01Features

Built for the way HVAC catalogs actually work.

Generic chatbots hallucinate model numbers. SignalHVAC is grounded in your catalog and trained on the structure of HVAC documentation — voltages, BTUs, refrigerants, line set lengths, and the fine print that decides a sale.

Catalog-aware answers

Every reply is grounded in your own SKUs, spec sheets, and install manuals — with the source cited inline.

Cross-brand compatibility

Match indoor and outdoor units, line set sizing, voltage, and refrigerant across brands without leaving the chat.

PDFs, sheets, and tribal knowledge

Drop in datasheets, distributor price lists, and the notes living in your reps’ heads. SignalHVAC reads them all.

Two-line embed

Paste a script tag and the widget appears on any product page — pre-scoped to that SKU, no setup per page.

Says “I don’t know”

When the catalog doesn’t cover it, you get an explicit hand-off instead of a fabricated spec.

Real-time inventory

Connect your ERP and the assistant quotes stock, lead times, and alternate SKUs alongside the spec answer.

02How it works

Three steps to a catalog that talks back.

STEP 01

Connect your catalog

Point SignalHVAC at your product feed, drop in PDF datasheets, or sync your ERP. Most distributors are live in under an hour.

STEP 02

Train on your docs

Install manuals, warranty rules, regional code notes — anything text or PDF. Re-indexing is automatic on catalog changes.

STEP 03

Deploy two ways

Send a link for the standalone chat, or paste two lines of HTML to embed the widget on any product or support page.

03Embeddable widget

Live on every product page, scoped to the SKU.

Drop the widget into any catalog page and it inherits the SKU context automatically. Buyers ask "will this fit a 1,800 sq ft single-story?" and get an answer tied to that exact unit — no model number lookups. Scope it to your brand, a specific series/model, or the full public catalog.

SignalHVAC · CH-S-12K

Will the Sophia 12k cool a 1,800 sq ft single-story?

For 1,800 sq ft you'd typically need ~24–30k BTU. The 12k covers around 550 sq ft. Want me to suggest a multi-zone setup?
