When your furnace is operating correctly, it should deliver heat without generating too much noise. While it’s expected to catch your furnace making noise as it begins running, other disruptions are signaling your furnace requires immediate professional assistance.

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

1. Furnace Making a Banging Noise

You might have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These range from gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over the years, so that’s why it’s important to schedule annual furnace maintenance with Paniccia Heating & Cooling. One of the jobs our pros do during this work is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can emit carbon monoxide, which is normally vented outside. This toxic gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Paniccia Heating & Cooling advises turning it off and calling us at 219-872-2198. Too much natural gas in your furnace or a fractured heat exchanger are dangerous problems that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move warm air throughout your residence. If the ductwork wasn’t designed properly or is getting dated, it can be noisy when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Call Paniccia Heating & Cooling at 219-872-2198 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often indicates 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 isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or cooled air throughout your residence, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be related to something small, like an unsecure screw, or something serious, like a broken component. In either case, we advise shutting your furnace off and calling our heating specialists at 219-872-2198 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubed. We know 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 frequently due to an air leak in your ductwork. You may also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still hearing noise, Paniccia Heating & Cooling can help. It’s essential to get loose ductwork fixed quickly, as it can make comfort troubles in your house and inflate your heating bills.

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 noise frequently means there’s trouble with your furnace’s blower. Shut down your furnace off right away and call our professionals at 219-872-2198 for support.
