This app may just change the way you do business!

This is the FIRST comprehensive mobile HVAC block load calculation software app available today. It allows you to perform detailed heating and cooling loads for small commercial and residential buildings out in the field, by taking advantage of the simplicity and power of the iPhone, iPod touch, or iPad.

This app was designed by Carmel Software Corporation, a 15-year old software design firm specializing in engineering analysis software applications geared toward engineers, architects, technicians, and home owners. In fact, our software powers the analysis capabilities of major Autodesk software tools such as Revit (The makers of AutoCAD).



The “HVAC Load Plus” app performs heating and cooling block load calculations based upon industry standard calculation methods. The following is just a small sample of the features included in this app (including screenshots):
  1. Includes a 1000+ world-wide city weather database


  2. Allows you to create and store an unlimited number of projects. You can also copy existing projects to new projects for easy reuse of data



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


  4. Allows you to specify an unlimited # of opaque types (ie – doors, walls, roofs, floors, ceilings), window types, and skylight types for each building
  5. Allows you to instantly view total heating and cooling load results as you update input data


  6. 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


  7. Opaque inputs include opaque type, opaque construction number, dimensions, and opening areas
  8. Window inputs include window type, internal and external shading type, overhang dimensions, window area, and more..
  9. Skylight inputs include skylight type, dimensions, orientation, and more..




  10. 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










  11. 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


  12. Includes ability to display units in either English (IP) or Metric (SI).

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
As a bonus, our “Quick Load” app is also included with this app. The HVAC Quick Load allows you to quickly perform rule-of-thumb heating and cooling load calcs based upon just inputting the building type, square area, and # of people. Please see the description located under the stand-alone "HVAC Quick Load" app for more details about it.
We also offer for sale the HVAC Res Loads app. The difference between this HVAC Load Plus app and the HVAC Res Loads app are:
  1. The HVAC Load Plus app includes the HVAC Quick Load app functionality
  2. The HVAC Res Loads app allows you to perform room-by-room load and airflow analysis
  3. The HVAC Res Loads app includes a more comprehensive building materials database for walls, roofs, floors, ceilings, windows, and skylights
  4. The HVAC Res Loads app includes a more detailed HTML report
