This app allows you to perform detailed block and room-by-room heating and cooling loads for residential buildings out in the field, by taking advantage of the simplicity and power of the iPhone.

This app was designed by Carmel Software Corporation, a 25-year old software design firm specializing in engineering analysis software applications. We are not just 1 person designing mobile apps out of a bedroom. We are a team of software developers and engineers with over 50 years combined software and engineering design experience. In fact, our software powers the analysis capabilities of major Autodesk (The makers of AutoCAD) software tools such as Autodesk Revit.

The following is just a small sample of the features included in this app:

1. Calculations based upon abridged ACCA Manual J8 calculations (This is not an ACCA-approved app. For our ACCA-approved iPad app, search for the HVAC ResLoad-J app on the app store)

2. Includes a 1000+ world-wide city weather database

3. Includes data for 100s of construction types for walls, roofs, floors, doors, windows, skylights, ceilings, and more

4. Allows you to create and store an unlimited number of projects

5. Allows you to create an unlimited number of rooms and view individual loads and airflows for those rooms

6. Allows you to specify an unlimited # of opaque types (ie – doors, walls, roofs, floors, ceilings), window types, and skylight types for each building

7. Allows you to instantly view total heating and cooling load results as you update input data

8. Allows you to view comprehensive cooling and heating load breakdown reports including breakdown by opaque load, window load, skylight load, infiltration load, ventilation load and internal load contributions

9. Opaque inputs include opaque type, opaque construction number, dimensions, and opening areas

10. Window inputs include window type, internal and external shading type, overhang dimensions, window area, and more..

11. Additional input types include # of people, # of bedrooms, ventilation airflow, and more..

12. Includes ability to display a wide variety of on-screen reports including checksum reports (ie – BTUh/SqFt, SqFt/Ton, etc.), complete heating and cooling load breakdown reports, and even graphically-pleasing pie charts showing cooling and heating load breakdowns

13. Includes the ability to display a comprehensive HTML report that you can email to yourself or others, and it also includes a spreadsheet attachment that you can open in Excel to further massage data on your desktop

14. Includes English (IP) or Metric (SI) units

15. This is the same technology that powers the Trane MAP iPad app that they offer to their elite dealer network

The benefits of using this app are numerous including:

1. Great for use out in the field. Quickly size heating and cooling equipment, show the client, then email the results back to your office for further analysis.

2. Show off your advanced on-screen reports to clients convincing them you are using cutting-edge technology

3. Save time by inputting information in the field and then returning to your office to perform more in-depth analysis

1. Fixed issues with screen scrolling all over the place on iOS versions 18.x and 26.x.
2. Added a Share button so you can now text, email, and download reports.
3. Updated help.
4. Optimized for iOS 26.
