When you’re wanting methods to decrease utility costs, getting a smart thermostat is a wise move. These devices adjust to your favorite temperatures and routine and then develop an energy-efficient schedule to match. What’s even better is that you can adjust and watch your settings from just about anywhere with your phone, whether you’re sitting in bed or out and about. (You might even be eligible for a free smart thermostat depending on rebate programs from your utility supplier in Northridge.)
In many instances, adding a smart home thermostat with the help of Enertek Air Conditioning & Heating is a simple task 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 pick the right thermostat and enjoy 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 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 may cause your heating and cooling system to have malfunctions.
You can determine if you have a C wire by doing the following:
- Cut power to the thermostat at the breaker.
- Pull off the thermostat and check the wiring.
- If there are five or six multicolored wires, you have what you need 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 tucked inside the wall. If you can’t find one, we may be able to add 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 run 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 won’t work 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 might be a fit for your needs.
Nest says its thermostats are made to require very little power and can frequently share it with your HVAC system. However, you may need to have a specialist like Enertek Air Conditioning & Heating install 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 is compatible with 24-volt systems (ones with three to six thermostat wires) and comes with a C wire adaptor. So, you’re taken care of if you don’t have a thermostat C wire.
