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

March 10, 2021

If you’re among the average American households who spends more than $2,000 every year on energy bills, adding a smart thermostat is a fantastic way to keep utility expenses under control. Although the majority of residences rely on programmable thermostats, yours probably isn’t being maximized since it’s on “hold” all the time.

When getting a new thermostat, the Nest smart thermostat is one of the best 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 lower it from nearly anywhere with your smartphone.

On average, Nest says its thermostat saves about 10-12% on heating expenses and about 15% on cooling bills. That’s about $131 to $145 saved each year, which helps the thermostat pay for itself quicker than two years. And most utility companies provide 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 ensure it’s compatible with your HVAC system. This is especially essential if your equipment is aging. If it’s not, you may experience problems, like odd furnace or air conditioner behavior. That’s why it’s important to have a pro like Allstar Heating & Air Conditioning help you select a new thermostat and handle your smart thermostat installation.

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

Nest Runs with Most Heating and Cooling Systems

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

This includes heating and cooling systems that use:

  • Natural gas
  • Oil
  • Electricity

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

The Nest Learning Thermostat can run with the biggest types of home comfort equipment, including heat pumps, furnaces and air conditioners. It also operates with highly energy-efficient multistage systems, dual-fuel equipment, humidifiers and dehumidifiers, but you’ll often need a specialist like Allstar Heating & Air Conditioning to handle the complicated wiring and setup procedures.

Does the Nest Need a C-Wire?

If you’ve read up on the Nest, you’ve likely come across 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 ok to install a Nest. The company says its thermostats were made to use little power. Many times, this means they can run properly without this wire.

Have a smart thermostat without a C-wire and running into strange heating and cooling behavior? An HVAC pro like Allstar Heating & Air Conditioning can add a C-wire for you.
