• Allows Heating only, Cooling only, or both at Project, Zone or Item level
• Project report can be viewed, emailed as PDF, or printed with AirPrint
• Outdoor Design Weather Database over 1800 cities included with provision for custom values
• Construction Type database with several hundred types
• Save money - purchase once and use the same app license for iPhone or iPad (of course the database will be different)
HVAC Buddy Load Calc allows you to enter all the construction characteristics relating to heat gains and losses for the purpose of calculating total building heating and cooling loads. In addition to number keypad every numeric inout also has Plus [+] and Minus [-] buttons for quick changes.
Zone and Room Level construction items:
• Above Grade Walls
• Basement Walls
• Partition Walls
• Wood and Metal Doors
• Partition Ceilings
Zone Level Construction Items:
• Blower Heat
• Internal Gain
Opening areas for walls with attached doors and windows are automatically calculated and subtracted. In addition, if you elect to specify a wall orientation windows associated with the wall can optionally inherit the wall orientation.
Create (copy) new Projects from the Default project or create template projects to jump-start calcs for structures typical to your area. Create (copy) new loads from Default Project or any other load within the current Project. Mark Projects as "Template" Projects to have them appear first when creating new projects.
Included are three "starter" customers:
• "Vatilo" is used for the example projects modeled after the MJ8 sample project
• "Scratchpad" use for testing and training
• "Default" holds the "Default" Project
The Default customer contains one Default project with only one of each construction type. Each of these types are the "master" for creating new entries.
The "Vatilo" Projects are similar Homes in three stages. The first stage "Home - Unsealed Ducts" is a simple block load with inefficent ducting. "Home - Improved Ducts" is exactly like "Home - Unsealed Ducts" but shows reduced cooling loads by improving duct seal and insulation. "Home - with Rooms" is a similar structure with room by room loads. As projects are organized by customer you'll easily see all projects and track existing vs potential upgrade projects for a customer.

Ratings and Reviews
Not good or easy
Just downloaded today. Not very user friendly. Just tried to do my home before I tried for customer. Very disappointed. Not even sure if calculations are accurate.
Very detailed and accurate load calculations!
Check this against my heat load calculations, very happy with this app.
I'm especially happy with the professional looking reports I am able to print from this app.
I can't believe I paid for this. It will not let me input any loads for the zones. When I try to input a load, it closes the app. Therefore the app is completely useless!!!!!!
With Family Sharing set up, up to six family members can use this app.
