Chris was great with the initial assessments of our desires and needs. Lenny examined every possible option and designed an incredibly efficient, high-quality system, including a very sophisticated reworking of the ductwork. Mike and Dylan were considerate and meticulous technical professionals. Anthony joined when appropriate, and Kristy’s oversight and responsiveness have no equal. The outcome is a whole new level of environmental comfort we didn’t know was possible. – John C., Portsmouth
