When your furnace is working like it should, it should deliver heat without making too much disruption. While it’s common to hear your furnace making noise as it begins running, other sounds are indicating your furnace requires immediate professional assistance.

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

1. Furnace Making a Banging Noise

You may have a critical problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a few problems. These include gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over the years, so that’s why it’s critical to set yearly furnace maintenance with Comfort Concepts Heating & Air Conditioning. One of the jobs our technicians complete during this work is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup may break your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can leak carbon monoxide, which is ordinarily vented outside. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Comfort Concepts Heating & Air Conditioning advises turning it off and reaching us at 405-494-7444. Significant natural gas in your furnace or a broken heat exchanger are critical problems that should get immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air throughout your residence. If the ductwork wasn’t designed properly or is getting dated, it can be noisy when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Call Comfort Concepts Heating & Air Conditioning at 405-494-7444 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to operate on the proper voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cooled air around your house, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something minor, like a loose screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating pros at 405-494-7444 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubed. We know that maintenance often slips your mind, but our techs can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent is loose. If you’ve examined your vents but are still sensing sound, Comfort Concepts Heating & Air Conditioning can assist you. It’s essential to get loose ductwork repaired quickly, because it can make comfort troubles in your residence and drive up your gas bills.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound typically means there’s an issue with your furnace’s blower. Shut down your furnace off now and reach us at 405-494-7444 for help.
