When your furnace is operating like it should, it should deliver warm air without creating too much sound. While it’s expected to catch your furnace making noise as it starts up, other sounds are indicating your furnace should get immediate professional assistance.

Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in Goshen, Ohio.

1. Furnace Making a Banging Noise

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

Banging Sounds Coming from Your Furnace

Your heating system turns grimy as time passes, so that’s why it’s important to schedule routine furnace maintenance with Just Right Heating and Cooling. One of the tasks our techs do during this work is clean your furnace’s burners. When this part gets grubby, you might hear your furnace making a loud rumbling noise if ignition is delayed. The subsequent gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can emit carbon monoxide, which is normally emitted outdoors. This hazardous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Just Right Heating and Cooling advises turning it off and reaching us at 513-392-4969. Excessive natural gas in your furnace or a cracked heat exchanger are dangerous problems that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move warm air across your home. If the ductwork wasn’t designed right or is aging, it can be loud when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Call Just Right Heating and Cooling at 513-392-4969 and we’ll pinpoint the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace uses an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or chilly air across your house, and a capacitor, which starts the motor. If either of these parts are failing, 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 can be the result of something small, like an unfastened screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating professionals at 513-392-4969 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 alert you it requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing may need to be lubed. We are aware that maintenance often slips your mind, but our pros 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 hear whistling while the furnace is on if a floor vent is loose. If you’ve examined your vents but are still hearing whistling, Just Right Heating and Cooling can provide support. It’s critical to get loose ductwork repaired without delay, because it can make comfort troubles in your home and increase your heating bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and reach us at 513-392-4969 for support.
