	Here are some comments from HVAC-Calc users: "The HVAC-Calc program is more of a brass tacks approach without the fluff." "The data entry is straight forward and follows a logical path." "I was looking for a better loss/gain program. Demoed the XXX program... consider it junk. Bought XXX softwares program at the recommendation of local Wholesaler... Another piece of junk. Loads are WAY OFF using that program. Downloaded your program... LOVED IT... Bought it" "It was very easy to use after a few minutes of getting familiar with it." "X_________X has too many buttons and icons. Again, lots of fluff and colors, but harder to use in my opinion." "The wall entry feature is very handy in HVAC-Calc, especially when you have multiple wall constructions as I did." "the data for my house input nicely, the reports popped up nicely, and it has yet to gpf or bust -- wow!!" "For me, your program was easy to figure out and use. I used the room-by-room approach when it probably would have been easier to do the whole-house method. Your sample house calculation was a useful tool for me to verify that I was doing things correctly." "I downloaded at least 6 demos and yours was the easiest to use by far and the easiest to get the right answer." "Your program seems to me to be very user friendly. Keep up the good work."
