"PIC really offers the sort of trades service we used ro find in Wisconsin communities. Scott explained different options with newer technologies before letting me decide what was right for us and our pocket book. We've had him do both AC repair work and installation and we're planning a garage heating system this fall as well. Fast, knowledgeable, and respectful of our circumstances. I highly recommend PIC for any HVAC need, large or small. I've talked to many others who have had the same experience with them as well!"
