We had the furnace system replaced in our home. Several problems arose during the installation, requiring two full days to complete the work. The two employees worked non-stop for two days, with little break, to get the heating system up and running. They took great care not to impact the interior of the house, plus left the areas where the duct work passed through the walls in better shape then prior to the work. Please pass on our appreciation to both men. Also, thank the individual who did the initial assessment for his honesty in explaining our alternatives and the possible outcomes. The product installed works quieter and seems to be more efficient. So far so good. Thanks again.
