When your furnace is working like it should, it should provide warm air without creating too much disruption. While it’s expected to catch your furnace making noise as it starts up, other sounds are signaling your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they might be signaling. If your furnace is making an odd noise, our friendly heating specialists are here to help with the best furnace repair in Michigan City, Indiana.
1. Furnace Makes Banging or Knocking Sounds
You may have an urgent issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These include gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s critical to schedule routine furnace maintenance with Paniccia Heating & Cooling. One of the things our professionals complete during this work is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can discharge carbon monoxide, which is normally vented outdoors. This toxic gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Paniccia Heating & Cooling urges you to turn it off and reaching us at 219-872-2198. Significant natural gas in your furnace or a fractured heat exchanger are hazardous issues that should get prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move heated air across your home. If the ductwork wasn’t designed properly or is getting dated, it can be noisy when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Contact Paniccia Heating & Cooling at 219-872-2198 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually 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 proper voltage. If wires or the box needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or cold air throughout your house, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace switches on.
3. Furnace Rattles
If your furnace is making a rattling noise, it could be related to something little, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and calling our heating specialists at 219-872-2198 for assistance.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again fast.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, Paniccia Heating & Cooling can provide support. It’s essential to get loose ductwork fixed without delay, as it can create comfort troubles in your home and inflate your utility bills.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise usually means there’s an issue with your furnace’s blower. Switch off your furnace off right away and reach our professionals at 219-872-2198 for assistance.
