Problem

HVAC contractors miss 30%+ of inbound calls but treat it as background noise. They need a concrete dollar figure to take it seriously.

What I built

A simple input-driven calculator (avg ticket, call volume, miss rate, close rate) that outputs monthly + annual lost revenue. Embedded on landing pages as a lead magnet with email capture.

Outcome / purpose

Used as the top-of-funnel hook for an HVAC marketing offer — converts cold visitors into booked discovery calls by making the problem feel real in under 30 seconds.
