What to expect
Thermostat installation and zoning controls cover smart thermostats (Nest, Ecobee, Honeywell T-series), zone dampers, and communicating system controllers. Many smart thermostats need a C-wire — check before purchase to avoid an unexpected install charge.
California's cooling needs span 800 CDD (coast) to 3,500+ CDD (Central Valley desert). The Title 24 energy code drives high-efficiency installs statewide.

Frequently asked questions
Do smart thermostats really save money?
Most studies show 8-15% on heating, 10-20% on cooling for households that previously didn't program a thermostat. The savings come from setbacks during unoccupied periods, not the device itself.
What is a C-wire and why does it matter?
A common wire provides continuous low-voltage power for the thermostat's display and Wi-Fi. Older homes often lack one. Options: add a C-wire ($100-$200), use a C-wire adapter, or pick a battery-only smart thermostat.
Can one thermostat control upstairs and downstairs separately?
Only with a zoned system — separate dampers and controllers per zone, all wired to a zone panel. Retrofitting costs $2,000-$5,000 per added zone.
