Hey Product Hunt! 👋 I built HVAC Admin because I kept hearing the same complaint from HVAC technicians: "I don't need another subscription app — I just need quick tools that work on my phone at the job site." So here's what we made: 🔧 Free calculators — BTU load, superheat/subcooling, duct sizing — no signup, instant results. 📄 Invoice generator — Create and PDF-export professional invoices in under 2 minutes. 📚 Knowledge hub — Refrigerant pressure charts, capacitor cross-reference, and troubleshooting guides all in one place. Everything runs in the browser, works offline-ish (PWA), and is 100% free. No ads, no paywall. Would love to hear what other tools HVAC pros (or anyone in the trades) wish they had! 🛠️
