When you’re seeking ways to decrease utility costs, getting a smart thermostat is an intelligent move. These devices learn your favorite temperatures and routine and then develop an energy-efficient schedule that matches. What’s even better is that you can regulate and keep an eye on your settings from just about anywhere with your phone, whether you’re lying in bed or on the go. (You might even be eligible for a free smart thermostat depending on rebate programs from your utility provider in Paxinos.)

Most of the time, hooking up a smart home thermostat with the support of LTS Plumbing & Heating Inc. is an uncomplicated process if you have a newer house. But what if your residence is older or doesn’t have the correct wiring? Can you still have a smart thermostat without C wire? We’ll help you navigate the process so you can select the right thermostat and receive energy savings for years to come.

What Is a C Wire and What Does It Do on a Thermostat?

The majority of programmable thermostats need batteries. When you’re making the move to a smart thermostat, you’ll find that many have to have a C wire, or common wire, for power. If you don’t have this wire, your new thermostat might cause your heating and cooling system to have glitches.

You can find out if you have a C wire by doing the following:

  1. Turn off power to the thermostat at the breaker.
  2. Remove the thermostat and check the wiring.
  3. If there are five or six multicolored wires, you have what’s needed for a smart thermostat. You might be wondering what color is the C wire on a thermostat—and the answer to that is usually blue.
  4. If there are three or four thin multicolored wires, you’re close. Check the C wire isn’t hidden inside the wall. If you can’t find one, we may be able to install one for you or you may be able to use your new thermostat without one.
  5. If you have two thick wires, you may be able to use a smart thermostat with an adaptor just for high-voltage systems. Or you may be able to operate a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring is incompatible 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 may be a fit for you.

Nest says its thermostats are designed to run on not a lot of power and can often share it with your heating and cooling system. However, you may need to have a professional like LTS Plumbing & Heating Inc. 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 connects 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.
