When your furnace is running like it should, it should provide heat without generating too much sound. While it’s normal to catch your furnace making noise as it turns on, other noises are showing your furnace should get immediate professional assistance.

Here are some of the most common furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Troy, Ohio.

1. Furnace Making a Banging Noise

You might have an urgent issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a few problems. These range from gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy as time passes, so that’s why it’s important to set annual furnace maintenance with Edington Heating & Cooling Inc. One of the jobs our pros perform 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 is delayed. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can emit carbon monoxide, which is normally vented outdoors. This toxic gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Edington Heating & Cooling Inc urges you to turn it off and calling us at 937-558-9478. Significant natural gas in your furnace or a fractured heat exchanger are dangerous problems that should get immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide heated air across your residence. If the ductwork wasn’t installed properly or is aging, it can be noisy when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Call Edington Heating & Cooling Inc at 937-558-9478 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or cold air around your space, and a capacitor, which starts the motor. If either of these components 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 related to something little, like a loose screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 937-558-9478 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubed. We know that maintenance frequently slips your mind, but our techs can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still sensing noise, Edington Heating & Cooling Inc can help. It’s essential to get loose ductwork repaired without delay, since it can make comfort troubles in your house and drive up your heating 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 racket usually means there’s trouble with your furnace’s blower. Shut down your furnace off right away and contact us at 937-558-9478 for help.
