Who built this
Fast Estimate was built by Scott Herberg, who has spent 28 years in HVAC — most of it as a manufacturer's rep in the Pacific Northwest, working with the contractors this is built for. The estimate flow follows how a replacement job actually gets quoted in the driveway, not how software people think it works.
