California Title 24 requires Home Energy Rating System (HERS) testing on qualifying AC installs — we handle the paperwork.

California Title 24 requires Home Energy Rating System (HERS) testing on qualifying AC installs — we handle the paperwork. For Placentia smart thermostat, that means the close-out packet has to line up with the permit, commissioning readings, warranty registration, and any rebate submission rather than stopping at a paid invoice.
Pacific Gas & Electric (PG&E) is checked because Heat pump rebates and zero-interest financing for qualifying energy-efficient equipment. If the Placentia job qualifies, the technician captures model numbers, AHRI matches where relevant, serial numbers, and customer approval so incentive paperwork does not become a separate scramble after installation.
One reason smart thermostat gets misquoted is that temperature reads inaccurately can look like a larger failure. Our Placentia diagnostic path starts with readings and conditions, then uses the finding to decide whether the fix is a part, adjustment, cleaning, control change, or replacement discussion.
The final Placentia note is intentionally plain: what failed, what measured out of range, what was corrected, and what remains optional. That makes the smart thermostat page match the actual field workflow instead of acting like a thin city doorway page.
The warranty record is attached to the Placentia job before close-out. If smart thermostat uses OEM material, model numbers and serial numbers are saved with the invoice; if the recommendation is maintenance or adjustment, the customer sees the readings that made replacement unnecessary.
Open the old thermostat, photograph the wiring, verify you have a C-wire (most smart thermostats need one). If not — we retrofit or add a 24V adapter.
