Walnut Scope and Scheduling Notes

Walnut is a mid-sized California market with about 27,250 residents, which usually makes scope clarity more important than comparing one advertised starting price. The place-area data works out to roughly 3,031 residents per square mile, so the estimate should still spell out access, arrival window, and work-area assumptions.

For HVAC, that means the HVAC service quote should separate diagnosis, equipment sizing, duct or airflow assumptions, permit work, warranty terms, and seasonal scheduling risk.
