When your furnace is running correctly, it should provide warmth without making too much noise. While it’s normal to notice your furnace making noise as it starts up, other noises are showing your furnace needs immediate professional help.

Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making a weird noise, our friendly heating specialists are here to help with the best furnace repair in Port Clinton, Ohio.

1. Furnace Makes a Banging Sound

You could have an urgent situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be several problems. These involve gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty as time passes, so that’s why it’s critical to book yearly furnace maintenance with Ohler & Holzhauer Inc.. One of the tasks our techs perform during this service is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise when ignition takes more time. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can discharge carbon monoxide, which is ordinarily emitted 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, Ohler & Holzhauer Inc. advises turning it off and contacting us at 419-465-8722. Too much natural gas in your furnace or a ruptured heat exchanger are serious issues that necessitate fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide heated air across your house. If the ductwork wasn’t designed correctly or is getting old, it can be noisy when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Contact Ohler & Holzhauer Inc. at 419-465-8722 and we’ll pinpoint the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cold air across your space, and a capacitor, which starts the motor. If either of these components are failing, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be due to something small, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating specialists at 419-465-8722 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to alert you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubricated. We know that maintenance often slips your mind, but our techs can get your furnace running quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You could also be aware of whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing whistling, Ohler & Holzhauer Inc. can help. It’s essential to get loose ductwork repaired without delay, because it can create comfort problems in your residence and inflate your gas costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound frequently means there’s a problem with your furnace’s blower. Turn off your furnace off immediately and call our pros at 419-465-8722 for assistance.
