When your furnace is running properly, it should deliver warmth without generating too much noise. While it’s expected to notice your furnace making noise as it starts up, other sounds are signaling your furnace needs immediate professional assistance.

Here are some of the most reported furnace noises and what they can be signaling. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Michigan City, Indiana.

1. Furnace Making a Banging Noise

You could have a serious 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 a couple of problems. These range from gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over time, so that’s why it’s critical to set routine furnace maintenance with Paniccia Heating & Cooling. One of the things our techs do during this appointment is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can leak carbon monoxide, which is normally released outdoors. 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 advises turning it off and contacting us at 219-872-2198. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous problems that should get fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air across your residence. If the ductwork wasn’t designed correctly or is getting old, it can be loud when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Paniccia Heating & Cooling at 219-872-2198 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace relies on an internal transformer to work on the proper voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cooled air throughout your house, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be due to something small, like a loose screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating pros at 219-872-2198 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We are aware that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing 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 operating if a floor vent is loose. If you’ve examined your vents but are still sensing sound, Paniccia Heating & Cooling can provide support. It’s critical to get loose ductwork taken care of without delay, because it can create comfort problems in your residence and drive up your utility expenses.

6. Furnace Making a Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s an issue with your furnace’s blower. Turn off your furnace off immediately and contact us at 219-872-2198 for support.
