A/C replacement with Trane 16 seer system

We replaced 30 year old A/C system with a new Trane 16 Seer outdoor condenser in the snow! We also installed a new digital energy star WiFi Nest Learning Thermostat. Customer gets a $100 rebate and can control the heat and A/C from any computer or smart phone. We also are installing exhaust ductwork off the customers existing microwave. We are running 6″ duct up though the cabinet into the attic and running over the the eave and installing a vent to the outside. Customer will get a $400 rebate from coolsmart for the A/C install.
