I downloaded the HVAC Calc program that I've seen mentioned here to size my AC unit & furnace. Can anyone tell me if this sounds correct?

I live in Indianapolis, summer temp of 91° & we keep it about 75° inside, the house is 106 years old but in the process of being updated, 2 story, 2000 sqft., R-19 exterior walls with Tyvek & vinyl siding, floor is over a crawl space with R-19 insulation, mostly carpet flooring, ceiling will be R-49 under ventilated attic. All new doors & windows. I hope this is enough info to get an idea if it's right or not.

The program spits out 21,324 heat gain & a 2 ton AC unit.

Thanks,
Dan

unfortunately only beginning. still in the demo stage. I figured it was probably right, I have just seen so many different recommendations that were much higher. Wasn't sure which to believe, but this looks like the most thorough.

Thanks!
