When your furnace is operating correctly, it should deliver heat without generating too much disruption. While it’s normal to hear your furnace making noise as it begins running, other noises are showing your furnace requires immediate professional help.

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

1. Furnace Making a Banging Noise

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

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s essential to set annual furnace maintenance with Edington Heating & Cooling Inc. One of the tasks our technicians complete during this service is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The following gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can leak carbon monoxide, which is regularly vented away from your home. This dangerous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Edington Heating & Cooling Inc advises turning it off and calling us at 937-558-9478. Significant natural gas in your furnace or a cracked heat exchanger are critical issues that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move heated air throughout your residence. If the ductwork wasn’t put in right or is getting dated, it can be loud when your furnace is on. This may be the issue if your furnace makes a banging noise when it shuts off. Contact Edington Heating & Cooling Inc at 937-558-9478 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

If you observe 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 uses an internal transformer to work on the correct voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or chilly air around your house, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be the result of something little, like a loose screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and calling our heating professionals at 937-558-9478 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to tell you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be greased. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again fast.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still hearing whistling, Edington Heating & Cooling Inc can assist you. It’s essential to get loose ductwork fixed without delay, because it can create comfort issues in your home and drive up your heating costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket often means there’s trouble with your furnace’s blower. Switch off your furnace off promptly and call us at 937-558-9478 for help.
