Hey Product Hunt community! 👋 As a software engineer, I’ve always believed that technology should solve real-world complexities with absolute precision. The idea for HomeCalc Pro came from seeing homeowners, first-time buyers, and contractors lose thousands of dollars on home projects due to rough estimates, outdated spreadsheets, or contractor rules-of-thumb. An oversized HVAC system can waste $400–$800 per year in energy costs, while under-ordering concrete can cost hundreds in short-load fees—all completely preventable errors. To eliminate this guesswork, I built HomeCalc Pro—a platform featuring 100+ precision calculators engineered to the exact standards contractors and engineers rely on: Verified Accuracy: Sourced directly from ACCA Manual J standards, IRC building codes, and manufacturer specs. Privacy-First: Every single calculation runs 100% locally in your browser—zero data stored, no accounts required, and no tracking. Comprehensive: Covers everything from HVAC load sizing and material estimation to mortgage analysis and utility savings. I’d love to hear your feedback, feature requests, or any ideas on calculators you’d like to see added next. Thanks for checking it out! 🚀
