HVAC load calculations
Guessing Your HVAC Size is Costing You Money. An air conditioner that’s too large will short cycle, wasting energy and failing to control humidity. One that’s too small will run constantly, straining to meet demand. Our professional Manual J load calculation is the industry-standard, data-driven method to determine the exact heating and cooling capacity your home requires—no more, no less.
01.
Comprehensive Manual J Calculation
- Climate Data: Precise local weather data for South Florida.
- Building Materials: Insulation R-values, window types (U-factor/SHGC), door types, and wall construction.
- Orientation & Shading: Solar heat gain based on window direction and external shading.
- Occupancy & Usage: Number of occupants, appliance loads, and desired indoor conditions.
- Air Infiltration: Estimated based on construction quality and sealing.

Manual D Duct Design Calculations
A perfectly sized unit needs properly sized ducts. Using the results from Manual J, we perform a Manual D calculation to design a ductwork system that delivers the correct amount of conditioned air (CFM) to each room quietly and efficiently.
03.
Equipment Selection (Manual S)
We use Manual S to select HVAC equipment whose capacities match the calculated loads. This ensures the selected system can meet demand at both design conditions and part-load operation for optimal efficiency.
