When you’re seeking methods to reduce utility expenses, getting a smart thermostat is a wise move. These devices learn your favorite temperatures and routine and then develop an energy-efficient schedule that matches. What’s even better is that you can change and watch your settings from nearly anywhere with your phone, whether you’re relaxing in bed or out and about. (You might even be eligible for a free smart thermostat depending on rebate programs from your utility provider in Safford.)
In most instances, hooking up a smart home thermostat with the support of B&D Air Conditioning is a straightforward process if you have a more modern house. But what if your home 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 choose the correct thermostat and get energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
Many programmable thermostats run on batteries. When you’re upgrading to a smart thermostat, you’ll discover 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 ascertain if you have a C wire by doing the following:
- Cut 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 nearly there. Make sure the C wire isn’t tucked in the wall. If you can’t find one, we may be able to install 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 run a smart thermostat with an adaptor designed 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 isn’t right 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 might be a fit for your needs.
Nest says its thermostats are made to consume minimal power and can often share it with your heating and cooling system. However, you may need to have a pro like B&D Air Conditioning 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 constantly drained.
ecobee connects 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.
