About this Gig

Planning a new home, addition, renovation, or HVAC replacement? I can help you turn your plans into a clear, properly sized HVAC design.


I prepare accurate Manual J heating and cooling load calculations to determine how much heating and cooling your building actually needsnot more, not less. When your project requires a complete design, I can also provide Manual S equipment sizing, Manual D duct sizing, duct layouts, HVAC plans, and supporting permit documentation.


  • Manual J heating and cooling load calculations
  • HVAC system sizing and design support
  • Manual S equipment selection and sizing
  • Manual D duct sizing and duct design
  • HVAC permit plans and mechanical plans
  • HVAC drawings and equipment schedules
  • AutoCAD HVAC drawings
  • Revit MEP documentation
  • HAP or Wrightsoft-based calculations, where applicable
  • HVAC permit revisions and plan-review corrections


I work with residential new construction, additions, renovations, HVAC replacements, heat-pump projects, and other residential permit applications.
