When your furnace is working properly, it should provide warmth without making too much disruption. While it’s common to catch your furnace making noise as it begins running, other disruptions are showing your furnace should get immediate professional help.

Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to help with the best furnace repair in Longview, Texas.

1. Furnace Making a Banging Noise

You could have a critical issue 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 increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s important to set routine furnace maintenance with Goode Bros AC & Heating. One of the things our technicians do during this appointment is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise after ignition is delayed. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can emit carbon monoxide, which is regularly emitted outside. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Goode Bros AC & Heating recommends turning it off and calling us at 903-284-2612. Too much natural gas in your furnace or a fractured heat exchanger are critical troubles that should get fast service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide heated air across your house. If the ductwork wasn’t put in right or is getting dated, it can be loud when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Call Goode Bros AC & Heating at 903-284-2612 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace relies on an internal transformer to operate 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 has a blower motor, which distributes hot or cold air throughout your space, and a capacitor, which triggers the motor. If either of these pieces are failing, 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 related to something minor, like an unsecure screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 903-284-2612 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to get your attention it requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing could need to be lubricated. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still sensing noise, Goode Bros AC & Heating can assist you. It’s important to get loose ductwork fixed fast, since it can make comfort troubles in your residence and inflate your gas costs.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise often means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and reach our professionals at 903-284-2612 for help.
