When you’re wanting ways to lower energy costs, getting a smart thermostat is an intelligent decision. These devices pick up on your favorite temperatures and routine and then develop an energy-efficient schedule that fits. What’s even better is that you can adjust and watch your settings from almost anywhere with your phone, whether you’re lying in bed or away from home. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility supplier in Manassas.)
In most instances, hooking up a smart home thermostat with the help of Woody's Sudden Service is a simple process if you have a new house. But what if your residence 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 receive energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
Most programmable thermostats need batteries. When you’re upgrading to a smart thermostat, you’ll learn that many need a C wire, or common wire, for power. If you don’t use this wire, your new thermostat may cause your heating and cooling system to malfunction.
You can find out if you have a C wire by doing the following:
- Turn off power to the thermostat at the breaker.
- Take off 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 nearly there. Ensure the C wire isn’t tucked inside 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 use a smart thermostat with an adaptor designed 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 isn’t right and you don’t want to replace it.
Do Nest or ecobee Need a C Wire?
Two of the top brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats may be a match for your home.
Nest says its thermostats are designed to consume not a lot of power and can frequently share it with your HVAC system. However, you may need to have a professional like Woody's Sudden Service add a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re experiencing power problems or a battery that’s frequently drained.
ecobee works 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.
