About five years ago we needed a new furnace and decided to also have air conditioning installed. We got estimates from five or six different companies. Perry's estimate fell in the middle in terms of price but we got the best feeling from their estimator. They arrived to installed the furnace and air conditioning the day I went into labor! We ended up leaving them with our house in their hands while I went to the hospital to have our baby. And hey, Lute Olson endorses them so they must be good, right?
