When your furnace is working properly, it should provide warmth without creating too much disruption. While it’s normal to notice your furnace making noise as it turns on, other noises are signaling your furnace needs immediate professional help.
Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Port Clinton, Ohio.
1. Furnace Making a Banging Noise
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 include gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s critical to book routine furnace maintenance with Ohler & Holzhauer Inc.. One of the things our techs complete during this appointment is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can leak carbon monoxide, which is ordinarily released outdoors. This toxic gas can be deadly in large concentrations.
If you’re noticing 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 fractured heat exchanger are critical problems that should get immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move warm air around your house. If the ductwork wasn’t installed correctly or is getting old, it can make a lot of noise when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Call Ohler & Holzhauer Inc. at 419-465-8722 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the correct voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cooled air across your space, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace starts.
3. Furnace Rattles
If your furnace is making a rattling noise, it can be due to something little, like an unsecure screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and contacting our heating professionals at 419-465-8722 for assistance.
4. Furnace Making a Squealing Noise
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 neglected furnace maintenance recently, belts could be worn out or a bearing could need to be lubed. We know that maintenance sometimes slips your mind, but our techs 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 typically due to an air leak in your ductwork. You might also notice whistling while the furnace is on if a floor vent is loose. If you’ve looked at your vents but are still sensing whistling, Ohler & Holzhauer Inc. can help. It’s critical to get loose ductwork taken care of quickly, as it can result in comfort troubles in your home and increase your utility expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound usually means there’s a problem with your furnace’s blower. Switch off your furnace off right away and reach our professionals at 419-465-8722 for assistance.
