When you’re wanting methods to decrease energy expenses, getting a smart thermostat is a smart decision. These devices learn your favorite temperatures and routine and then create an energy-efficient schedule to match. What’s even better is that you can change and monitor your settings from just about 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 Lexington.)
Most of the time, adding a smart home thermostat with the assistance of James Heating & A/C, Inc is a simple job if you have a more modern house. But what if your house is older or doesn’t have the correct wiring? Can you still have a smart thermostat without C wire? We’ll help you figure out the process so you can pick the recommended thermostat and get energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
Most programmable thermostats run on 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. If you don’t have this wire, your new thermostat might cause your heating and cooling system to have malfunctions.
You can ascertain if you have a C wire by doing the following:
- Turn off power to the thermostat at the breaker.
- Remove the thermostat and check the wiring.
- If there are five or six multicolored wires, you have what’s needed for a smart thermostat. You might be wondering 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. Check 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 install a smart thermostat with an adaptor just 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 is incompatible and you don’t want to replace it.
Do Nest or ecobee Need a C Wire?
Two of the most popular brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats may be a match for you.
Nest says its thermostats are designed to need minimal power and can frequently share it with your HVAC system. However, you may need to have a pro like James Heating & A/C, Inc 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 always drained.
ecobee connects 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.
