When you’re wanting approaches to lower utility costs, getting a smart thermostat is a smart decision. These devices learn your favorite temperatures and routine and then develop an energy-efficient schedule to match. What’s even better is that you can regulate and watch your settings from nearly anywhere with your phone, whether you’re lying in bed or on the go. (You might even be able to get a free smart thermostat depending on rebate programs from your utility provider in Justin.)
In most instances, hooking up a smart home thermostat with the help of Pepper AC & Heat is an uncomplicated process if you have a more modern house. But what if your home is older or doesn’t have the proper wiring? Can you still install a smart thermostat without C wire? We’ll help you navigate the process so you can select the proper thermostat and receive energy savings for many years.
What Is a C Wire and What Does It Do on a Thermostat?
Many programmable thermostats need batteries. When you’re switching to a smart thermostat, you’ll find that many require 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 malfunction.
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 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 often blue.
- If there are three or four thin multicolored wires, you’re almost there. Make sure the C wire isn’t rolled up in the wall. If you can’t find one, we may be able to add 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 run a smart thermostat with an adaptor specifically for high-voltage systems. Or you may be able to install a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring won’t work 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 could be a match for your home.
Nest says its thermostats are made to consume minimal power and can often share it with your HVAC system. However, you may need to have a professional like Pepper AC & Heat 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 is compatible 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.
