The building shell here is a fixed stand-in, not a survey of your house, and the DXF and gbXML exports carry geometry only — no equipment capacities, brands, refrigerants or electrical data.
The calculation engine has not yet been checked against a reference tool on a real house. Treat every number here as a starting point to verify, not a finished answer.
Check the results before you act on them. Verify against the equipment data plate, the manufacturer's installation manual, and your own measurements. You are responsible for what you install — Cheek Heating & Cooling LLC is not liable for decisions made from this tool's output.
Before you use this view
This 3D view produces design-assist estimates, not engineered drawings. The building shell is a fixed 30 by 40 ft stand-in and the routing paths are typical assumptions, not a survey of this home. Field-verify everything before installation.
Implements the ACCA Manual J 8 Abridged Edition calculation method — not part of any ACCA software-approval program. Not for permit or engineering submission unless reviewed and sealed by a licensed Professional Engineer.
3D system view
A walk-around view of the system you are proposing — equipment drawn from real catalog cabinet dimensions, with the lineset, vent, condensate and power runs where they would actually go. Change the furnace and watch the vent change with it: an 80% furnace vents in metal, straight up through the roof; a 90%+ condensing furnace vents in sealed PVC, intake and exhaust, out a sidewall.
Illustration only — a representative layout to show a homeowner where equipment and lines would go. Not an engineered mechanical drawing, not an as-built, and not a survey of this home. Confirm sizing, routing, clearances and terminations against the manufacturer's install manual and your local code.

Legend
Small-diameter lines are drawn slightly oversize so they read at house scale. Pipe sizes shown in the inspector are the real nominal sizes.
Download
Take this design to CAD or to an engineer's analysis tools. Both files say what they are: design-assist documents, not stamped drawings.
The DXF is a 2D plan of the equipment and routed runs on National CAD Standard layers. The gbXML carries the equipment, capacities and design loads for an engineer's model — no building-shell geometry, and the file says so.
