How to Learn if Your HVAC System is Compatible with a Nest Smart Thermostat

March 10, 2021

If you’re among the usual American households who pay more than $2,000 each year on utility bills, adding a smart thermostat is a great way to keep utility costs under control. Although the majority of houses have programmable thermostats, chances are yours isn’t being used to the full advantage since it’s on “hold” every day.

When getting a new thermostat, the Nest smart thermostat is one of the most popular options. That’s due to the fact it adjusts to your temperature preferences and activities, and then develops an energy-efficient schedule to match. You can also keep an eye on it and raise it from nearly anywhere with your smartphone.

For the average home, Nest says its thermostat saves about 10-12% on heating costs and about 15% on cooling costs. That’s about $131 to $145 saved annually, which helps it pay for itself in less two years. And most utility providers have rebate programs that help you install a smart thermostat for free or close to it.

When you’re upgrading to a smart home thermostat, you’ll want to make sure it’s compatible with your HVAC system. This is especially true if your equipment is getting old. If it’s not, you may run into troubles, like weird furnace or air conditioner behavior. That’s why it’s critical to have a professional like Watts Electric & A/C Inc help you pick a new thermostat and do your smart thermostat installation.

Here’s how to figure out if the Nest is compatible with your HVAC system.

Nest Runs with the Majority of Heating and Cooling Systems

The good news is that Nest designed its thermostat to run with many different 24-volt systems, including aging ones.

This involves heating and cooling systems powered by:

  • Natural gas
  • Oil
  • Electricity

Before you buy a Nest, you can use the Compatibility Checker to make sure you have an easy transition. Once you’ve double-checked it’s a fit, your Nest will walk you through compatibility and wiring when you start using it.

The Nest Learning Thermostat can run with the biggest number of home comfort systems, like heat pumps, furnaces and air conditioners. It also works with highly energy-efficient multistage systems, dual-fuel equipment, humidifiers and dehumidifiers, but you’ll typically need a pro like Watts Electric & A/C Inc to handle the detailed wiring and setup steps.

Does the Nest Have to Have a C-Wire?

If you’ve looked into the Nest, you’ve probably run into info about the C-wire, or common wire. This wire runs your smart thermostat when it can’t get enough power from the other wires.

If you don’t have a C-wire, it’s usually still ok to get a Nest. The company says its thermostats were created to consume little power. In most cases, this means they can run correctly without this wire.

Have a smart thermostat without a C-wire and noticing weird heating and cooling behavior? An HVAC specialist like Watts Electric & A/C Inc can add a C-wire for you.
