Trane XR15 3 Ton AC Fan Noise
Upon starting, my newly installed Trane XR15 AC compressor cooling fan (outdoors)makes a high-pitched whirling sound which disappears once fan is at full speed. It happens at each cycle start. My installer replaced the fan but the new fan makes the same sound. The installer claims he called Trane and they stated it was caused by the fan pitch. The fan is a new design, apparently.
I called Trane but they told me to call another installer for another oppinion. ??
Has anyone had this fan noise experience?
