I’ve come to expect great service from Moon Air, today was no exception. Liz was courteous, knowledgeable and trustworthy. He took the time to explain each detail of the routine maintenance performed, made recommendations for the most cost effective approach to replacing part of our system that is due for replacement and even contacted the existing manufacturer to see if anything was still under warranty. This level of service is extremely rare today and why I stick with MoonAir. Highly recommend both Koz and this company. Shop local!
