve examined your vents but are still noticing noise, Durable Service can assist you. It’s critical to get loose ductwork repaired without delay, because it can make comfort problems in your residence and inflate your heating costs.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Shut down your furnace off immediately and call our pros at 308-995-8177 for help.
