Heating tuneup in Gainesville. Tested operation of 1 heat pump system. All components tested within normal manufacturing spec. Discovered system without drain line water safety to help prevent flooding in the case of common drain line clogs. System would greatly benefit from compressor saver hard start kit to reduce stress on compressor and reduce energy consumption on start up. Discovered organic growth inside system. Recommend ultraviolet light system to combat organic and viral growth in system and throughout the home. Added compressor saver to system and will revisit other repairs in the spring. System heating at this time
