Executive Briefing
Client Background & Context
ClimateCool is a premier commercial and residential HVAC contractor servicing over 40,000 households. As the company scaled across three neighboring metropolitan regions, their legacy WordPress website and manual phone dispatch system became a severe operational bottleneck. Visitors faced slow loading screens, and prospective customers frequently abandoned booking forms before completion.
The Problem
The Friction: Slow Load Times & Inefficient Booking Flows
ClimateCool's digital portal was plagued with bloated plugins and unoptimized database queries, resulting in a mobile load time exceeding 4.8 seconds. When peak seasonal heat waves hit, server crashes cost them thousands in high-margin emergency service requests.
4.8s average mobile load time causing 58% bounce rate during peak demand
Manual telephone triage creating 45-minute dispatch backlogs for emergency calls
Disjointed customer records leading to duplicate entries and missed follow-ups
Inability to accept upfront diagnostic deposits securely online
