1. Furnace Making a Banging Noise
You might have an urgent issue 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 a few problems. These include gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over time, so that’s why it’s critical to schedule annual furnace maintenance with Siloam Springs Heating & AC. One of the tasks our pros complete during this work is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can discharge carbon monoxide, which is regularly 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, Siloam Springs Heating & AC urges you to turn it off and contacting us at 479-308-8176. Too much 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 move heated air around your home. If the ductwork wasn’t installed properly or is getting old, it can be loud when your furnace is on. This might be the problem if your furnace makes a banging noise when it shuts off. Call Siloam Springs Heating & AC at 479-308-8176 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 usually is telling you there’s an electrical problem, 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 needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cooled air around your rooms, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something minor, like an unsecure screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating pros at 479-308-8176 for help.

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to get your attention it needs 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 lubricated. We are aware that maintenance often slips your mind, but our technicians can get your furnace running quietly again quickly.
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 be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve checked your vents but are still sensing noise, Siloam Springs Heating & AC can assist you. It’s critical to get loose ductwork repaired quickly, since it can create comfort troubles in your residence and inflate your utility expenses.
