We were extremely satisfied with the Tech (Ken S) that installed our Building 36 thermostats. He was very knowledgeable about the product. He was also very patient to explain the system to us. As we always do, we will recommend E F Winslow to others . The Building 36 system was recommended by your heating Tech (Carl) during our fall service visit. We are very happy with the service and the product. Jean and Joe Thiel
