RVJim and a few others here are spot on. You can easily go to the Sumter County website and look at your blueprints and Manual J calculations for YOUR home. A tad undersized is better than oversized for the reasons many have stated. If you cool down the temp in your home w/o allowing run time to get the humidity down you will get what they call, "Meat locker syndrome" and your home will feel cold but clammy. You do not want short cycling. The most common complaint we hear is temperature variations in rooms, which most often caused by poor air balancing and missing/displaced insulation. Hope this helps!
