When you’re seeking approaches to lower energy bills, installing a smart thermostat is a smart decision. These devices pick up on your favorite temperatures and routine and then create an energy-efficient schedule that matches. What’s even better is that you can change and watch your settings from nearly anywhere with your phone, whether you’re sitting in bed or out and about. (You might even be able to get a free smart thermostat depending on rebate programs from your utility supplier in Newark.)
In many instances, adding a smart home thermostat with the assistance of Luikart Heating & Cooling is a straightforward task if you have a newer home. But what if your house is older or doesn’t have the correct wiring? Can you still add a smart thermostat without C wire? We’ll help you demystify the process so you can choose the correct thermostat and enjoy energy savings for a long time.
What Is a C Wire and What Does It Do on a Thermostat?
Most programmable thermostats use batteries. When you’re switching to a smart thermostat, you’ll discover 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 malfunction.
You can ascertain if you have a C wire by doing the following:
- Switch off power to the thermostat at the breaker.
- Remove 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 thinking what color is the C wire on a thermostat—and the answer to that is often blue.
- If there are three or four thin multicolored wires, you’re almost there. Make sure the C wire isn’t tucked within the wall. If you can’t find one, we may be able to add 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 specifically 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 might be an option for you.
Nest says its thermostats are made to require minimal power and can frequently share it with your heating and cooling system. However, you may need to have a pro like Luikart Heating & Cooling add a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re having power problems or a battery that’s constantly drained.
ecobee works with 24-volt systems (ones with three to six thermostat wires) and comes with a C wire adaptor. So, you’re covered if you don’t have a thermostat C wire.
