OK, I have a question about the 'mythical' man J. I say mythical because for myself, and it seems lots of others, finding a contractor to do a proper load calc is impossible.
Say you are going with VS indoor and 2 stage outdoor gear, higher end. Only available in 1 ton increments. Do you go for 2 tons, with the idea that if you end up short you swap out the outdoor unit for a 3 ton model the next year(yes, you picked an indoor unit and sized the cooper with the thought that this might happen) OR do you go for a 3 ton unit with the idea that if you are over you install a whole house dehu to drop the humidity.
I know there are holes in this scenario, but thought that if it generated some comments from the HVAC pros on the site it might be helpful to homeowners.

Thanks in advance!
