Corrections and additions..
I have a 3.0 ton and a 2.5 ton, mistake was that I thought I had a 3.5 and a 2.5.
Here is a breakdown:
Lennox AC Unit: 10ACC-036-230-02 (3.0 Ton 10 Seer)
Lennox Furnace: G40UH-36B-090-09 (1/3 HP Blower)
Lennox AC Unit: 10ACC-030-230-03 (2.5 Ton 10 Seer)
Lennox Furnace: G40UH-48B-090-07 (1/2 HP Blower)
So the furnace units seem to be correct for the job...the larger HP blower unit is working for the second floor. That makes sence because it needs to force the air up to the second floor from the basement.
So the question that I am still looking for the opinions on..should the 3.0 Ton Unit be upstairs or downstairs based on:
2.5 ton of AC cooling ~2195sqft of upstairs with attic above with "mid-level" dens (one with attic above and the second halfway underground).
3.0 ton of AC cooling ~1475sqft of downstairs with a kitchen and 9ft ceilings throughout.
All walls, windows and insulation being basically equal.
I have a call into the builder to have them check out the way it should be. Since I was off by .5 tons the gap on the differance has closed some...so it might come down to sizing based on other things that are known to them and not to me.
