We don’t offer just heat load and energy calculations separate 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 – we refer to these partial design packages as “FAKE” design packages.  Our current building codes require a complete design package – you may also notice that these fake “calc’s only” provided by others are at a much higher price! Many HVAC contractors and less than professional design services offer partial design packages that take just a few minutes to generate – but a complete design package requires several hours of intelligent cad design (per HVAC system) to generate.  Don’t leave your work to chance – demand a complete HVAC and energy design package that includes the code required hvac design Manual’s J,S,ZR,T, and especially the Manual D scaled duct design to ensure your building is both code compliant and comfortable.


All HVAC + Energy design packages are COMPLETE and Florida code compliant.
