Excellent responsiveness and good quality communication during the proposal phase. On time project start and mostly according to plan installation. I was unable to be present at the end of the installation and found when I returned that the system was not working. This required a re-visit by an installation foreman to correct the situation and brief me on the system’s use. A return visit by the electrician was also necessary to check out and confirm functionality of the backup system. Communication about all this at the end of the project could have been better.
Follow up: service call when one ac unit failed. Very prompt response and the issue was resolved within a couple hours. Poor wiring connection does raise a question about the quality of the original work.
