When your furnace is operating like it should, it should give warm air without creating too much noise. While it’s common to hear your furnace making noise as it begins running, other sounds are showing your furnace needs immediate professional support.

Here are some of the most common furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in Omaha, Nebraska.

1. Furnace Making a Banging Noise

You could have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a couple of problems. These range from gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy as time passes, so that’s why it’s critical to book yearly furnace maintenance with The Frazier Company. One of the jobs our technicians do during this service is clean your furnace’s burners. When this part gets grubby, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can leak carbon monoxide, which is normally emitted away from your home. This toxic gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, The Frazier Company advises turning it off and contacting us at 402-628-0206. Excessive natural gas in your furnace or a cracked heat exchanger are serious issues that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move hot air throughout your home. If the ductwork wasn’t designed correctly or is getting dated, it can be noisy when your furnace is heating. This may be the issue if your furnace makes a banging noise when it shuts off. Get in touch with The Frazier Company at 402-628-0206 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently 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 notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or chilly air throughout your rooms, and a capacitor, which turns on the motor. If either of these components are failing, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be related to something minor, like a loose screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 402-628-0206 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to tell you it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our professionals 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 frequently due to an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing noise, The Frazier Company can provide support. It’s important to get loose ductwork repaired quickly, as it can create comfort problems in your home and increase your gas bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal noise often means there’s a problem with your furnace’s blower. Shut down your furnace off promptly and contact our pros at 402-628-0206 for assistance.
