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