Heating maintenance in Alpharetta Georgia. Tested operation of 2 systems. Discovered upstairs blower motor controller weak and outside of manufacturing spec. Both systems have no secondary water safety. Both systems would greatly benefit from ultraviolet light systems to combat organic and viral growth in systems and throughout the home. Both systems would also greatly benefit from compressor saver hard start kits to reduce stress on compressor and reduce energy consumption on start up which will extend the life of the systems.
