If properly sizing air conditioning units is critical to your business, this may be the most important tool you will ever use. Why waste hundreds of dollars on complicated heat load calculators that require extensive training and take hours to complete? With our Simplified Heat Load Calculator, you can run a block or room-by-room heat load in as little as 15 minutes from your iPhone or iPad. Your heatload data is organized by client, and each client can have multiple heat loads and zones. A pie chart outline offers easy evaluation of heat loss and heat gain problem areas. A room-by-room heat load will auto-calculate the appropriate duct size to run to each room. This free app will show you where improvements can be made in the building, and XactRate subscription members also receive exact BTU values for sizing air conditioning units.
