When your furnace is working correctly, it should deliver warm air without generating too much noise. While it’s common to catch your furnace making noise as it turns on, other disruptions are indicating your furnace should get immediate professional help.

Here are some of the most common 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 Temple/Belton , Texas.

1. Furnace Makes Banging or Knocking Sounds

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

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over the years, so that’s why it’s critical to schedule annual furnace maintenance with Bell Air Conditioning Inc. One of the tasks our professionals do during this service is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can discharge carbon monoxide, which is regularly released away from your home. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Bell Air Conditioning Inc advises turning it off and reaching us at 254-307-9572. Excessive natural gas in your furnace or a cracked heat exchanger are critical issues that should get fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver heated air throughout your house. If the ductwork wasn’t put in properly or is aging, it can be noisy when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Contact Bell Air Conditioning Inc at 254-307-9572 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the correct voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or chilly air around your rooms, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be due to something small, like an unsecure screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating pros at 254-307-9572 for help.

4. Furnace Squeals

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

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still sensing whistling, Bell Air Conditioning Inc can assist you. It’s critical to get loose ductwork taken care of without delay, as it can result in comfort problems in your home and inflate your energy expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you hear 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 promptly and call our professionals at 254-307-9572 for help.
