When you’re looking for ways to reduce energy bills, getting a smart thermostat is an intelligent decision. These devices learn your favorite temperatures and routine and then create an energy-efficient schedule that matches. What’s even better is that you can regulate and watch your settings from just about anywhere with your phone, whether you’re relaxing in bed or away from home. (You might even be eligible for a free smart thermostat depending on rebate programs from your utility provider in Muldrow.)
Most of the time, installing a smart home thermostat with the support of Air Service Co. is a straightforward task if you have a new house. But what if your house is older or doesn’t have the right wiring? Can you still add a smart thermostat without C wire? We’ll help you demystify the process so you can select the ideal thermostat and get 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 switching to a smart thermostat, you’ll find that many have to have 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 have glitches.
You can determine if you have a C wire by doing the following:
- Switch 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 you need 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 almost there. Check the C wire isn’t rolled up 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 specifically 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 isn’t right 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 match for your needs.
Nest says its thermostats are made to require not a lot of power and can often share it with your HVAC system. However, you may need to have a specialist like Air Service Co. install a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re running into power problems or a battery that’s always 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.
