When you’re seeking methods to reduce energy expenses, getting a smart thermostat is a smart move. These devices learn your favorite temperatures and routine and then make an energy-efficient schedule that fits. 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 able to get a free smart thermostat depending on rebate programs from your utility supplier in Cambridge.)
In most instances, adding a smart home thermostat with the assistance of Pliescott HVAC Services LLC is an uncomplicated task if you have a newer residence. But what if your house is older or doesn’t have the proper wiring? Can you still add a smart thermostat without C wire? We’ll help you navigate the process so you can pick the recommended thermostat and get energy savings for a long time.
What Is a C Wire and What Does It Do on a Thermostat?
Many programmable thermostats run on batteries. When you’re switching to a smart thermostat, you’ll discover that many require 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:
- 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 needed 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. Check the C wire isn’t rolled up 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 operate 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 use a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring is incompatible and you don’t want to put in new wiring.
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 could be a fit for your needs.
Nest says its thermostats are created to need very little power and can typically share it with your heating and cooling system. However, you may need to have a pro like Pliescott HVAC Services LLC 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 good if you don’t have a thermostat C wire.
