Brad, thought you might want to see this. Thanks Again
Having read several threads on this subject and specifically the one that Brad published inspired me to go for it. 95 degree days in the South and not being able to get the inside temp below 82 degrees after considerable work to seal ducts, installing sun blocking blinds, pillows in vents and minimizing door opening I decided it was time. The total job took about 2 days and $800.00, one day for wiring prep and one day to install equipment. Having the CCC 2 thermostat and 2 zones factory installed made the job easier. Zone 3 which I installed by removing the rear vent and installing the Dometic Brisk Air 2 15.0 with a non-ducted T-stat controlled air distribution box. I did a hybrid install by tying in the non-ducted air distribution box to the factory installed ceiling ductwork (not difficult) and the overall effect gave me more air without running additional ducts which would have been difficult. Available electric power is a non-issue, all 3 units running and the fans on hi and I wasn't close to maxing out. Indoor 68 degree temps are now achievable. Hardest part may have been running the telephone cable for thermostat com (4 wire flat cable) from zone 3 at the rear to zone 2 in the front bedroom (about 35 ft), make sure you follow wiring diagram for installing the connectors on the ends.
