When you’re looking for ways to decrease utility bills, getting a smart thermostat is a smart decision. These devices adjust to your favorite temperatures and routine and then develop an energy-efficient schedule to match. What’s even better is that you can regulate and watch your settings from almost anywhere with your phone, whether you’re lying in bed or on the go. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility supplier in Elk River.)
In most instances, adding a smart home thermostat with the support of Home Comfort Heating & Air is a straightforward job if you have a more modern house. But what if your home is older or doesn’t have the proper wiring? Can you still have a smart thermostat without C wire? We’ll help you navigate the process so you can pick the proper thermostat and enjoy energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of programmable thermostats run on batteries. When you’re upgrading to a smart thermostat, you’ll learn that many need a C wire, or common wire, for power. Without this wire, your new thermostat might cause your heating and cooling system to have malfunctions.
You can find out if you have a C wire by doing the following:
- Cut power to the thermostat at the breaker.
- Pull off the thermostat and check the wiring.
- If there are five or six multicolored wires, you have what’s needed for a smart thermostat. You might be thinking what color is the C wire on a thermostat—and the answer to that is often blue.
- If there are three or four thin multicolored wires, you’re nearly there. Ensure the C wire isn’t tucked within the wall. If you can’t find one, we may be able to add one for you or you may be able to operate your new thermostat without one.
- If you have two thick wires, you may be able to run a smart thermostat with an adaptor specifically for high-voltage systems. Or you may be able to use a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring won’t work and you don’t want to install new wiring.
Do Nest or ecobee Need a C Wire?
Two of the best-selling brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats might work for your home.
Nest says its thermostats are created to run on not a lot of power and can frequently share it with your heating and cooling system. However, you may need to have a specialist like Home Comfort Heating & Air add a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re experiencing power problems or a battery that’s always drained.
ecobee is compatible with 24-volt systems (ones with three to six thermostat wires) and includes a C wire adaptor. So, you’re good if you don’t have a thermostat C wire.
