TruCalc Inc.

TruCalc is a Canadian-built HVAC load calculation app designed to help contractors quickly and accurately size equipment using CSA F280 standards. Our mobile-first platform allows users to scan or trace homes and generate professional heat loss and heat gain reports in minutes, eliminating guesswork and outdated rules of thumb. By improving sizing accuracy, TruCalc helps reduce callbacks, increase system performance, and build greater confidence with homeowners. Contractors can complete more calls per day while delivering higher-value, data-driven proposals that stand out in a competitive market. TruCalc is free to download (apple App Store & Google Play Store) with pay-as-you-go reporting, and we invite HRAI members to connect with us for a demo and see how it can transform your workflow.
