When you’re wanting approaches to reduce energy expenses, upgrading to a smart thermostat is a smart move. These devices learn your temperature preferences and routine and then make an energy-efficient schedule that matches. What’s even better is that you can adjust and keep an eye on your settings from just about anywhere with your phone, whether you’re relaxing in bed or out and about. (You might even be able to get a free smart thermostat depending on rebate programs from your utility company in Tuscaloosa.)
In many instances, installing a smart home thermostat with the support of KDM Service Corporation is a simple task if you have a new home. But what if your house is older or doesn’t have the correct wiring? Can you still install a smart thermostat without C wire? We’ll help you demystify the process so you can select the right thermostat and enjoy energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of programmable thermostats need batteries. When you’re making the move to a smart thermostat, you’ll find that many require a C wire, or common wire, for power. If you don’t use this wire, your new thermostat might cause your heating and cooling system to have glitches.
You can determine 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 required for a smart thermostat. You might be pondering 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 nearly there. Make sure the C wire isn’t tucked within the wall. If you can’t find one, we may be able to install 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 put in 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 work for your home.
Nest says its thermostats are made to consume very little power and can often share it with your home comfort system. However, you may need to have a pro like KDM Service Corporation 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 always 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.
