When you’re seeking approaches to decrease energy expenses, getting a smart thermostat is a smart decision. These devices learn your favorite temperatures and routine and then make an energy-efficient schedule that matches. What’s even better is that you can change and monitor your settings from nearly anywhere with your phone, whether you’re relaxing in bed or out and about. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility company in Hodgenville.)
Most of the time, adding a smart home thermostat with the assistance of Phelps Heating & Cooling, Inc. is a simple task if you have a newer house. But what if your house is older or doesn’t have the correct wiring? Can you still add a smart thermostat without C wire? We’ll help you figure out the process so you can select the recommended thermostat and get energy savings for years to come.
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 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 malfunctions.
You can ascertain if you have a C wire by doing the following:
- Cut power to the thermostat at the breaker.
- Remove the thermostat and find the wiring.
- If there are five or six multicolored wires, you have what’s needed 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 nearly there. Ensure the C wire isn’t tucked in the wall. If you can’t find one, we may be able to put in 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 install a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring won’t work and you don’t want to install 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 work for you.
Nest says its thermostats are made to need not a lot of power and can often share it with your HVAC system. However, you may need to have a specialist like Phelps Heating & Cooling, Inc. put in a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re having power problems or a battery that’s frequently drained.
ecobee is compatible with 24-volt systems (ones with three to six thermostat wires) and comes with a C wire adaptor. So, you’re taken care of if you don’t have a thermostat C wire.
