Heating maintenance in Cumming Georgia. Tested operation of 1 system. Heat pump would greatly benefit from compressor saver hard start kit to reduce stress on compressor and reduce energy consumption on start up which will extend the life of the system. System and home would also benefit from ultraviolet light systems to combat organic and viral growth in systems and throughout the home. Also recommend duct cleaning. System operation normal at this time. Installed compressor saver and signed up for maintenance membership.
