Completed start up on upstairs system. Installed T6 thermostat and programmed it for straight ac electric heat. Found light switch acting as disconnect for AHU due to light switch only breaking 120v on 240v system the system is still getting 120v making it a safety issue. Found outdoor disconnects fuse where missing. Bypassed disconnect to complete start up. Talked to Jacky and he said to replace the indoor disconnect for the agreed $250 and he would take care of the outdoor disconnect. Started system up found refrigerant pressures were slightly low added R410A, pressures and temperatures are now appropriate for indoor and outdoor weather conditions temp split 18*. Set thermostat to 72*

Installed new 6” duct to sun room. Replaced old ductwork to sun room. Reconnected 7” duct to upstairs bonus room
