About this Gig

Poorly sized ductwork and mismatched equipment are the #1 reason HVAC systems underperform uneven temps, high bills, and callbacks.


I provide complete HVAC engineering including duct sizing (Manual D), equipment selection (Manual S), and system layout design that keeps airflow balanced and equipment running efficiently. Every design is based on accurate load calculations and follows ACCA/ASHRAE standards.


What you get:

  • Manual D duct sizing and layout
  • Manual S equipment selection matched to your load
  • Airflow (CFM) calculations per room
  • Duct material and sizing recommendations
  • Equipment specification sheet
  • Code-compliant PDF report ready for installers/permitting


Ideal for contractors, installers, builders, and homeowners who need a properly engineered system instead of a rule-of-thumb estimate. Correct duct sizing means better airflow, lower costs, and equipment that lasts.


Send your load calculation (or request one as an add-on) with your plans, and I'll deliver a design ready for installation or permitting.


Message me first if your project needs custom or commercial scope.
