Complete HVAC Design Package Contents

You can rest assured that your design needs will be met by HVAC Designs. Our designs are compliant with all relevant Air Conditioning Contractors of America (ACCA) design manuals and current Florida Building Codes.


Complete HVAC + ENERGY Design Package Includes:

  • Current Florida Energy Calculations (Residential, Commercial, and Public Buildings)
  • ACCA Adequate Exposure Diversity Calculations, prerequisite to Manual J 8th Edition V2.5
  • ACCA Manual J®, 8th Edition V2.5 Heat Load Calculations (Residential and Light Commercial)
  • ACCA Manual S®, HVAC Equipment Selection Procedure
  • ACCA Manual D®, Duct Pressure Loss Calculations
  • ACCA Manual T, Air Distribution Basics
  • ACCA Manual Zr®, Residential Duct Zoning Design
  • HVAC Intelligent Color CAD Drawings PDF format
  • HVAC Designs specifies heat pumps for residential, straight cool for commercial. No gas furnaces in Florida.

NOTE: HVAC Designs does not offer just heat load and energy calculations separate from a complete HVAC design because calculations based on partial effort are also based on several guesses. If you are currently using a “designer” or “service” that does not perform a complete design package as listed above, be aware their partial design effort, also known as “calc’s only”, will lack accuracy. Also know that these “calcs only” providers are at a much higher price for less than a complete design package! Many HVAC contractors and less than professional design services offer these expensive partial calculations that take just a few minutes to generate – but a complete accurate HVAC design package requires several hours of intelligent cad design to generate. Don’t leave your work to chance – demand a complete HVAC and energy design package that includes the code required HVAC ACCA “best practice” design Manual’s AED, J, S, ZR, T, and especially the ACCA Manual D scaled duct design. A complete HVAC design effort ensures your building is code compliant and comfortable.
