When you’re seeking approaches to reduce utility bills, getting a smart thermostat is a wise 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 monitor your settings from just about anywhere with your phone, whether you’re sitting in bed or out and about. (You might even be eligible for a free smart thermostat depending on rebate programs from your utility company in Omaha.)
In many instances, adding a smart home thermostat with the help of Interstate Heating & Air Conditioning is a simple process if you have a new house. But what if your house is older or doesn’t have the right wiring? Can you still have a smart thermostat without C wire? We’ll help you navigate the process so you can choose the correct thermostat and get energy savings for a long time.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of programmable thermostats run on batteries. When you’re making the move to a smart thermostat, you’ll learn that many need a C wire, or common wire, for power. If you don’t use this wire, your new thermostat could cause your heating and cooling system to malfunction.
You can determine if you have a C wire by doing the following:
- Switch off power to the thermostat at the breaker.
- Pull off the thermostat and look at the wiring.
- If there are five or six multicolored wires, you have what’s required 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 close. Ensure the C wire isn’t rolled up 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 run your new thermostat without one.
- If you have two thick wires, you may be able to use 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 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 could be an option for your needs.
Nest says its thermostats are made to need very little power and can typically share it with your heating and cooling system. However, you may need to have a professional like Interstate Heating & Air Conditioning put in a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re having power problems or a battery that’s frequently drained.
ecobee works with 24-volt systems (ones with three to six thermostat wires) and includes a C wire adaptor. So, you’re covered if you don’t have a thermostat C wire.
