ScanPlan: HVAC Load & Ducts

Now with AI Technical Docs, AC duct measurement. The complete HVAC field calculator. Test out a heatpump system build. Simulate energy efficiency and usage .

ScanPlan turns your iPhone or iPad Pro into a complete HVAC design toolkit. Scan rooms with LiDAR, calculate Manual J heating and cooling loads, size ducts and equipment, and generate professional PDF reports — all on-site.

LOAD CALCULATIONS • Manual J heating & cooling loads for every room and zone • Climate-aware psychrometrics: sensible heat ratio, enthalpy-based CFM • Infiltration, internal gains, slab, basement, and envelope losses • AI floor plan import — scan a photo or PDF to auto-detect rooms and dimensions

DUCT SIZING • Conventional duct sizing with multi-zone AHU grouping • Unico high-velocity system sizing • AR duct measurement — measure existing ductwork with augmented reality

HEAT PUMP SELECTION • Mitsubishi METUS equipment search — match indoor and outdoor units to your load • Ecodan air-to-water heat pump sizing with balance point calculator • Vitocal (Viessmann) monobloc sizing • Side-by-side heat pump comparison engine

DOMESTIC HOT WATER • DHW load sizing with occupancy-based peak demand • Heat pump water heater comparison with full energy cost analysis • Location-based cold-water temperature adjustment

GAS PIPING • LP and natural gas piping sizing (longest-length method, ACCA/AGA tables) • CSST, copper, and steel pipe sizing • Appliance-by-appliance results with warnings and failure flags

ENERGY & ECONOMICS • Whole-home annual energy cost analysis for heating and cooling • ROI and payback calculator versus existing equipment • Historical weather backfill using NOAA climate data • Live fuel price tracking: gas, propane, and electricity

AI-POWERED TOOLS • Photograph existing equipment — AI identifies specs and logs them to your project • AI Technical Assistant — search Mitsubishi Equiptment and METUS technical documents instantly. Expanding database of equipment install guides and technical documents. Use AI to provide answers that are specific to technical documents minimizing hallucination responses.

PROFESSIONAL OUTPUT • PDF reports for every tool: Manual J, duct sizing, equipment schedules, hydronics, Ecodan, Vitocal, Unico • 3D equipment placement on your floor plan • Project backup and multi-project export

Introductory Beta PRICING ScanPlan requires a one-time purchase for full access. A free trial lets you explore every feature before you buy — future subscriptions will be needed for AI features.
