Just put the finishing touches on a new Trane XR16 installation in Granbury. Their old unit finally gave up the ghost after nearly 20 years of service - can't complain about that kinda longevity! Removed the old system and upgraded them to a 16 SEER unit that'll cut their cooling costs considerably. Had to modify some of the existing ductwork and electrical to accommodate the new system, but everything went in smooth. Pressure-tested the lines, pulled a proper vacuum, and charged the system to manufacturer specs. Ran it through a full test cycle and it's cooling like a champ. Walked them through the new programmable thermostat features - she was mighty excited about the WiFi capabilities.
