I live on the east end of long island NY. Wish to install dx system in ground water which is about 54 degrees

That's wonderful, :),

I`m proud of you

OH! Was there a question to go with the statement?

Sorry what I am looking for is sizing information,

Here you go. Do your BTU calculations first then you will have a range to work with.

The calculation came out to 5 ton system, I feed to a 20x21 duct to the entire home.

I think something might be wrong with your calculations.

Stuffing 5 ton/60,000 BTU's into a 20X21 inch duct sounds a bit to small to me but I did not do the calculations.

I would check over you math to be sure. I like a quiet system.

Of course it is a split system with inline controls each for half the home
