When your furnace is operating properly, it should provide warm air without making too much noise. While it’s expected to hear your furnace making noise as it turns on, other noises are indicating your furnace requires immediate professional assistance.

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

1. Furnace Makes a Banging Sound

You might have an urgent situation 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 several problems. These include gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s critical to schedule routine furnace maintenance with Stanford Heating & Cooling. One of the jobs our professionals do during this service is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can discharge carbon monoxide, which is ordinarily released outdoors. This hazardous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Stanford Heating & Cooling urges you to turn it off and contacting us at 812-825-8695. Too much natural gas in your furnace or a broken heat exchanger are serious issues that should get fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move heated air around your house. If the ductwork wasn’t put in correctly or is getting dated, it can be noisy when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Stanford Heating & Cooling at 812-825-8695 and we’ll figure out 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 usually is telling you 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 needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or chilly air throughout your home, and a capacitor, which starts the motor. If either of these parts are going out, 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 due to something minor, like a loose screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and calling our heating professionals at 812-825-8695 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubed. We realize that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still noticing whistling, Stanford Heating & Cooling can assist you. It’s essential to get loose ductwork fixed fast, since it can create comfort problems in your home and inflate your gas expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket frequently means there’s trouble with your furnace’s blower. Switch off your furnace off right away and contact our professionals at 812-825-8695 for assistance.
