Last summer the univent in my new office was leaking water down the wall, Christian looked at it and determined that there was a hole in the condensate pan. The WO was transferred to a different unit who made a couple attempts to repair the pan with no luck. No more action was taken until a week ago when Christian noticed that it was still not fixed. Christian took it upon himself to fix the problem. He found a condensate pan that was in good shape, replaced mine, and found (and got approved) a source to get replacement pans. I am most impressed by his customer service, and the fact that he took ownership of the problem and worked very quickly to get it repaired before AC season was back upon us. I appreciate his outstanding work ethic and ultimately that's what makes him a star.
