Why not go ahead and do THAT now too? It'd be cheaper than having them come
back and doing it later.....

Yes and no. In the case of my new setup, they are going to come back in
the spring to setup the AC, when it is warm out, since it isn't a good
idea to run it during the winter. Told me to call them, when the temps
get into the 70's for a couple of days in the spring.

They did install the line set, and everything else, but didn't run the
unit.

This is Turtle.

I would not change a coil inside and then do some major work later on the system
later with a condenser unit and tubing set. When you change one item in the big
three items like the condenser / tubing set / evaperator coil --- You change
everything as one item to have everything matching and set together as one unit.
You would not say hey put me a new trasmission in my car and next year I will
take that transmission and put it in my new car I get next spring. Don't piece a
unit when your going to buy the whole thing soon.

I agree that it's best to do everything at once, but what if that is not possible?
For example if a new furnace needs to be installed in the fall (as in you just
bought the house and it needs a new furnace) and you also want a new compressor unit
outside, the ambient temperatures may no longer be warm enough to run a compressor
until spring.

In this case, why would it not be better to figure out what size equipment you need
all around, install the coil now with the new furnace, and do the rest of the a/c
system in the Spring when the unit can be operated and tested. That eliminates the
need to rip apart the new furnace installation in the spring so that the evaporator
coil can be installed.
