A smart thermostat only pays off if it's wired correctly for your HVAC type — especially heat pumps and dual-fuel. We handle wiring, calibration, and setup so you actually get the savings it promises.
Irvine is home to roughly 266,122 residents across CA. We serve Woodbridge, Northpark, and Turtle Rock, plus surrounding neighborhoods for smart thermostat. California Title 24 requires Home Energy Rating System (HERS) testing on qualifying AC installs — we handle the paperwork. Ask about current rebate programs from Southern California Edison (SCE), SoCalGas that can offset qualifying smart thermostat work.
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.
Install ecobee, Nest, Honeywell, or Emerson. Wire O/B for heat-pump reversing valve; wire W2 for auxiliary-heat staging. Configure schedules + sensors.
Sync with your HVAC, test heat/cool/fan cycles, walk you through the app. 1-year install warranty.
Usually weak 2.4GHz coverage at the thermostat location. Mesh extender or relocation fixes it.
O/B reversal is the #1 install error. We verify heat-call vs cool-call behavior during commissioning.
Compatibility issue between thermostat + heat-pump brand. We reconfigure staging or swap to a brand-specific model.
Adapter (ecobee PEK or Nest Power Connector) for most setups; full C-wire retrofit for tougher cases. $120-$180 either way.
Thermostat placed in sunlight, near a vent, or on an exterior wall. We relocate + recalibrate.
“We'd been living with this smart thermostat problem for weeks. They caught the root cause a previous company missed. Runs quieter now than when it was new.”
“Same-day smart thermostat in Irvine. Showed up when they said, diagnosed in under 30 minutes, had the part on the truck. No surprises on the invoice.”
“Our smart thermostat quote was in writing before anyone touched the system. The tech showed pressures, temperatures, and the failed component. Honest work.”
Yes — typical CA homes save 8-15% on heating/cooling costs with proper setup. Most of the savings come from accurate schedules, not the AI — so calibration matters more than brand.
Most smart thermostats do. If yours doesn't have one, we can retrofit or add a 24V power adapter. Typical C-wire add runs $120-$180.
Yes — heat-pump thermostats need correct O/B wire configuration and auxiliary-heat setup. We do this weekly in Irvine.
Usual culprits: low refrigerant charge (efficiency drops 10-30%), dirty filter/coil, a stuck reversing valve on a heat pump, or failing capacitor causing compressor short-cycling. {company} checks all four on the first diagnostic visit.
As a rule of thumb, if repair costs exceed 50% of a new unit's price, or your system is over 10 years old and needs a major repair, replacement is usually the better investment. {company}'s technicians will give you an honest assessment.
14.3 SEER2 (the 2023 federal minimum) saves vs. a 10+ year old unit. Going to 17 SEER2 pays back in 6-8 years on Irvine's cooling hours. Above 20 SEER2 only pays back if you stay in the home 12+ years.
