For the super tune-up I inspected the air handler and condenser, all equipment was measuring within manufacturer specs and running well. Well inspecting the air handler I noticed there was no water safety on either drain line or in the overflow pan, I recommend to the customer getting some sort of water safety to prevent water damage to their ceiling. Lastly I recommend a compressor saver and surge protection for the home to increase the longevity of their system as well as protect it from any surges or lightning strikes.
