Nest vs ecobee vs Honeywell: A Twin Cities Integrator's Honest Take (and the C-Wire Problem)

August 14, 2026 · HVAC Control

Which smart thermostat to buy, why the missing C-wire in older Plymouth and Minnetonka homes stops installs cold, and how to run climate from one app.

# Nest vs ecobee vs Honeywell: A Twin Cities Integrator's Honest Take (and the C-Wire Problem) You're comparing three thermostats, but the decision that actually derails installs in this market isn't the brand. It's a single wire behind your wall. In the 1980s split-levels around Plymouth and the 1970s ramblers near Hopkins in Minnetonka, the thermostat was wired with four conductors and no C-wire, because a mercury-bulb thermostat never needed constant power. Every modern smart thermostat does. We install these into Control4 and Savant systems across the west metro every week, and the pattern is consistent: the brand debate takes five minutes, and the wiring behind the plate is what decides how the day actually goes. Here's the honest version of both. One scope note first, because it matters. We're a low-voltage integrator, not an HVAC mechanical contractor. We don't touch your furnace, your ductwork, or refrigerant. What we do is the thermostat, the low-voltage wiring behind it, and folding climate into the same app that runs your lighting, audio, and shades. If the fix is a furnace board or a dead blower, that's your HVAC company's call, and we'll tell you so. ## Nest vs ecobee vs Honeywell: How We'd Choose All three are excellent thermostats, and none is a wrong answer for a Twin Cities home. The split is about what each one does best. **ecobee's edge is the remote room sensor**, so the thermostat averages temperature across the rooms you actually live in instead of o
