Thermostat installation, San Jose

The right thermostat for the system you actually have

A thermostat is the part you touch every day; it should match the system behind it.

Thermostats

Replace, repair or match

A blank screen, a system that ignores the setting, or a new heat pump that needs a control that understands it. We wire it right and set it up for your equipment.

Heat pumps need a thermostat that knows about the reversing valve and backup heat. Put the wrong one on and the system works against itself.

What you can do, and what we do

  1. Yours to set

    You: batteries, schedules, the app, the temperature you like.

  2. Ours to wire

    Us: new wiring, a missing common wire, a heat pump or a multi stage system, and anything where the wrong wire can damage the equipment.
