What to expect from our thermostat install service.
A modern smart thermostat can shave 10–15% off your heating and cooling bill, but only if it's wired and configured correctly. Most homes built before the 2010s don't have a C-wire (the common wire that powers a smart thermostat), and a self-install often leaves the thermostat browning out, dropping Wi-Fi, or burning out the control board on the furnace. Cranfield Services adds a C-wire when needed, configures multi-stage cooling and heating properly, sets up the right heat-pump or dual-fuel profile, and connects the unit to your Wi-Fi before we leave. We install Ecobee, Nest, Honeywell, Sensi, and other major brands, bring your own or have us recommend one.
Frequently asked questions.
Do I need a C-wire for a smart thermostat?+
Most smart thermostats require either a C-wire or a manufacturer-supplied power kit. If yours doesn't have one we'll add it during the install.
How long does a thermostat install take?+
Most jobs finish in 30–60 minutes including configuration and Wi-Fi setup. C-wire additions can stretch to 90 minutes.
Which smart thermostat should I buy?+
Ecobee and Nest are the most common premium picks; Honeywell T-series and Sensi are great mid-range options. We'll recommend based on your system type.
