When your furnace is working properly, it should deliver warmth without making too much noise. While it’s common to hear your furnace making noise as it turns on, other disruptions are indicating your furnace should get immediate professional help.

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

1. Furnace Makes a Banging Sound

You might have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These range from gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over time, so that’s why it’s important to book routine furnace maintenance with Just Right Heating and Cooling. One of the things our pros complete during this work is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can leak carbon monoxide, which is ordinarily vented away from your home. This toxic gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Just Right Heating and Cooling advises turning it off and contacting us at 513-392-4969. Significant natural gas in your furnace or a ruptured heat exchanger are critical troubles that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move heated air across your home. If the ductwork wasn’t put in right or is getting old, it can make a lot of noise when your furnace is on. This could be the issue 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 delay calling us. A buzzing sound often 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 throughout your residence, and a capacitor, which starts the motor. If either of these components are going out, 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 could be the result of something minor, like an unfastened screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating pros at 513-392-4969 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to alert you it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing could need to be lubricated. We know that maintenance often slips your mind, but our professionals can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still sensing sound, Just Right Heating and Cooling can provide support. It’s critical to get loose ductwork taken care of quickly, as it can make comfort problems in your home and increase your gas bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound usually means there’s trouble with your furnace’s blower. Turn off your furnace off promptly and call us at 513-392-4969 for help.
