Our furnace quit on a Friday evening. Monday morning they called, were out Tuesday, made sure we had an alternative source of heat providing portable heaters as needed. Professional installation fitting both our personal needs and their work load. Proposal and final bill were spot on, no added charges. They worked all the rebates and warranty registration. Additionally in the first week our thermostat was not working properly. They followed me home from the office and fixed the thermostat on site same day. This is what customer service should be. Thank you for your excellent service and workmanship.....Customers for life!!! John and Maureen
