Coldwave booked 23% more installs during a 115° Phoenix summer.

Phoenix summers don't politely wait their turn.

Coldwave HVAC is six trucks running fourteen-hour days from May to October. Phoenix can hit 115° and stay there. AC failures aren't inconveniences — they're medical risks for elderly customers. The phone rings two hundred times a day, and most of those calls are urgent service.

The cost: install consult inquiries — the high-margin work — were getting buried. By the time someone called back the homeowner shopping a new system, three competitors had already given quotes. Derek calculated they were losing roughly $180,000 a year in install work just to slow lead response.

Taiso took every install consult call within 60 seconds.

Coldwave layered Taiso on top of their existing ServiceTitan setup. Service emergencies still go to dispatch — that part didn't change. But install consults — "I want to replace my old system" — Taiso owns end-to-end. It collects square footage, system age, brand, age of ductwork, budget range, and homeowner timeline, then books an in-home estimate.

The estimator shows up to a fully briefed appointment. Customer feels heard. Quote-to-close rate went up alongside the booking rate.

What Taiso does for Coldwave specifically:

• Collects pre-consult data — sq ft, system age, brand, ductwork condition, budget
• Books in-home install estimates and routes them to the right estimator
• Sends customers a pre-visit checklist (gate codes, pets, attic access)
• Routes urgent service calls to dispatch with full symptom triage
• Knows the service area and never books outside it

The compounding effect.

Faster lead response did more than book more installs — it changed which leads Coldwave won. Homeowners told Marco "you guys called me back fastest" three times more often after Taiso went live. The lead-to-close rate went from 28% to 41% in a single quarter. Same leads. Different first impression.
