Can a Smart Thermostat Work with Any Furnace? A Simple Guide

With a smart thermostat, the sky’s the limit, and you can do everything from regulating the temperature of the furnace, setting the temperature for different parts of the house, and scheduling on and off times for the furnace. 

So, the answer is yes, a programmable thermostat will work with any type of furnace.

Making informed decisions when shopping can be a bit hard if you don’t have enough experience, which is why we’ve made up a list of things you want to look out for if you’re thinking about getting a thermostat that will work well together with your furnace.

What to Look Out For

Installation and Ease of Use

Installing and getting your thermostat running shouldn’t take multiple hours. The ideal thermostat will be straightforward to set up. 

The manual it comes with should also be easy to understand, and include all of the details you need to know in order to install it. You also need to know the exact places to put the common wire, which is the reason you must get color-coded thermostat wires.

Thermostat Compatibility

Compatibility is something that’s really important since it’s not a good experience to have to return items to the store when they aren’t compatible with your furnace. One of the first things you need to check when getting a smart thermostat is compatibility. 

To see if the furnace and the preferred smart thermostat are able to work together, first check the voltage of your furnace. Then check the voltage of the smart thermostat that you want to get.


What can truly bring your experience with the current thermostat to a whole other level is going for a smart thermostat that has lots of sensors. A smart thermostat works more efficiently if there are multiple sensors. 

Some sensors that you should definitely look out for are proximity sensors, motion sensors, and remote sensors. This can help your Wi-Fi thermostat in deciding when to turn off and on after usage.

Remote Access

The thing you should look out for when getting a thermostat that works with any furnace is to make sure that it can be controlled remotely, instead of a manual thermostat. A connected thermostat will be helpful not only for furnaces but for your whole home, so that you can set and control the temperature settings of the rooms at will.
