When your furnace is working correctly, it should deliver warm air without making too much disruption. While it’s expected to hear your furnace making noise as it begins running, other disruptions are showing your furnace requires immediate professional support.

Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making an atypical noise, our friendly heating pros are here to help with the best furnace repair in Norco and St. Charles Parish, Louisiana.

1. Furnace Making a Banging Noise

You might have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These involve gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s critical to book seasonal furnace maintenance with Mayeuxs AC & Heating. One of the jobs our technicians perform during this appointment is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can leak carbon monoxide, which is regularly vented outside. This dangerous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Mayeuxs AC & Heating urges you to turn it off and calling us at (985) 764-2426. Excessive natural gas in your furnace or a ruptured heat exchanger are critical issues that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide heated air around your home. If the ductwork wasn’t designed correctly or is getting old, it can make a lot of noise when your furnace runs. This can be the issue if your furnace makes a banging noise when it shuts off. Call Mayeuxs AC & Heating at (985) 764-2426 and we’ll determine the problem.

2. Furnace Buzzes Constantly

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

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or chilly air around your home, and a capacitor, which turns on the motor. If either of these pieces are fading, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be the result of something small, like a loose screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at (985) 764-2426 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to tell you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing could need to be lubricated. We are aware that maintenance often slips your mind, but our technicians can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still noticing sound, Mayeuxs AC & Heating can assist you. It’s essential to get loose ductwork repaired fast, since it can make comfort problems in your residence and increase your heating bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal racket usually means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and call us at (985) 764-2426 for assistance.
