When your furnace is operating like it should, it should provide warmth without generating too much disruption. While it’s expected to hear your furnace making noise as it turns on, other noises are signaling your furnace requires immediate professional assistance.

Here are some of the most common furnace noises and what they could mean. If your furnace is making an atypical noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Georgetown, Texas.

1. Furnace Making a Banging Noise

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

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over time, so that’s why it’s essential to set annual furnace maintenance with Miller Climate Control LLC. One of the tasks our professionals perform during this service is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can discharge carbon monoxide, which is ordinarily emitted outdoors. This dangerous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Miller Climate Control LLC urges you to turn it off and contacting us at 512-937-2001. Excessive natural gas in your furnace or a cracked heat exchanger are dangerous issues that should get immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move hot air throughout your home. If the ductwork wasn’t designed properly or is aging, it can be loud when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Miller Climate Control LLC at 512-937-2001 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box is loose, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or chilly air across your home, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be due to something minor, like an unsecure screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating professionals at 512-937-2001 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to alert you it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing may need to be lubricated. We know that maintenance often slips your mind, but our pros can get your furnace operating quietly again fast.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also be aware of whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still hearing noise, Miller Climate Control LLC can assist you. It’s critical to get loose ductwork repaired without delay, as it can result in comfort issues in your home and drive up your energy costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Switch off your furnace off now and contact us at 512-937-2001 for assistance.
