When your furnace is operating properly, it should give heat without creating too much disruption. While it’s normal to notice your furnace making noise as it begins running, other sounds are showing 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 odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Temple/Belton , Texas.

1. Furnace Makes Banging or Knocking Sounds

You may have a serious issue on your hands if you’re noticing 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 issue.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty as time passes, so that’s why it’s important to book annual furnace maintenance with Bell Air Conditioning Inc. One of the things our professionals do during this appointment is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can emit carbon monoxide, which is normally vented away from your home. This toxic gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Bell Air Conditioning Inc urges you to turn it off and contacting us at 254-307-9572. Excessive natural gas in your furnace or a broken heat exchanger are critical problems that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move warm air across your home. If the ductwork wasn’t put in correctly or is aging, it can be noisy when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Bell Air Conditioning Inc at 254-307-9572 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently means there’s an electrical issue, 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 notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or chilly air throughout your house, and a capacitor, which triggers the motor. If either of these parts 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 can be related to something little, like an unfastened screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 254-307-9572 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to alert you it could use some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be greased. We realize that maintenance often slips your mind, but our techs 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 frequently due to an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still hearing sound, Bell Air Conditioning Inc can assist you. It’s essential to get loose ductwork fixed without delay, as it can result in comfort issues in your home and drive up your gas costs.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound frequently means there’s a problem with your furnace’s blower. Switch off your furnace off right away and call our pros at 254-307-9572 for support.
