HVAC Tools Hub | HVAC Calculators & Engineering Tools
Practical HVAC calculators, engineering tools, guides, comparisons, and technical references.
StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 3 August 2026; the live site may have changed since.
HVAC Tools Hub | HVAC Calculators & Engineering Tools covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
The site is hosted on GitHub Pages and served through Fastly, with a domain registered 2 weeks before launch. Our crawler found 11 technologies on this site, covering directory, analytics, CDN, and DNS providers. The stack includes Cloudflare DNS, Fastly, and Findly.tools.
It's also running the same core stack as 2,077 other launches.
