I build tools that make hidden data legible. I'm the founder of CareCost Estimate, where I parsed tens of terabytes of federally mandated — but practically unreadable — healthcare pricing files into a tool anyone can use, and of Verified Supplement Data, which does the same for supplement labels and clinical evidence. Verified HVAC Data applies the same approach to home heating and cooling: read the primary sources most people never see — the AHRI certification registry, ENERGY STAR, EIA energy prices — and turn them into numbers you can check.
What I am, and what I'm not
I am not a licensed HVAC contractor or mechanical engineer, and nothing on this site substitutes for a proper load calculation and a professional install assessment. I'm a data engineer. That's exactly why every page here is built so you don't have to take my word for anything:
- Efficiency and capacity specs are sourced from the AHRI Directory and ENERGY STAR, cited by AHRI reference number
- Operating cost ($/MMBtu) is computed with a formula shown on the methodology page — not a hidden score
- Where a registry doesn't publish a spec, the page says "not published" instead of guessing
- When I get something wrong, email me and I'll fix it
HVAC sites usually hand you a star rating built from a formula they won't show you — or a lead form. I'd rather show you the source. The accountability here is the methodology and data you can check yourself.

Why I built this
HVAC buying online runs on two broken patterns: an undisclosed scoring formula standing in for numbers you could just check, and contractor-SEO pages that exist to sell your phone number. The AHRI registry is public. ENERGY STAR is public. Energy prices are public. Making all three legible and joining them to what a system actually costs to run is a data problem — and data problems are what I do.
