Expert Install thermostat in Sonoma County, CA

A thermostat installation from Custom Comfort Heating and Cooling gives Sonoma County homeowners direct control over their heating and cooling system. We install programmable and smart thermostats in homes across Santa Rosa, Petaluma, Sebastopol, and the surrounding area. Before any new thermostat goes in, we check your existing low-voltage wiring and confirm the unit is compatible with your HVAC system. Older Sonoma County homes sometimes have wiring setups that need attention before a smart thermostat will work correctly, so that check matters. We match the right thermostat to your system type, whether you have a standard furnace, a heat pump, or a multi-stage setup. If you are a PG&E customer, a qualifying smart thermostat installation may make you eligible for available utility rebate programs, so it is worth asking us about that when you call. Our goal is simple: give you a fair price and a system that works the way you expect it to.
