When your furnace is running like it should, it should deliver warm air without creating too much disruption. While it’s expected to catch your furnace making noise as it starts up, other disruptions are signaling your furnace requires immediate professional support.

Here are some of the most common furnace noises and what they might be indicating. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Bryan, Texas.

1. Furnace Makes a Banging Sound

You may have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a few problems. These include gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s critical to schedule yearly furnace maintenance with Superior Air Repair. One of the jobs our professionals do during this appointment is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can leak carbon monoxide, which is normally vented outside. This dangerous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Superior Air Repair advises turning it off and reaching us at 979-775-8700. Excessive natural gas in your furnace or a ruptured heat exchanger are dangerous problems that should get fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move warm air throughout your house. If the ductwork wasn’t designed right or is aging, it can be loud when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Superior Air Repair at 979-775-8700 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the right voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cold air across your space, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be related to something small, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating pros at 979-775-8700 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to tell you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubricated. We are aware that maintenance often slips your mind, but our pros can get your furnace operating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also notice whistling while the furnace is working if a floor vent isn’t tight. If you’ve checked your vents but are still sensing sound, Superior Air Repair can help. It’s important to get loose ductwork fixed quickly, as it can make comfort troubles in your home and increase your gas bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket often means there’s a problem with your furnace’s blower. Shut down your furnace off instantly and call us at 979-775-8700 for help.
