Your thermostat is the brain of your HVAC system. When it fails or falls behind, the whole system runs less efficiently, even when the AC and furnace are fine.
An old or failing thermostat wastes energy and leaves rooms uncomfortable. Replacing it is quick, affordable, and one of the best-value HVAC upgrades you can make.
Here are the signs Los Angeles homeowners should watch for:
Los Angeles homes run their AC through a long cooling season, so a smart thermostat that schedules around the heat pays for itself quickly. Many smart models also qualify for LADWP or SoCal Edison rebates.
We install and set up every major type of thermostat, and we help you choose the right one for your system and budget.
Smart thermostats - Wi-Fi models like Google Nest and ecobee learn your schedule, adjust the temperature automatically, and let you control your home from your phone.
Programmable thermostats - Follow a daily schedule you set once. A reliable, lower-cost upgrade from an old manual dial.
Heat pump thermostats - Heat pumps need a thermostat that controls auxiliary and emergency heat. We install models matched to your heat pump.
C-wire and power - Many older LA homes have no common (C) wire. We add one or install an adapter so a smart thermostat gets steady power and does not drop offline.
Smart-home integration - We connect your thermostat to Alexa, Google Home, or Apple Home and confirm scheduling and geofencing work before we leave.
We do more than swap a faceplate. We make sure the new thermostat is compatible, wired correctly, and fully set up.
Compatibility check - We confirm your system type, your wiring, and whether you have a C-wire, then recommend the right thermostat for your setup.
Wiring and mounting - We safely cut power, label every wire, mount the new thermostat level on the wall, and add a C-wire or adapter when one is needed.
Setup and testing - We program your schedule, connect Wi-Fi and the app, and test both heating and cooling so everything works before we leave.
We are not tied to one brand. We install what fits your system and your goals, and we tell you what we would put in our own home.
Google Nest - Learning thermostats with a clean, simple interface and strong energy-saving features. A great fit for most LA homes.
ecobee - Smart thermostats with remote room sensors that even out temperatures between rooms. Great for two-story homes.
Honeywell Home - Reliable smart and programmable models, including options built for older systems and trickier wiring.
Heat pump and basic models - For heat pumps or simple budget upgrades, we install matched or straightforward programmable thermostats that just work.
Thermostat installation is one of the most affordable HVAC upgrades. The price depends mostly on the thermostat you choose and your existing wiring.
Most thermostat installations in Los Angeles run $180 to $350. A basic programmable thermostat is the low end. A smart thermostat like a Nest or ecobee, especially when we need to add a C-wire, is the higher end.
The thermostat itself is the biggest variable. Basic programmable models cost around $40 to $80. Smart thermostats run $130 to $300 depending on features and included sensors.
If your home has no common (C) wire, which is common in older LA houses, we add one or install an adapter so a smart thermostat gets steady power. That adds a little labor but prevents the dropouts people often get from DIY installs.
Our $99 service call is waived when you approve the installation, so the diagnostic does not stack on top of the job.
You get a firm flat price before any work starts. No surprises, and no pressure to buy the most expensive model.
Many smart thermostats also qualify for utility rebates from LADWP or SoCal Edison, which lowers your net cost. We will point you to the current programs.
Add it up and a professional thermostat installation is a small investment that improves comfort, lowers your bills, and protects your HVAC system from wiring mistakes.
