1. Furnace Makes a Banging Sound

You may have a critical problem 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 several problems. These involve gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over the years, so that’s why it’s critical to set seasonal furnace maintenance with Ohler & Holzhauer Inc.. One of the jobs our professionals complete during this work is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise when ignition takes more time. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can discharge carbon monoxide, which is regularly emitted outdoors. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Ohler & Holzhauer Inc. urges you to turn it off and contacting us at 419-465-8722. Too much natural gas in your furnace or a fractured heat exchanger are dangerous problems that necessitate fast service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move warm air around your home. If the ductwork wasn’t designed properly or is getting dated, it can make a lot of noise when your furnace is on. This might be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Ohler & Holzhauer Inc. at 419-465-8722 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace depends on an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or cold air around your house, and a capacitor, which triggers the motor. If either of these parts are going out, 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 could be the result of something little, like a loose screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 419-465-8722 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to get your attention it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubed. We realize that maintenance often slips your mind, but our technicians can get your furnace heating quietly again fast.

5. Furnace Whistles

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 hear whistling while the furnace is on if a floor vent isn’t tight. If you’ve examined your vents but are still hearing sound, Ohler & Holzhauer Inc. can provide support. It’s important to get loose ductwork fixed quickly, since it can result in comfort issues in your residence and inflate your gas costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and call our professionals at 419-465-8722 for support.
