The job included installation of 3 motorized sky llghts. I had been told that they would operate the same as the previous ones, which employed a simple thermostat to open and close them. What I wound up with was a system which used wireless controls and wifi. There was no manual or instructions for using the system. I can't even figure out how to set the temperature control.
I had some trouble getting calls returned.
Communicating with the crew in English was iffy.
We chose Global because of good experience with a previous job installing a metal roof.
