Your home’s thermostat is the control point for your entire HVAC system. When your heating and cooling equipment is old, wrong, or not connected properly, it won’t work right. GoTech Air Conditioning & Heating provides professional thermostat installation and thermostat replacement for homeowners across Southern California. We can help you with a simple programmable thermostat or a modern smart thermostat. We take care of setup, wiring, and full system testing.
A faulty temperature control device can cause your system to run inefficiently or stop responding altogether. You may need a replacement if:
The temperature on the screen doesn’t match the room
Heating or cooling turns on at unusual times
The display is blank, faded, or slow
Your HVAC system short-cycles or never shuts off
You upgraded your furnace or AC and the old controller is incompatible
If you’re unsure what the problem is, we can diagnose the issue and recommend the best solution.
These are excellent for predictable routines. You can preset daily or weekly schedules to maintain comfort while reducing energy use during the day or night.
Wi-Fi–based controllers offer modern convenience and energy savings. Features include:
Smartphone app control
Voice assistant integration (Google, Alexa, Siri)
Learning algorithms that adjust automatically
Energy reports and usage insights
Eco and away modes
Multi-zone compatibility
Popular models we install include Google Nest, Ecobee, Honeywell Home, Sensi, and Emerson.
The cost of replacing or installing a new controller depends on the model and wiring requirements.
Typical installed pricing:
Programmable thermostat: $120–$250
Smart thermostat: $250–$500+
C-wire upgrades or rewiring: additional labor may apply
In many cases, the improved efficiency of a smart thermostat offsets the installation cost within one or two seasons.
