When your furnace is running properly, it should provide heat without generating too much noise. While it’s common to catch your furnace making noise as it starts up, other disruptions are indicating 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 specialists are here to help with the best furnace repair in Temple/Belton , Texas.

1. Furnace Making a Banging Noise

You may have a critical problem on your hands if you’re hearing 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 range from gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s critical to set seasonal furnace maintenance with Bell Air Conditioning Inc. One of the things our techs complete during this service is clean your furnace’s burners. When this part gets grubby, you might hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can discharge carbon monoxide, which is normally emitted outside. This dangerous gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Bell Air Conditioning Inc advises turning it off and calling us at 254-307-9572. Excessive natural gas in your furnace or a ruptured heat exchanger are serious troubles that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air across your residence. If the ductwork wasn’t designed correctly or is getting dated, it can make a lot of noise when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Call Bell Air Conditioning Inc at 254-307-9572 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cooled air across your residence, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be due to something little, like an unfastened screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating pros at 254-307-9572 for support.

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 attempting to tell you it could use some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing could need to be lubed. We know that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also hear whistling while the furnace is working if a floor vent isn’t secure. If you’ve checked your vents but are still noticing whistling, Bell Air Conditioning Inc can assist you. It’s essential to get loose ductwork repaired fast, because it can create comfort troubles in your residence and inflate your utility expenses.

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 sound frequently means there’s an issue with your furnace’s blower. Switch off your furnace off right away and contact our pros at 254-307-9572 for support.
