When you’re wanting ways to lower utility costs, getting a smart thermostat is a smart idea. These devices pick up on 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 relaxing in bed or away from home. (You might even be able to get a free smart thermostat depending on rebate programs from your utility supplier in Chadron.)
Most of the time, hooking up a smart home thermostat with the support of MPC Heating & Cooling is a simple process if you have a more modern house. But what if your home is older or doesn’t have the correct 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 years to come.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of programmable thermostats use 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. Without 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:
- Turn off power to the thermostat at the breaker.
- Take off the thermostat and look at the wiring.
- If there are five or six multicolored wires, you have what you need 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.
- If there are three or four thin multicolored wires, you’re almost there. Make sure the C wire isn’t hidden in the wall. If you can’t find one, we may be able to put in one for you or you may be able to use your new thermostat without one.
- 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 install a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring won’t work and you don’t want to put in 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 match for your needs.
Nest says its thermostats are created to require minimal power and can often share it with your HVAC system. However, you may need to have a specialist like MPC Heating & Cooling 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 has a C wire adaptor. So, you’re covered if you don’t have a thermostat C wire.
