I had an issue with my water cooled A/C compressor, texted Mike, the boss, himself on his cell phone. In turn his office scheduler called me to set up an appointment for the day after next, as I didn't have time on the very next day. Mike came by himself within the requested time window. His office kept me apprised of his likely arrival time. Mike provided a temporary fix to the problem as he needed to order a part first. This part will be installed the next time when Mike comes by to winterized the system. There is no urgency at the present time. Since it is water cooled (more energy efficient) it needs to be drained in late fall to prevent any damage from freezing water. Airsmiths installed my system quite a few years ago and did a thorough review of my home. This included improvements to insulation, new hardware, and many other things. It has dramatically lowered the cost of heating or cooling my home, not to mention making it much more comfortable. I highly recommend AirSmiiths. It is a great company.
