When your furnace is running correctly, it should deliver warm air without creating too much sound. While it’s common to catch your furnace making noise as it starts up, other disruptions are showing your furnace requires immediate professional assistance.
Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making an atypical noise, our friendly heating professionals are here to assist with the best furnace repair in Pflugerville, TX.
1. Furnace Making a Banging Noise
You may have a serious issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a few problems. These include gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over the years, so that’s why it’s essential to set routine furnace maintenance with Evenaire Heating & Air Conditioning. One of the things our professionals complete during this work is clean your furnace’s burners. When this component gets dirty, you could 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 heat. Any cracks in it can emit carbon monoxide, which is normally emitted outside. 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 advises turning it off and reaching us at 512-355-1482. Excessive natural gas in your furnace or a cracked heat exchanger are critical issues that should get fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air throughout your residence. If the ductwork wasn’t designed correctly or is aging, 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 Evenaire Heating & Air Conditioning at 512-355-1482 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or chilly air around your house, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something minor, 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 512-355-1482 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent is loose. If you’ve examined your vents but are still sensing whistling, Evenaire Heating & Air Conditioning can provide support. It’s important to get loose ductwork fixed fast, since it can create comfort issues in your house and drive up your utility bills.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Turn off your furnace off promptly and call our pros at 512-355-1482 for help.
