When you’re seeking ways to reduce energy costs, getting a smart thermostat is a smart 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 regulate and watch your settings from almost anywhere with your phone, whether you’re relaxing 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 Michigan City.)

In many instances, hooking up a smart home thermostat with the help of Paniccia Heating & Cooling is a straightforward job if you have a new house. But what if your home is older or doesn’t have the right wiring? Can you still have a smart thermostat without C wire? We’ll help you demystify the process so you can choose the right thermostat and receive energy savings for years to come.

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

Many programmable thermostats run on batteries. When you’re upgrading to a smart thermostat, you’ll find that many require a C wire, or common wire, for power. If you don’t have this wire, your new thermostat could cause your heating and cooling system to have malfunctions.

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

  1. Cut power to the thermostat at the breaker.
  2. Remove the thermostat and look at the wiring.
  3. 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 usually blue.
  4. If there are three or four thin multicolored wires, you’re almost there. Check the C wire isn’t tucked within 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.
  5. 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 replace it.

Do Nest or ecobee Need a C Wire?

Two of the top brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats might work for your needs.

Nest says its thermostats are created to consume minimal power and can typically share it with your home comfort system. However, you may need to have a specialist like Paniccia 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 frequently drained.

ecobee connects with 24-volt systems (ones with three to six thermostat wires) and includes a C wire adaptor. So, you’re taken care of if you don’t have a thermostat C wire.
