About This Product

First blueprint-to-calculation AI tool in the HVAC space. First calculation free, then $47/month for unlimited analyses. NOT ACCA-approved — follows Manual J methodology but cannot be used where ACCA-approved software is required by code. Independent HVAC engineer review notes it is useful for early-stage estimation but output is not defensible for professional liability. Emerging product with active development. Confidence medium given non-ACCA status and limited review depth.
