When your furnace is operating correctly, it should deliver warmth without creating too much noise. While it’s expected to hear your furnace making noise as it starts up, other noises are signaling your furnace should get immediate professional help.

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 specialists are here to fix the problem with the best furnace repair in Muskogee, Oklahoma.

1. Furnace Makes Banging or Knocking Sounds

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

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over the years, so that’s why it’s critical to set seasonal furnace maintenance with Hix Air Conditioning Service, Inc.. One of the things our techs complete during this work is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can emit carbon monoxide, which is ordinarily emitted outside. This toxic gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Hix Air Conditioning Service, Inc. urges you to turn it off and reaching us at 918-682-8238. Significant natural gas in your furnace or a cracked heat exchanger are critical problems that necessitate fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver heated air throughout your house. If the ductwork wasn’t put in correctly or is aging, it can be noisy when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Contact Hix Air Conditioning Service, Inc. at 918-682-8238 and we’ll determine 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 issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or cooled air across your house, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be related to something little, like a loose screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating pros at 918-682-8238 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to get your attention it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubed. We realize that maintenance often slips your mind, but our techs can get your furnace operating quietly again quickly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also notice whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing noise, Hix Air Conditioning Service, Inc. can provide support. It’s critical to get loose ductwork repaired fast, because it can create comfort issues in your house and inflate your heating costs.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket typically means there’s an issue with your furnace’s blower. Switch off your furnace off promptly and call our pros at 918-682-8238 for support.
