I am bidding a Rheem split system against a competitor that is using Designstar. The house is 3000sf with half the house being basement of 1500sf. We are in Colorado at 7000ft, with humidity in the low 20s. We usually don't count the basement because it doesn't add much of a load. He shows the main level at needing a four ton system. I keep telling the owner that that is way to big
here! The Regional Bldg department only takes Wrightsoft and one other for serious designs in my area.
Anyone have any recomendations on a good/accurate manual J program that will run on an ipad 4?
