Reviewed home to determine a list of priorities to ensure comfort and increase efficiency. There is no insulation on 2nd floor walls, no blocking to floors, and minimum knee wall insulation. Ductwork connections are very poor condition and should be replaced and trap needs to be installed on drain. Recommend full system analysis and tune up to ensure system is working properly. Also recommend adding another supply and return ductwork to second floor at same time home performance work is completed.
