So what do I likely need for my 2-ton condenser unit in your estimation in Texas?
You need a furnace that moves 800 cfm's of air for your 2-ton a/c, not 1200, in Texas cooling is primary over heating, well it is in Houston. They might be able to lower the speed of the blower motor to achieve that 800 cfm, but why pay for a larger furnace you don't need.
It is very hard to read the numbers, but this is the best I could surmise on the inside units:
Does this help?
If you go to the PDF in your condenser link, it will show you the highlighted area at the bottom that you need 800 cfm's of air for the a/c. Look for the highlighted area, then look over to your left, see 800?
No problem that's what were here for, so your keeping the existing outdoor condenser, right?
No - we are replacing the condenser, coil, furnace - all the primary equipment (not the ductwork). Someone else posted asking about what equipment we currently have - that is why I posted that info.
We are leaning toward the single-stage Trane system I listed in my first post. But then it sounds like the furnace is not what we need according to you guys? So now - assuming the 2-ton single-stage system listed on the first post (accidentally listed a 2.5) is correct, what furnace do we need?
We are keeping the downstairs equipment as is. We are replacing ALL of the equipment for upstairs (except the duct work).
Ok on the same page now, sorry.
OPTION B - Trane single stage
Condenser Trane XR15
Coil - Trane AHRI
Furnace - Trane XT80
Ok here goes, sometimes the mfg. uses a higher cfm furnace to get to a certain seer,I am a Ruud dealer, and Ruud has done this in the past and I did not like it, but it was necessary to qualify for a tax credit. follow me so for? ok that might be fine if your in Arizona with a year round 25% humidity. If your shooting for better "humidity control" on a "single" stage unit, the more cfm's like the Trane 80 will provide will hurt your latent, lower cfm's = better latent/humidity control, more/higher cfm's is better for sensible heat, lights,people,cooking,etc. does this help.
