When your furnace is running properly, it should deliver warm air without generating too much sound. While it’s normal to notice your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional help.

Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making an odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Port Clinton, Ohio.

1. Furnace Making a Banging Noise

You might have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over the years, so that’s why it’s essential to book yearly furnace maintenance with Ohler & Holzhauer Inc.. One of the jobs our professionals do during this work is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can discharge carbon monoxide, which is ordinarily released outside. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Ohler & Holzhauer Inc. recommends turning it off and reaching us at 419-465-8722. Too much natural gas in your furnace or a ruptured heat exchanger are serious troubles that should get fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver heated air throughout your house. If the ductwork wasn’t installed properly or is getting dated, it can be noisy when your furnace is on. This may be the issue if your furnace makes a banging noise when it shuts off. Call Ohler & Holzhauer Inc. at 419-465-8722 and we’ll figure out 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 typically means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or cooled air throughout your home, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be related to something minor, like an unsecure screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and calling our heating professionals 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 going, it’s trying to alert you it could use some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubricated. We are aware that maintenance often slips your mind, but our techs can get your furnace running quietly again rapidly.

5. Furnace Whistles

When you’re noticing 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 working if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing noise, Ohler & Holzhauer Inc. can help. It’s important to get loose ductwork taken care of quickly, because it can make comfort issues in your house and increase your heating expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Turn off your furnace off promptly and contact our pros at 419-465-8722 for support.
