Ecobee and Nest installs
C-wire, heat-pump config, and not frying the board.
We install them. We also fix the ones that were configured as the wrong system type.
Blank thermostats, wrong mode, and dead C-wires create “no heat” calls that are not furnace failures.
Use this as a field guide to Nest thermostat installation, then book a visit if the house still misbehaves.
We verify power, mode, and whether a communicating control is actually talking to the board before we open the gas valve.
We map Nest thermostat installation to the actual failed part or design limit. Age of the system is a data point, not the diagnosis.
You approve any repair after the findings are written down. Diagnostic visits are a flat $69. New installation estimates are free in-home with a load calculation — not a number invented from square footage on Zillow.
A Nest on a heat pump set to “gas furnace” will look like the outdoor unit is broken.
A company that skips testing on Nest thermostat installation will skip it on the next call too. We would rather lose a job than install the wrong thing.

Frequently asked questions
What do you test on a Nest thermostat installation visit?
We verify power, mode, and whether a communicating control is actually talking to the board before we open the gas valve. The visit is a flat $69. Repair work starts only after you approve the written findings.
Will you quote Nest thermostat installation from a photo?
No. We do not price Nest thermostat installation from a driveway photo. $69 diagnostic, then a quote — or a free in-home install estimate if replacement is the honest path.

Yes. We run Pleasant Hill, Clayton, and the rest of our East Bay list from 2939 Santos Ln, Walnut Creek. Hours are 7am–5pm every day — not 24/7. Call (650) 900-0440.
