How to Figure Out if Your HVAC System Works with a Nest Smart Thermostat

March 10, 2021

If you’re among the typical American households who shell out more than $2,000 annually on heating and cooling expenses, getting a smart thermostat is a good approach to keep energy costs managed. Although most residences rely on programmable thermostats, chances are yours isn’t being made the most of because it’s on “hold” permanently.

When installing a new thermostat, the Nest smart thermostat is one of the most popular options. That’s because it picks up on your temperature preferences and schedule, and then develops an energy-efficient schedule to match. You can also monitor and lower 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 the thermostat pay for itself in less two years. And many utility businesses have rebate programs that help you get a smart thermostat for free or close to it.

When you’re getting a smart home thermostat, you’ll want to make sure it works with your HVAC system. This is especially essential if your equipment is getting old. If it’s not, you may have problems, like weird furnace or air conditioner behavior. That’s why it’s important to have a professional like Durable Service help you pick a new thermostat and handle your smart thermostat installation.

Here’s how to find out if the Nest can run with your HVAC system.

Nest Works with Most Heating and Cooling Systems

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

This includes heating and cooling systems that run on:

  • Natural gas
  • Oil
  • Electricity

Before you buy a Nest, you can run the Compatibility Checker to make sure you have a simple transition. Once you’ve double-checked it’s a fit, your Nest will work you through compatibility and wiring when you set it up.

The Nest Learning Thermostat is compatible with the widest types of home comfort units, such as heat pumps, furnaces and air conditioners. It also operates with highly energy-efficient multistage systems, dual-fuel equipment, humidifiers and dehumidifiers, but you’ll typically need a professional like Durable Service to do the complicated wiring and setup procedures.

Does the Nest Have to Have a C-Wire?

If you’ve looked into the Nest, you’ve potentially found details about the C-wire, or common wire. This wire powers your smart thermostat when it can’t get ample power from the other wires.

If you don’t have a C-wire, it’s probably still ok to install a Nest. The company says its thermostats were made to use not much power. In most cases, this means they can work normally without this wire.

Have a smart thermostat without a C-wire and noticing erratic heating and cooling behavior? An HVAC specialist like Durable Service can add a C-wire for you.
