Frequently asked questions
Does my system have the wiring for a smart thermostat?
Most do — and when a C-wire is missing we add one so the thermostat runs reliably without draining batteries.
Which smart thermostat is best?
It depends on your system and smart-home setup — we'll recommend the right Ecobee, Nest, or Honeywell and configure it.
Can it work with my smart home?
Yes — we tie it into your existing smart-home platform for voice and automation control.
