User reviews

Overall a nice idea but the implementation is a bit careless

Although skylights apparently contribute to the total heating and cooling loads, they are listed as contributing zero in HTML summary and skylights tab. Also, the screen for saving the summary appears and disappears before the user can pick which folder to save it in. Data entry is a bit closer cumbersome because even after entering a value, it might disappear if one neglects to hit tab or return. Little things like that make the app seem less polished than it could be.

Program will not load screens

I get nothing but the demo screen. No way to enter new loads.

Waste

Was not worth the 50 bucks. Don't waste your money!!!!

Pretty decent app

Fairly simple to use especially on site. I've had numerous load programs and this does work properly. My only reason for three stars is there is no specific construction data for foam insulation. Most popular load programs have specifics for this. I have called and talked to these guys and they say just choose the R value. Well that's what the program is supposed to do after you choose thickness and poundage of the foam being used as well as closed cell or open cell. I certainly wouldn't pay more than 50 bucks for this program. Just saying.

Overpriced

This app puts a lot of emphasis on some less-than-essential data and graphs that, while visually appealing, provide mostly irrelevant information.

The interface is attractive, but data entry is TEDIOUS and yields fewer results than you'd expect from a $35 app ($50 if you bought it when I did) into which you've just spent 25 minutes scrolling, tapping, sliding, and typing.

If you're only interest is impressing customers with your tech toys, go for it.
