About Tradewright
Engineered HVAC design, built for the people who sell it
From an address to an engineered HVAC design and a signed proposal, in one visit. We are building the tool we wanted: real engineering at the kitchen table, without slowing the sale down.

Where we're starting
New York and Massachusetts first
We are starting where the paperwork is heaviest. NYS Clean Heat and Mass Save both require Manual J documentation for heat pump incentives, so contractors there feel the cost of slow design work on every job.
From there we expand across the Northeast, the Mid-Atlantic and other cold-climate states, where heat pump sizing at design temperature matters most.
What we believe
Your salesperson gathers. Tradewright engineers. You decide how to sell.
Comfort advisors should not need design training to put a correct system in front of a homeowner. Engineering should not slow the sale down. And the contractor, not the software, owns the pricing and the relationship.
Deterministic, auditable engineering
The same inputs always produce the same loads and selections. Every input is visible and every number can be traced.
AI that explains, never invents
The AI explains every number in plain language. It never invents one. The math comes from the engineering engine, not a language model.
A neutral recommendation
The comparison ranks systems on fit and 15-year cost of ownership. It is never pushed toward a higher-margin product. You decide how to present and price the options.
Built on ACCA methods, stated honestly
Built on ACCA Manual J and Manual S methods. Tradewright is not yet on ACCA's approved software list, and we say so plainly.
