Upon my arrival I evaluated 1 Bryant gas furnace system. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Found the return flex and supply ductwork to be in bad shape. Multiple holes and rips in flex duct, and old metal ductwork insulation wrap is tatterd and falling off in multiple locations. Our comfort specialist will be coming by the give a quote on repair or replacement of listed issues.
