Digiduct vs ScanPlan

The Digiduct app is a powerful tool designed for HVAC professionals, supporting everything from design calculations to real-time field verification. Built utilizing the equations and recommendations from the ASHRAE Fundamentals – Duct Design chapter, it ensures your calculations are accurate and reliable, saving you time and reducing errors. Key Features: • Multiple Shape Sizing Options: Supports sizing for rectangular, round, and flat oval ducts, offering flexibility for various duct designs. • Customizable Dimensions: For rectangular and oval ducts, users can lock in one dimension, and the app calculates the other, ensuring precise results based on CFM, pressure drop due to friction, or velocity. • Duct Location Intelligence: offers the user predefined parameters to use as starting point and reference when selecting duct sizes so users at HVAC experience level can make confident selections. Why Choose Digiduct? Unlike other duct sizing tools, Digiduct goes above and beyond. It doesn’t just provide basic size outputs—it evaluates the location and context of your duct (high-pressure vs. low-pressure, shaft vs. plenum), alerting you if your selection exceeds maximum pressure drop or velocity limits. This added layer of intelligence ensures higher accuracy and gives users confidence that their sizing is optimal for the application. Get the assurance of precision with Digiduct—designed to meet the demands of real-world HVAC scenarios.

ScanPlan HVAC — LiDAR Scanning, Manual J Loads, and Equipment Sizing for HVAC Pros ScanPlan HVAC turns an iPhone or iPad LiDAR scan into a complete residential HVAC design package — room geometry, heating and cooling loads, equipment sizing, energy analysis, and a shareable client report, all in one app. Built for HVAC contractors, energy auditors, and sales reps, with a simplified mode for homeowners exploring a heat pump upgrade. Scan, Don't Measure • Walk through a home with LiDAR and capture room dimensions, walls, windows, and doors in 3D — no tape measure required. • Automatically detect and split rooms from a single scan, or place windows, doors, and skylights manually on a 2D floor plan. • Start a project instead from an existing floor plan or heat-loss report — AI reads the PDF or photo and builds your rooms automatically. • Organize multi-story homes by floor level, each with its own ceiling and foundation defaults. Accurate Load Calculations • Room-by-room and whole-building heating and cooling loads, powered by the Ross Energy Performance Model. • Design conditions pulled automatically from local weather data for your project's exact address, with IECC climate zone shown separately as a clear fallback estimate. • Blower-door test (CFM50) or natural infiltration modeling, humidity and latent load tracking, and dehumidifier sizing. Size the Right Equipment • Heat pumps: Mitsubishi M-Series and Ecodan air-to-water, Viessmann Vitocal monobloc, Gradient window units, and GeoStar geothermal — sized against your actual loads and manufacturer performance curves, not generic estimates. • Domestic hot water systems, hydronic panel radiators, condensing boilers with outdoor reset, gas piping (natural gas and propane, longest-length method), and residential duct sizing with AR duct measurement. • Track existing installed equipment — scan a nameplate with the camera and let AI log the model and specs. Know the Energy Impact • Building Energy Intelligence models multi-year energy use and cost from real historical weather, with a Comfort Performance dashboard scoring humidity and temperature control room by room. • Compare existing equipment against proposed upgrades: operating cost, ROI and payback period, and side-by-side efficiency ratings. • Energy Savings Lab lets you test what-if upgrades — insulation, air sealing, new equipment — in a sandbox that never changes your saved project. Rebates and Financing • Find federal, state, and utility heat-pump rebates and financing options for the project's address, and auto-fill state rebate claim forms. • Generate polished, shareable PDF reports for every analysis — load calculations, equipment selection, energy savings, and more. • Export and share full projects — including 3D scans — with clients or other ScanPlan users. AI Assistance, Built In ScanPlan AI answers technical questions from manufacturer documentation, reads equipment nameplates and spec sheets, imports floor plans and heat-loss reports, and helps classify existing equipment — all from within your project. **AI-Powered Manual J® Report Import** Import existing Manual J reports using AI to extract heating and cooling load data for use within ScanPlanHVAC. ScanPlanHVAC is not ACCA-approved Manual J calculation software. Whether you're a contractor sizing a replacement system, an auditor documenting a retrofit, or a homeowner deciding on a heat pump, ScanPlan HVAC replaces guesswork and rules-of-thumb with real building data.
