2 years ago I got a brand new Carrier 10 Seer AC on the roof.

Now, the furnace and evaporator is at the end of its life so it needs to be
replaced.

But I heard that according to the new law since 2006 only 13 Seer and above
are available.

Does that mean I have to get rid of this almost new AC condenser and change
out everything for 13 Seer or above?

Or can I just change out the interior components with 13 Seer equipment,
will that work with my existing 10 Seer Carrier? I think it's 2 ton.

No, you will not have to replace your condenser. A new furnace and
evaporator should work fine with it.

15 years ago I put in 14 seer, keep your old unit, a new 16 seer would
cut your electric in half.

You will be OK but I would recommend that you have an expansion valve in the
new evaorator coil.

OP may not get good warranty using existing parts. I would price both
ways and decide then

You will be OK but I would recommend that you have an expansion valve in
the new evaorator coil.

What would the expansion valve do in this mixed configuration?

That is good news! Can I mix and match brands, for example use Trane coil,
air handler, and furnace with the Carrier condenser? In other words can I
use "just about any" indoor equipment bundle with the 10 Seer rooftop AC
unit? Is is mostly the indoor portion that affects the efficiency the most?

the outside unit largely sets efficency. new outer uits are much
physiically larger

thanks... now, that's what I'd really like to find out. If I use my
existing 10 Seer condenser with a 15 Seer indoor coil, should I expect to
get somewhere closer to 11 Seer, or 14 Seer, or somewhere in-betwen when I
mix & match like this?

A 15-SEER evaporator will have a lot more refrigerant volume compared to
the 10-SEER condenser, that would require a lot more total refrigerant.
That is a volume imbalance between the condenser & evaporator, - an
imbalanced refrigerant system won't operate efficiently.
A balance between the indoor & outdoor units plus the indoor airflow
determine efficient operation.

A 15-SEER evaporator will have a lot more refrigerant volume compared to
the 10-SEER condenser..
Make sure it has a TXV refrigerant control metering device.

determine efficient operation.
It does NOT work the other way around with a 15-SEER condenser & a
10-SEER evaporator.
