    The measurements taken at the AHU were taken directly ABOVE the AHU, so any heat generated by the fan is already largely reflected in the readings.

  20. Troubleshot My System, Need Parts Guidance

    Okay, thanks guys, that "blistering" is likely just traces of normal copper/weld oxidation I'm guessing.
