When your furnace is operating like it should, it should give warm air without generating too much disruption. While it’s expected to catch your furnace making noise as it starts up, other disruptions are indicating your furnace should get immediate professional support.

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

1. Furnace Making a Banging Noise

You may have a serious problem on your hands if you’re detecting 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 include gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy as time passes, so that’s why it’s important to schedule yearly furnace maintenance with Pepper AC & Heat. One of the things our pros do during this work is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes more time. The subsequent 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 released outdoors. This hazardous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Pepper AC & Heat urges you to turn it off and calling us at 940-202-1184. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous issues that necessitate fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move hot air around your house. If the ductwork wasn’t installed properly or is getting old, it can be noisy when your furnace is heating. This can be the case if your furnace makes a banging noise when it shuts off. Get in touch with Pepper AC & Heat at 940-202-1184 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually is telling you there’s 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 needs to be tightened, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or cooled air throughout your home, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be related to something little, like a loose screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 940-202-1184 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to tell you it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We know that maintenance often slips your mind, but our pros can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve looked at your vents but are still sensing whistling, Pepper AC & Heat can help. It’s essential to get loose ductwork taken care of without delay, as it can make comfort problems in your home and drive up your heating costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket frequently means there’s an issue with your furnace’s blower. Switch off your furnace off right away and call us at 940-202-1184 for assistance.
