I am interested in replacing my Rheem Condensing unit model #CFF-0250-
RFVC. I have a Goodman A30-10 air handler. Does anyone know what
condensing units would be compatible with my Goodman air handler. I
was thinking that the outside unit is a 2.5 ton unit and my house is
1,500 sq/ft. I would like to jump up at least 1/2 a ton if at all
possible on the condensing unit. What do ya'll think?
Thanks

I think you are about to make a clusterfuck into a bigger one.
1500 sq/ft means absolutely NOTHING.
WHY not do a load calculation and install a PROPERLY sized unit???

Tight budget and I don't want to replace the air handler if I don't
have to. I have A/C resources but am not a contractor. Are you
telling me the system is already screwed?? What is the PROPER unit
size? 1 ton = 500sq/ft?? Am I wrong? I know there are other factors
that can effect that calc but saying there are no other factors what
do ya think?

My thinking HAS NOT changed any...
Do a "load calculation", or settle for the quality that you pay for.
Low cost will equal a screwed up system. One that will not only affect your
comfort, but will cost you more in operational cost. You'll NEVER be happy
with it's performance, as you will be having it serviced constantly.
You have a choice, do it *right* now or do it twice. Doing it properly the
first time is a WHOLE lot cheaper.
As far as 1 ton per 500 sq/ft... do you think someone in NY, SD, or CANADA
will need as much cooling as someone in FL, TX or AR?
What if one has 2 x 4 construction vers 2 x 6?
What if one has R13 walls & R19 ceiling insulation vers R19 walls & R30
Ceiling?
What if one has a basement and the other is on a concrete slab?
What if one has twice as many windows?
What if one has sky lights?
What if one has an attached garage?
What if one has a lot of shade?
What if one likes it 68 and the other likes it 78?
The list just keeps going...
First step,
GET A LOAD CALCULATION!!!!!!!!!!!!!!!!
