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?
regional building dept? where are you?
In my opinion I think they pretty mutch have to take any ACCA approved software (I think there are 5 now)
Elite and wrightsoft are both solid for anything you want to do.
there is a lot of buzz about aditek/ Accuload as being very fast but I get some indication that it might skip some of the finer points of load calcs. Personally, I give zero points for speed and everything towards accurate results. sloppy costs money and ticks people off!
PS- at that altitude you really need to watch your combustion on every system. I hope you are well trained in combustion analysis.
What lies behind us and what lies before us are small matters compared to what lies within us.
Two pressures, four temperatures = SUCCESS!

For HVACR Professionals:
darctangent, I am in Colo Spgs. I ended up getting the Wrightsoft, Wright-J Mobil, and will graduate to the Wright-Suite Universal in
a month or so. We usually end up setting the gas pressure between 3.0 and 3.5, keeping in mind the temp rise. What are you finding
That is one busy uncle
