Heating maintenance in Roswell. Tested operation of 3 furnaces. Discovered upstairs system under firing. Discovered main level system with weak blower motor controller and failing condensate pump. Basement furnace operation normal. Systems and home would greatly benefit from ultraviolet light systems to combat organic and viral growth in the system and throughout the home and greatly improve indoor air quality. All 3 systems heating at this time. Calibrated upstairs furnace, replace main level condensate pump and blower motor controller. Signed up for maintenance membership
