You said it is humid, so you just answered your own question. A VS unit
can be set on real low and pull out the most humidity, a Vsdc unit can
pull only 100-120 watts on low and be left on continously. but get the
10yr warranty.

Of course it does. Why should he do someone elses homework for free?

RAJ, why do you care about seeing the actual calculations? If the end
result is that you need a furnace of XXXBTU, what difference does it
make how he got to that conclusion (or are you supposed to verify his
work?). If you were looking for more quotes you would then use the end
result to ensure that the other guys aren't off the mark, right?

So..what you are saying, if he gets a quote for $3000, one for $2500 and one
for $1000, then he should not care who actually did a load calc right?
Or..he gets 3 quotes for the same price.......but three diffent sized
units..he should just throw a freaking dart at the quotes right?

He needs to know who did the work, have them show him the calcs, and explain
how the calc, and the quote, compare, since there are times you will end up
rounding up, or down due to the final numbers.

Nope, that's not what I said.
The suggesting was that as long as the individual goes through the
process of doing the calculations then the result is what matters. At
the end of the day, unless they are completely incompetent they should
all come up with systems in the same area. If they don't (and claim
that they performed the calculations) then some of them are lying and
in this case, you wouldn't be able to tell who is lying until after you
signed with them.

But according to this guy (and you agreed with the result) he doesn't
get to see the calcs until after he's signed the work agreement. What
good are the numbers at that point?
