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

March 10, 2021

If you’re one of the typical American households who spends more than $2,000 every year on utility expenses, getting a smart thermostat is a great way to keep energy costs low. Although most houses rely on programmable thermostats, chances are yours isn’t being made the most of as it’s on “hold” every day.

When getting a new thermostat, the Nest smart thermostat is one of the best sellers. That’s because it learns your temperature preferences and routine, and then creates 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 bills and about 15% on cooling bills. That’s about $131 to $145 saved each year, which helps the product pay for itself in under two years. And the majority of utility providers provide rebate programs that help you purchase a smart thermostat for free or close to it.

When you’re getting a smart home thermostat, you’ll want to make sure it’s compatible with your HVAC system. This is especially essential if your equipment is older. If it’s not, you might experience troubles, like erratic furnace or air conditioner behavior. That’s why it’s important to have a professional like Gillman Heating and Air 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 Works with Most Heating and Cooling Systems

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

This covers heating and cooling systems that run on:

  • Natural gas
  • Oil
  • Electricity

Before you purchase a Nest, you can put your details into the Compatibility Checker to provide a simple transition. Once you’ve confirmed it’s compatible, your Nest will guide you through compatibility and wiring when you set it up.

The Nest Learning Thermostat is compatible with the biggest range of home comfort units, including heat pumps, furnaces and air conditioners. It also runs with extremely energy-efficient multistage systems, dual-fuel equipment, humidifiers and dehumidifiers, but you’ll often need a professional like Gillman Heating and Air to do the in-depth wiring and setup steps.

Does the Nest Have to Have a C-Wire?

If you’ve read up on the Nest, you’ve potentially found information about the C-wire, or common wire. This wire energizes your smart thermostat when it can’t pull ample power from the other wires.

If you don’t have a C-wire, it’s likely still all right to use a Nest. The company says its thermostats were created to use small amounts of power. In most cases, this means they can operate properly without this wire.

Have a smart thermostat without a C-wire and noticing weird heating and cooling behavior? An HVAC specialist like Gillman Heating and Air can install a C-wire for you.
