When you’re seeking approaches to lower heating and cooling bills, getting a smart thermostat is a wise idea. 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 change and keep an eye on your settings from just about anywhere with your phone, whether you’re lying in bed or away from home. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility supplier in Thedford.)
In many instances, installing a smart home thermostat with the help of Taylor's Heating & Air Conditioning is a simple process 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 demystify the process so you can choose the right thermostat and enjoy energy savings for a long time.
What Is a C Wire and What Does It Do on a Thermostat?
Most programmable thermostats run on batteries. When you’re making the move to a smart thermostat, you’ll find that many need a C wire, or common wire, for power. If you don’t use this wire, your new thermostat could cause your heating and cooling system to malfunction.
You can determine if you have a C wire by doing the following:
- Switch off 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 required for a smart thermostat. You might be wondering 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 close. Ensure the C wire isn’t rolled up within the wall. If you can’t find one, we may be able to put in 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 specifically 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 install new wiring.
Do Nest or ecobee Need a C Wire?
Two of the top brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats might be a match for your home.
Nest says its thermostats are designed to consume very little power and can often share it with your home comfort system. However, you may need to have a specialist like Taylor's 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 comes with a C wire adaptor. So, you’re good if you don’t have a thermostat C wire.
