HVAC Logic
client-side HVAC & thermodynamic calculation suite
HVACLogic is an open-access, deterministic engineering calculation suite executing 100% client-side with full offline PWA support. It delivers 21 engineering tools for air duct sizing (Colebrook-White), Manual J heating/cooling loads, SEER2 AC tonnage, and A2L refrigerant diagnostics. Built with zero tracking cookies, transparent physics equations, and 1-click printable PDF job submittals.
Hi Product Hunt community! 👋
We built HVACLogic to solve a persistent issue in mechanical engineering and building science: most calculation tools on the web are either expensive desktop paywalls or ad-heavy sites that harvest customer project data.
HVACLogic is an open-access, deterministic suite that executes 100% client-side in standard JavaScript / WebAssembly:
⚡ Key Highlights:
1. 21 Engineering Tools: Sizing & diagnostics covering Colebrook-White duct hydraulics, ACCA Manual J heating/cooling loads, SEER2 AC tonnage, and A2L refrigerant saturation glide.
2. Complete Data Privacy: No user accounts, zero cookies, and zero project dimensions or equipment serials sent to any server.
3. Offline PWA Support: Works reliably in reinforced concrete mechanical rooms and basements without internet connectivity.
4. Transparent Physics: Every calculation exposes LaTeX governing formulas and worked numerical solutions.
5. Printable Job Cards: 1-click clean PDF submittals and CSV datasets.
We’d love to hear your feedback on the calculation performance, interface fluidity, and what engineering modules you’d like to see next!

Who hunted HVAC Logic?
HVAC Logic was hunted by miad. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
