When your furnace is running correctly, it should give heat without creating too much sound. While it’s common to catch your furnace making noise as it begins running, other disruptions are signaling your furnace requires immediate professional support.

Here are some of the most reported furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Michigan City, Indiana.

1. Furnace Makes Banging or Knocking Sounds

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

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over the years, so that’s why it’s critical to set routine furnace maintenance with Paniccia Heating & Cooling. One of the jobs our techs do during this appointment is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes more time. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can discharge carbon monoxide, which is normally emitted outside. This toxic gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Paniccia Heating & Cooling urges you to turn it off and contacting us at 219-872-2198. Too much natural gas in your furnace or a ruptured heat exchanger are hazardous issues that necessitate prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air around your house. If the ductwork wasn’t put in properly 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. Contact Paniccia Heating & Cooling at 219-872-2198 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t wait 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 relies on an internal transformer to operate on the right voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or cooled air across your space, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be the result of something minor, like a loose screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and calling our heating professionals at 219-872-2198 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to get your attention it requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing could need to be lubricated. We know that maintenance often slips your mind, but our technicians can get your furnace heating quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still sensing noise, Paniccia Heating & Cooling can provide support. It’s important to get loose ductwork fixed quickly, as it can create comfort troubles in your home and drive up your energy 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 racket typically means there’s a problem with your furnace’s blower. Turn off your furnace off now and contact us at 219-872-2198 for help.
