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

March 10, 2021

If you’re among the average American households who spends more than $2,000 each year on utility bills, adding a smart thermostat is a good way to keep energy costs under control. Although most houses rely on programmable thermostats, chances are yours isn’t being made the most of since it’s on “hold” all the time.

When upgrading your thermostat, the Nest smart thermostat is one of the top sellers. That’s because it learns your temperature preferences and activities, and then creates an energy-efficient schedule to match. You can also check and raise it from almost anywhere with your smartphone.

On average, Nest says its thermostat saves about 10-12% on heating costs and about 15% on cooling bills. That’s about $131 to $145 saved each year, which helps it pay for itself faster than two years. And most utility businesses have rebate programs that help you install a smart thermostat for free or close to it.

When you’re installing a smart home thermostat, you’ll want to be sure it will work with your HVAC system. This is especially important if your equipment is older. If it’s not, you might run into issues, like odd furnace or air conditioner behavior. That’s why it’s critical to have a expert like Air Quality Solutions help you select a new thermostat and do your smart thermostat installation.

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

Nest is Compatible with Most Heating and Cooling Systems

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

This involves heating and cooling systems that use:

  • Natural gas
  • Oil
  • Electricity

Before you get a Nest, you can put your details into the Compatibility Checker to provide a simple transition. Once you’ve double-checked it’s compatible, your Nest will guide you through compatibility and wiring when you start using it.

The Nest Learning Thermostat works with the largest number of home comfort units, including heat pumps, furnaces and air conditioners. It also works with extremely energy-efficient multistage systems, dual-fuel equipment, humidifiers and dehumidifiers, but you’ll often need a professional like Air Quality Solutions to handle the in-depth wiring and setup procedures.

Does the Nest Require a C-Wire?

If you’ve done research on the Nest, you’ve probably found info about the C-wire, or common wire. This wire runs your smart thermostat when it can’t get ample power from the other wires.

If you don’t have a C-wire, it’s likely still okay to use a Nest. The company says its thermostats were designed to consume little power. Most of the time, this means they can work normally without this wire.

Have a smart thermostat without a C-wire and running into odd heating and cooling behavior? An HVAC specialist like Air Quality Solutions can add a C-wire for you.
