When you’re wanting approaches to reduce utility costs, getting a smart thermostat is a wise decision. These devices pick up on your favorite temperatures and routine and then make an energy-efficient schedule that matches. What’s even better is that you can adjust and monitor your settings from nearly anywhere with your phone, whether you’re sitting in bed or out and about. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility provider in Longview.)
In many instances, adding a smart home thermostat with the help of Goode Bros AC & Heating is a straightforward process if you have a more modern house. But what if your residence is older or doesn’t have the proper wiring? Can you still install a smart thermostat without C wire? We’ll help you navigate the process so you can choose the proper thermostat and receive energy savings for many years.
What Is a C Wire and What Does It Do on a Thermostat?
Most 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 may cause your heating and cooling system to have glitches.
You can find out if you have a C wire by doing the following:
- Switch off power to the thermostat at the breaker.
- Take off the thermostat and find the wiring.
- If there are five or six multicolored wires, you have what’s required for a smart thermostat. You might be pondering what color is the C wire on a thermostat—and the answer to that is typically blue.
- If there are three or four thin multicolored wires, you’re nearly there. Ensure the C wire isn’t hidden within the wall. If you can’t find one, we may be able to install 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 designed 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 won’t work and you don’t want to replace it.
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 be a fit for you.
Nest says its thermostats are created to require minimal power and can typically share it with your heating and cooling system. However, you may need to have a pro like Goode Bros AC & Heating put in a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re experiencing power problems or a battery that’s frequently drained.
ecobee works with 24-volt systems (ones with three to six thermostat wires) and comes with a C wire adaptor. So, you’re good if you don’t have a thermostat C wire.
