When your furnace is running properly, it should deliver warm air without making too much sound. While it’s normal to hear your furnace making noise as it starts up, other disruptions are indicating your furnace should get immediate professional assistance.

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

1. Furnace Making a Banging Noise

You may have a critical issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean 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 gets filthy as time passes, so that’s why it’s important to schedule routine furnace maintenance with Miller Climate Control LLC. One of the things our techs complete during this service is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can emit carbon monoxide, which is normally released away from your home. This hazardous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Miller Climate Control LLC recommends turning it off and reaching us at 512-937-2001. Significant natural gas in your furnace or a fractured heat exchanger are serious issues that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air across your house. If the ductwork wasn’t designed properly or is getting dated, it can be noisy when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Call Miller Climate Control LLC at 512-937-2001 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often 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 right voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or cold air across your rooms, 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 Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may 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 calling our heating pros at 512-937-2001 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to tell you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance often slips your mind, but our technicians can get your furnace operating quietly again fast.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing sound, Miller Climate Control LLC can help. It’s essential to get loose ductwork taken care of without delay, because it can result in comfort problems in your residence and inflate your gas costs.

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 trouble with your furnace’s blower. Turn off your furnace off immediately and reach us at 512-937-2001 for support.
