When your furnace is running properly, it should provide heat without generating too much disruption. While it’s expected to notice your furnace making noise as it turns on, other disruptions are indicating your furnace needs immediate professional support.

Here are some of the most frequent furnace noises and what they might mean. If your furnace is making an atypical noise, our friendly heating specialists are here to assist with the best furnace repair in Muskogee, Oklahoma.

1. Furnace Makes a Banging Sound

You could have an urgent issue on your hands if you’re hearing 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 range from gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s essential to set annual furnace maintenance with Hix Air Conditioning Service, Inc.. One of the jobs our technicians perform during this work is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can discharge carbon monoxide, which is ordinarily vented away from your home. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Hix Air Conditioning Service, Inc. urges you to turn it off and contacting us at 918-682-8238. Too much natural gas in your furnace or a cracked heat exchanger are critical problems that necessitate prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver heated air around your residence. If the ductwork wasn’t installed correctly or is getting old, it can make a lot of noise when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Call Hix Air Conditioning Service, Inc. at 918-682-8238 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cooled air across your house, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be due to something small, like a loose screw, or something major, like a broken component. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 918-682-8238 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to tell you it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubricated. We know that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also hear whistling while the furnace is on if a floor vent isn’t tight. If you’ve examined your vents but are still sensing noise, Hix Air Conditioning Service, Inc. can help. It’s essential to get loose ductwork taken care of quickly, since it can result in comfort issues in your home and drive up your energy expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound usually means there’s an issue with your furnace’s blower. Shut down your furnace off right away and contact us at 918-682-8238 for assistance.
