Frequently Asked Questions

Can I install a smart thermostat myself?

Some homeowners install basic smart thermostats themselves, but incorrect wiring is a common problem that can damage HVAC equipment. For heat pump systems, multi-stage systems, or if you’re unsure of your wiring, professional installation is recommended.

Will a smart thermostat save me money?

A properly programmed thermostat can reduce energy usage by avoiding unnecessary heating and cooling when the home is empty. Savings depend on how much your current schedule varies and how well your current thermostat performs.
