Engineers first. Contractors second.
We built ThermoNex to do HVAC the engineering way — measure first, design precisely, install cleanly, and be honest about what a home actually needs.
Our Story
Why we started ThermoNex.
ThermoNex was founded by two energy engineers who spent their careers in energy compliance, sustainability, and building systems — and kept seeing the same problem: HVAC sold by salespeople and sized by guesswork.
Oversized equipment, missed rebates, systems that weren't designed for cold climates. Homeowners paying more than they should and getting less than they deserved. The engineering knowledge existed to do better — it just wasn't being applied at the residential level.
ThermoNex exists to fix that. Every recommendation we make is backed by load calculations and building science. We tell you what your home actually needs — even when it's the cheaper option.
