    Homeowners version

    I use HVAC-Calc. They have a homeowners version for something like $49.


    The guy that designed the program is usually the guy that answers the phone when you call. Don Sleeth Great guy and great support through the years.

    I used HVAC-Calc to do my building.  Bought the 3 month license and learned how to use it during my commuting times on USAir.  It calculated 160,000 BTU for my design conditions and that  is what I installed.  This was half the estimates provided by the local contractors and was the correct number.

    It allows you to play what-if and see for example how more insulation on the North wall will affect the heat loss.  Or insulating the basement walls.

    Worth getting the program in my opinion.
