About this Gig

Need a complete residential HVAC design package for permit review, equipment replacement or new construction?

I will prepare the agreed Manual J, Manual S and Manual D documentation using your architectural plans, building-envelope specifications, project location and equipment data.

Available deliverables include:

  • Room-by-room heating and cooling loads
  • Orientation and solar-gain inputs
  • Wall, ceiling, floor and infiltration data
  • Manual S equipment-selection report
  • Sensible and latent capacity comparison
  • Required system airflow
  • Supply and return duct sizing
  • External static-pressure information
  • Register and grille airflow schedule
  • Duct layout when included
  • Organized permit PDF report


Accurate results depend on complete construction and equipment information. Changes to floor plans, insulation, glazing or equipment after calculation may require a paid revision.
