When your furnace is running properly, it should provide warmth without generating too much sound. While it’s normal to hear your furnace making noise as it begins running, other sounds are indicating your furnace needs immediate professional support.

Here are some of the most frequent furnace noises and what they could mean. If your furnace is making an odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Norton, Virginia.

1. Furnace Making a Banging Noise

You may have a critical situation 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 several problems. These include gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy as time passes, so that’s why it’s essential to schedule annual furnace maintenance with HCE Systems. One of the tasks our professionals perform during this work is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can leak carbon monoxide, which is ordinarily vented away from your home. This hazardous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, HCE Systems recommends turning it off and reaching us at 276-302-0076. Significant natural gas in your furnace or a fractured heat exchanger are critical troubles that require immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver hot air around your house. If the ductwork wasn’t installed properly or is getting dated, it can be loud when your furnace runs. This could be the problem if your furnace makes a banging noise when it shuts off. Contact HCE Systems at 276-302-0076 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box is loose, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or cold air around your house, and a capacitor, which starts the motor. If either of these parts are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be related to something little, like an unfastened screw, or something major, like a broken component. In either case, we advise shutting your furnace off and contacting our heating pros at 276-302-0076 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to get your attention it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing may need to be lubed. We are aware that maintenance often slips your mind, but our professionals can get your furnace operating quietly again fast.

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 might also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still noticing sound, HCE Systems can help. It’s critical to get loose ductwork taken care of quickly, as it can result in comfort issues in your residence and inflate your gas bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Switch off your furnace off right away and reach our pros at 276-302-0076 for help.
