When your furnace is working like it should, it should give heat without generating too much sound. While it’s common to notice your furnace making noise as it begins running, other noises are indicating your furnace needs immediate professional support.

Here are some of the most common furnace noises and what they could mean. If your furnace is making a weird noise, our friendly heating professionals are here to help with the best furnace repair in Troy, Ohio.

1. Furnace Making a Banging Noise

You may have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These involve gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy as time passes, so that’s why it’s essential to book routine furnace maintenance with Edington Heating & Cooling Inc. One of the jobs our technicians perform during this service is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise after ignition is delayed. The following gas buildup might crack your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can discharge carbon monoxide, which is regularly vented outdoors. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Edington Heating & Cooling Inc advises turning it off and contacting us at 937-558-9478. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous troubles that should get prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide warm air around your home. If the ductwork wasn’t put in properly or is aging, it can make a lot of noise when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Edington Heating & Cooling Inc at 937-558-9478 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually means there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to work on the correct voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or cold air around your residence, and a capacitor, which turns on the motor. If either of these pieces are fading, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be related to something minor, like an unsecure screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating professionals at 937-558-9478 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 requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubed. We are aware 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 detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You may also notice whistling while the furnace is operating if a floor vent is loose. If you’ve checked your vents but are still sensing whistling, Edington Heating & Cooling Inc can provide support. It’s critical to get loose ductwork repaired quickly, as it can make comfort problems in your residence and increase your heating costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise often means there’s a problem with your furnace’s blower. Switch off your furnace off now and reach our pros at 937-558-9478 for help.
