You should be certain that your HVAC is compatible before you try to hook up a smart thermostat. ![]() A good giveaway: you have one single thermostat in your house (or multiples if youre multi-zone) that controls a large furnace thats tucked away in your basement or garage (there might be additional accessories such as a heat pump, too). Likewise, there are lots of systems that are not compatible at all. For example, if you have a thermostat and heater pair in every room of your home, you probably have line voltage systems (which are not compatible with the popular smart thermostats available right now). For more help, check out our detailed guide (with lots of photos) for identifying your HVAC system type: Is your wiring compatible with a smart thermostat Guide to low voltage, line voltage, and more.

Its a good idea to determine if your wiring is compatible before you order a smart thermostat. You might have to look inside your furnace or in the wall behind your current thermostat to see if you do actually have enough wires and theyre just not in use and stuffed away, or you might have to order an adapter or new wire, or consider hiring a pro.

Your photos should be good enough to help you put your old thermostat back into service. Obviously, no one wants to think about having to put the old thermostat back on the wall, but if something goes awry during the smart thermostat installation youll be glad you can quickly undo and go back to what you had before. Also, if you end up having to call support theyll likely want to know how the old one was wired. Do your future self a favor and take some good, sharp photos of your existing wiring hookups before you take anything apart. Consider what will happen to the wall behind your existing thermostat In some homes, swapping thermostats is no big deal the wall is painted white and always has been, the old thermostat is small and your new one is bigger and so on. But in other homes, you might have to take on an additional wall repair project in addition to the thermostat replacement. The most common problems revealed when upgrading to a smart thermostat are wallpaper damage and mismatched paint that wont be fully covered by the new smart thermostat.

The wall plate that ships with Nest thermostats is easy to install just sandwich it between the wall and the thermostat to hide wall damage and mismatched paint that was previously hidden by your old thermostat. But if you dont want to use the wall plate, you might want to think (ahead of time) about whether you plan to repaint or repair the wall after youve put up the new smart thermostat.
