Trucalc

TruCalc is a mobile-first HVAC load calculation and reporting tool built for Canadian contractors, designers, HVAC and energy professionals.
Create a project in minutes using quick inputs, plan tracing, or on-site scanning, then generate clear room-by-room heat loss and heat gain results that support CSA F280-style workflows.

Key features

• Room-by-room and whole-home heat loss and heat gain calculations (CSA F280 verified outputs)
• Weather and climate inputs using jobsite location (GPS while using the app) or manual entry
• Floor plan capture via on-site scanning or plan tracing to speed up takeoffs
• Inputs for envelope assemblies, windows, doors, air leakage/ventilation, and internal gains
• Clear reports for quoting, design review, and client sharing
• Save projects, revise inputs, and export reports on demand
• In-app purchases and subscriptions for report generation (managed through the App Store)

Designed for

• Residential HVAC contractors and designers
• All HVAC systems: heat pumps, furnaces, boilers, and dual fuel sizing

Workflows

• Retrofit and new construction estimating
Roadmap (coming soon)
• Equipment selection workflows, including air handler/heat pump pairing and dual fuel configurations
• HVAC energy modeling, including balance points and upgrade comparisons
• Duct sizing tools and airflow estimation to support distribution design

Important note

TruCalc is a decision-support tool and makes no guarantees. End users are responsible for verifying measurements and all other assumptions. Final equipment selection and design decisions should be verified against applicable codes, standards, and manufacturer requirements.

More modules are planned, including expanded equipment selection and HVAC modeling features.
