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.



Then don't run the compressor, silly!

You don't need to run it to install it.

So what's the point of not waiting until the spring to install the outdoor unit,
since the contractor will have to return to get the proper refrigerant charge
and check out the system when it is operating anyway.
