Pinch or Ctrl/Cmd-scroll to zoom into any sheet. The first 3 sheets are free to preview above — the remaining 14 sheets unlock with a one-time $4.99 purchase.
Unlock all 17 sheets: full Manual J/Manual S load calculations, heat pump balance point sizing, floor/attic/roof plans, installation details, and control/wiring diagrams. Instant access after purchase — yours to keep, no expiration.
Or skip picking — the All-Access Pass unlocks every Professional Program, exam, and premium guide on the site, including anything added later, for one flat price.
A full permit-ready HVAC design package for a 2,500 sq ft single-zone residence in a mixed-humid climate: the cover sheet with project data, vicinity map and sheet index; general notes, abbreviations, symbols and legend; HVAC equipment and diffuser schedules; a complete ACCA Manual J load calculation (summary, rooms & zones, and component-level detail); ACCA Manual S equipment selection; heat pump balance point and electric backup heat sizing; the HVAC floor plan and attic mechanical plan showing supply/return duct routing; the roof plan with vent and penetration locations; typical HVAC installation details, equipment mounting details, duct penetration and sealing details, and condensate drain details; and the HVAC control diagram and wiring diagram.
Scroll or use the Prev/Next buttons at the bottom to move between sheets, or press the arrow keys. Click the ☰ menu button in the top-right to open the full sheet index and jump directly to any sheet. To zoom in on a detail — a schedule, a dimension string, a wiring callout — hold Ctrl (or Cmd on Mac) and scroll, pinch on a trackpad or touchscreen, or use the +/− buttons in the bottom-right corner of the sheet; drag to pan while zoomed in, and double-click or use the reset button to return to the full-sheet view.
HVAC designers and engineers studying how a complete Manual J/Manual S-backed residential HVAC package is actually assembled and organized, contractors and estimators who want to see a full real drawing set before bidding similar work, and NATE or PE Mechanical exam candidates who benefit from seeing load-calculation methodology applied to a real floor plan rather than an isolated textbook example.
It is a complete, realistic single-family residence HVAC design package built to the same structure and content a licensed HVAC designer would produce for permitting — cover sheet, ACCA Manual J/Manual S calculations, floor/attic/roof plans, installation details, and control wiring — not a simplified textbook illustration.
Yes. Every sheet is a high-resolution image and the reader supports pinch-zoom, Ctrl/Cmd-scroll zoom, and click-drag panning, so you can zoom into any schedule, dimension string, or detail callout for a clear, legible view.
The first 3 sheets — the cover sheet, general notes/legend, and HVAC schedules — are free with no purchase or account required. The remaining 14 sheets unlock with a one-time $4.99 purchase.
No. Checkout is guest-only via Stripe — no account required. After purchase you get a bookmarkable access link, and you can always recover it later with the restore-by-email link using the email you checked out with.
This is an in-browser interactive reader, not a file download — it is designed for studying and referencing the drawing set directly in your browser with full zoom/pan detail, similar to the site's other interactive readers and illustrated guides.
Disclaimer: This drawing set is an educational reference example illustrating a typical residential HVAC design package and its ACCA Manual J/Manual S methodology. It is not a construction document for any real project, has not been engineer-stamped for a specific jurisdiction, and should not be used for actual permitting or construction without independent review by a licensed HVAC designer or engineer. Always verify design conditions, code requirements, and equipment sizing against the applicable local codes and the Authority Having Jurisdiction.
