I replaced my old AC/furnace with a heat pump system. Nhanh and John had the pleasure of removing the old system and installing the new heat pump while I was at work and my wife was home. The outside temperature was in the mid 90's. After the installation, Nhanh found that my thermostat would not work with my heat pump and replaced it with another. Using the coolest manifold I've ever seen, he took his time, and it took awhile, to measure in the refrigerant while he cleaned up, insulated the new transition, etc. He tested the heating mode, as well as the cooling mode. I am very happy with the installation and the product.
