SWEEEEEEEETTTT!!!!!!!!!!
Is the compressor a two stage or single stage?
That is a nice high SEER rating. Is it a pure central Air unit or is it a Heat pump ????
I have a heat pump. One thing I was told was that the newer Freon charged systems require larger ducts because they push more air volume. Don't know how true that is because I left mine alone it has worked extrememly well over the past couple seasons.
Example: MY home is entirely electric everything. No gas.
In the dead of a bone chilling winter, with our electric water heater , washer and dryer, Stove, and of course HEATPUMP with a very large KW resistance coil for backup, the average electric bill for us was under $165 for a month.
This summer in blazing heat and humidity here we are spending about $95.00 for electric. Very efficient...
GOOD LUCK with your very cool project. Sounds really nice and I suspect you should take a little gratification of doing the work yourself and saving money. Always a plus!!!

Best to you,
