"Hillside’s prompt and professional response was fantastic and always has been. We are very appreciative of the detailed diagnostics performed by the servicemen. This resulted in us choosing to have them install a brand new state-of-the-art heater in our home Their service and installation of the new heater was Very professional. Our new heater is functioning beautifully and we would not hesitate to recommend Hillside to everyone."
