When your furnace is working like it should, it should give warmth without making too much sound. While it’s expected to catch your furnace making noise as it starts up, other disruptions are indicating your furnace requires immediate professional assistance.

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

1. Furnace Makes a Banging Sound

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

Banging Sounds Coming from Your Furnace

Your heating system gets dirty as time passes, so that’s why it’s important to set routine furnace maintenance with Evenaire Heating & Air Conditioning. One of the tasks our pros do during this appointment is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes longer than normal. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can leak carbon monoxide, which is regularly released outdoors. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Evenaire Heating & Air Conditioning urges you to turn it off and calling us at 512-355-1482. Significant natural gas in your furnace or a cracked heat exchanger are critical troubles that require immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air across your home. If the ductwork wasn’t designed correctly or is getting dated, it can be noisy when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Evenaire Heating & Air Conditioning at 512-355-1482 and we’ll pinpoint 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 indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the correct voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or cold air around your residence, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be the result of something little, like a loose screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating pros at 512-355-1482 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

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

5. Furnace Whistles

When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing sound, Evenaire Heating & Air Conditioning can assist you. It’s critical to get loose ductwork fixed quickly, as it can create comfort problems in your residence and increase 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 usually means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and reach us at 512-355-1482 for help.
