When your furnace is running correctly, it should deliver warm air without generating too much sound. While it’s common to catch your furnace making noise as it begins running, other disruptions are signaling your furnace should get immediate professional assistance.

Here are some of the most frequent furnace noises and what they can mean. 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 Makes Banging or Knocking Sounds

You might have a serious issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These involve gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy as time passes, so that’s why it’s essential to set annual furnace maintenance with Paniccia Heating & Cooling. One of the things our techs do during this work is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup might crack your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can discharge carbon monoxide, which is regularly vented outside. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Paniccia Heating & Cooling advises turning it off and contacting us at 219-872-2198. Too much natural gas in your furnace or a cracked heat exchanger are critical problems that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver warm air throughout your house. If the ductwork wasn’t installed properly or is getting old, it can be loud when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Contact Paniccia Heating & Cooling at 219-872-2198 and we’ll pinpoint the problem.

2. Furnace Makes a Buzzing Sound

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or cold air around your home, and a capacitor, which starts the motor. If either of these components 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 little, like an unfastened screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 219-872-2198 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to get your attention it needs some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing might need to be greased. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also hear whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing whistling, Paniccia Heating & Cooling can help. It’s important to get loose ductwork repaired fast, since it can make comfort issues in your house and inflate your energy costs.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound usually means there’s an issue with your furnace’s blower. Turn off your furnace off immediately and reach our professionals at 219-872-2198 for support.
