When you’re wanting methods to reduce energy expenses, 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 adjust and monitor your settings from nearly anywhere with your phone, whether you’re sitting in bed or on the go. (You might even be able to get a free smart thermostat depending on rebate programs from your utility supplier in Warrenton.)
In many instances, installing a smart home thermostat with the assistance of Schraer Heating & Air Conditioning is a simple process if you have a new house. But what if your house is older or doesn’t have the proper wiring? Can you still add a smart thermostat without C wire? We’ll help you demystify the process so you can choose the ideal 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 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 might cause your heating and cooling system to malfunction.
You can determine if you have a C wire by doing the following:
- Turn 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’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 usually blue.
- If there are three or four thin multicolored wires, you’re almost 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 run 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 operate a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring won’t work and you don’t want to put in new wiring.
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 might be a fit for you.
Nest says its thermostats are designed to require minimal power and can typically share it with your HVAC system. However, you may need to have a specialist like Schraer Heating & Air Conditioning 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 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.
