An efficiently operating air conditioner should produce minimal sound beyond a soft hum. However, when abnormal noises begin—such as rattling, buzzing, or screeching—they often indicate mechanical or electrical issues within the system. In our experience with AC repair in Flower Mound, TX, we can say with certainty that identifying these sounds promptly can help prevent further damage and extend the unit’s lifespan.
Banging or Clanking
If your AC is making a loud banging or clanking noise, it could mean a loose or broken part inside the compressor. This might also indicate the indoor blower or outdoor fan blades are out of balance and hitting other components. Either way, it’s not a noise to ignore—call an emergency AC repair technician to inspect it ASAP.
Hissing or Bubbling
A hissing sound could point to a refrigerant leak, which is a serious problem. Refrigerant helps your system cool the air, and a leak not only reduces performance but can also be harmful to your health. Bubbling noises often accompany hissing and could be caused by air trapped in the refrigerant line. This is definitely a job for a reputable AC repair company.
Clicking
It’s normal to hear a click when your AC turns on or off, but continuous clicking is a red flag. It could indicate a problem with your thermostat or electrical components. Don’t let this one slide—it might be a simple AC maintenance fix, but it can turn into something bigger if ignored.
Screeching or Squealing
High-pitched screeching usually signals a problem with the fan motor or a worn-out belt. While not immediately dangerous, it can affect the efficiency of your system and lead to bigger mechanical problems over time. Be sure to schedule professional AC repair services ASAP.
