Recent Review: I interviewed many contractors before hiring Daniel. Only Daniel gathered the numbers (rooms sizes, window types and sizes, insulation type) and ran all calculations to properly size the furnaces, A/C condensers, duct and vent sizes. All other companies just guessed what I needed, and they were all wrong. I selected Amana equipment, 16 SEER condensers, and 96% AFUE furnaces. They come with a lifetime warranty on the scroll-type, dual speed compressors and heat exchangers. Only Amana offers such a warranty. If a compressor or a heat exchanger breaks in the first five years, Amana will replace the entire unit with a new one. Another first. Back to Daniel, he spent over a month redoing the system from scratch. His work was absolutely first class, and the result is a fantastic, perfectly-sized dual system that cools my house in no time without seeing much difference in my electrical bill! Daniel is also an excellent plumber.
