Your components, inside the engineer's design.
When an engineer sizes a system here, they pick real equipment from the catalog. If your compressor map or coil range is in it, every selection is your part in their specification, and every quote request a lead with the design attached.

Publish compressors (AHRI 540 maps), coils, fans and pumps with their curves, evaporative media, recovery cores, heaters and exchangers, with the markets you serve. Engineers select them directly in the builder; your name travels into their reports.
Selection analytics
See how often your items are solved with, simulated, saved and included in reports: which sizes get traction, and where.
Leads, not clicks
Quote requests arrive with the buyer's contact and the actual design context, in your portal and by email instantly, as one daily digest, or not at all, whichever you set. A lead from a solved system is half-qualified before you pick up the phone.

Onboard your whole range with AI
You don't have to type in datasheets. HVAC Builder speaks MCP: connect an AI assistant to hvacbuilder.app/api/mcp as a custom connector and sign in, or use an hvb_ API key for a script, point it at your selection-software exports or datasheets, and let it bulk-import your range with import_catalog_items. fit_compressor_map turns a published performance table into AHRI 540 coefficients first, with the fit quality reported per point. A full compressor lineup is a ten-minute session, validated item by item.
Already in the catalog? Claim it
Manufacturers' ranges are listed from their published data, Copeland's entire compressor database and Invotech's among them, and every such maker already has a company page here, unclaimed. If yours is one, register and claim the brand from the Company tab: the page and its listings become yours, quote requests for designs that use them reach you with the design attached, and any listing is yours to edit or withdraw.

How to start
Every published item gets a page
A published listing isn't only a row in the picker: it gets its own public page with the spec, your product photo, a link to your product site, and a quote form that works without an account, plus a slot in the public component directory and on your supplier profile.
List what you make where it is selected.
Three listings and twenty leads a month are free; the catalog already knows most makers by name.
