When you’re seeking methods to decrease energy bills, getting a smart thermostat is a wise 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 just about anywhere with your phone, whether you’re relaxing in bed or away from home. (You might even be able to get a free smart thermostat depending on rebate programs from your utility provider in Wyandotte.)
In many instances, installing a smart home thermostat with the support of Gee & Missler Heating & Air Conditioning is a straightforward job if you have a more modern house. But what if your house is older or doesn’t have the correct wiring? Can you still have a smart thermostat without C wire? We’ll help you demystify the process so you can choose the correct thermostat and receive 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 learn that many require a C wire, or common wire, for power. Without this wire, your new thermostat could cause your heating and cooling system to have malfunctions.
You can determine 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’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 typically blue.
- If there are three or four thin multicolored wires, you’re almost there. Ensure the C wire isn’t hidden within the wall. If you can’t find one, we may be able to install one for you or you may be able to run your new thermostat without one.
- If you have two thick wires, you may be able to use a smart thermostat with an adaptor specifically for high-voltage systems. Or you may be able to operate 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 most popular brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats could be an option for your home.
Nest says its thermostats are created to require not a lot of power and can typically share it with your HVAC system. However, you may need to have a specialist like Gee & Missler Heating & Air Conditioning add a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re running into power problems or a battery that’s frequently drained.
ecobee connects with 24-volt systems (ones with three to six thermostat wires) and has a C wire adaptor. So, you’re covered if you don’t have a thermostat C wire.
