When you’re wanting approaches to lower energy costs, getting a smart thermostat is a smart decision. These devices adjust to your favorite temperatures and routine and then create an energy-efficient schedule that matches. What’s even better is that you can change and keep an eye on your settings from almost anywhere with your phone, whether you’re lying in bed or on the go. (You might even be eligible for a free smart thermostat depending on rebate programs from your utility company in Bartlesville.)
In most instances, installing a smart home thermostat with the support of Farris Heating & Air is a straightforward process if you have a more modern 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 navigate the process so you can choose the correct thermostat and receive energy savings for many years.
What Is a C Wire and What Does It Do on a Thermostat?
Most programmable thermostats use batteries. When you’re making the move to a smart thermostat, you’ll find that many need a C wire, or common wire, for power. If you don’t use this wire, your new thermostat could cause your heating and cooling system to have glitches.
You can ascertain if you have a C wire by doing the following:
- Switch off power to the thermostat at the breaker.
- Take off the thermostat and find the wiring.
- If there are five or six multicolored wires, you have what you need for a smart thermostat. You might be pondering 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. Ensure 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 use 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 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 replace it.
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 may be a match for your needs.
Nest says its thermostats are created to consume very little power and can frequently share it with your HVAC system. However, you may need to have a pro like Farris Heating & Air put in a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re experiencing power problems or a battery that’s constantly drained.
ecobee is compatible with 24-volt systems (ones with three to six thermostat wires) and includes a C wire adaptor. So, you’re taken care of if you don’t have a thermostat C wire.
