For commercial, we use Trane Trace 700 and Carrier E20-II softwares, they are the standard in the industry.
As for residential, Manual J seems to be the best, it comes up with more reaslistic numbers. But Manual J cannot be trusted for Commercial calculations.
Using Trace or E20-II for residential will resuslt in oversizing the AC and undersizing the heat.
