When you’re seeking approaches to lower utility costs, getting a smart thermostat is a smart idea. These devices adjust to your favorite temperatures and routine and then make an energy-efficient schedule to match. What’s even better is that you can regulate and monitor your settings from almost anywhere with your phone, whether you’re relaxing in bed or away from home. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility provider in Albuquerque.)
Most of the time, hooking up a smart home thermostat with the help of I-Deal HVAC is a simple job if you have a new house. But what if your house is older or doesn’t have the right wiring? Can you still install a smart thermostat without C wire? We’ll help you demystify the process so you can select the correct thermostat and receive energy savings for a long time.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of programmable thermostats run on batteries. When you’re switching to a smart thermostat, you’ll discover 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 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 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 nearly there. Check the C wire isn’t tucked 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 install a smart thermostat with an adaptor just 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 is incompatible and you don’t want to replace it.
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 may be an option for your needs.
Nest says its thermostats are made to consume minimal power and can frequently share it with your HVAC system. However, you may need to have a pro like I-Deal HVAC add 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 includes a C wire adaptor. So, you’re good if you don’t have a thermostat C wire.
