After opening access to the duct work found that the ducting was in very bad shape and in need to replacement. We can install dampers into the existing ductwork but the ducting will be damaged as areas are very hard to access and the ducting is already falling apart. After having our install manager do a job walk found that by redesigning the duct system and also adding a second register in the upstairs will help to fix the heat load issues upstairs. This estimate includes replacing 7 duct runs and adding an 8th to the upstairs. The install will also include 4 dampers to divert the air on the 4 main duct runs where needed.
