When your furnace is operating correctly, it should give warm air without making too much disruption. While it’s expected to notice your furnace making noise as it turns on, other disruptions are signaling your furnace needs immediate professional help.

Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making a weird noise, our friendly heating professionals are here to help with the best furnace repair in East Bernard, Texas.

1. Furnace Makes Banging or Knocking Sounds

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

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s critical to set routine furnace maintenance with E.B. Air. One of the jobs our pros do during this appointment is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can leak carbon monoxide, which is normally released outdoors. This hazardous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, E.B. Air recommends turning it off and contacting us at 979-335-4262. Too much natural gas in your furnace or a broken heat exchanger are serious problems that should get fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver heated air around your residence. If the ductwork wasn’t designed properly or is aging, it can be noisy when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Call E.B. Air at 979-335-4262 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 frequently means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the right 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 has a blower motor, which moves warm or chilly air throughout your space, and a capacitor, which starts the motor. If either of these components 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 could be due to something little, like an unsecure screw, or something major, like a broken part. In either case, we advise shutting your furnace off and contacting our heating specialists at 979-335-4262 for assistance.

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 could use 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 realize that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again fast.

5. Furnace Whistles

When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing whistling, E.B. Air can help. It’s critical to get loose ductwork repaired quickly, as it can result in comfort problems in your home and drive up your gas bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound usually means there’s an issue with your furnace’s blower. Shut down your furnace off instantly and contact our professionals at 979-335-4262 for assistance.
