I guess the best way is to just get the estimat first, then say you'll
sign it only if they do the load calculation. The estimate will
probably be overpriced anyway, so might as well get something extra out
of it.

How would a different sized system effect the existing ductwork though?

If you bought a higher efficiency system, you may need larger ducts
because I believe they need to push more air. That's what I've read
anyway. Don't feel bad, last time I had mine replaced I called three
people and none did a load calc. Next time I think I'll offer to pay
for the estimate if they'll do one and show their work.
