When your furnace is working correctly, it should give warmth without making too much noise. While it’s normal to catch your furnace making noise as it starts up, other disruptions are showing your furnace needs immediate professional help.

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

1. Furnace Making a Banging Noise

You could have a serious issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These include gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s essential to schedule yearly furnace maintenance with Comfort Concepts Heating & Air Conditioning. One of the jobs our techs do during this work is clean your furnace’s burners. When this piece gets grimy, you may hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can leak carbon monoxide, which is ordinarily vented away from your home. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Comfort Concepts Heating & Air Conditioning recommends turning it off and calling us at 405-494-7444. Significant natural gas in your furnace or a ruptured heat exchanger are critical troubles that should get prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move hot air across your home. If the ductwork wasn’t designed right or is getting old, it can be noisy when your furnace runs. This may be the issue if your furnace makes a banging noise when it shuts off. Call Comfort Concepts Heating & Air Conditioning at 405-494-7444 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t delay calling 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 is loose, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cold air around your rooms, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be due to something small, like a loose screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating specialists at 405-494-7444 for help.

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 alert you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubed. We realize that maintenance frequently slips your mind, but our technicians can get your furnace operating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still sensing noise, Comfort Concepts Heating & Air Conditioning can help. It’s essential to get loose ductwork fixed quickly, because it can create comfort issues in your house and inflate your energy bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound frequently means there’s an issue with your furnace’s blower. Turn off your furnace off right away and reach our pros at 405-494-7444 for help.
