When you’re seeking approaches to reduce energy bills, getting a smart thermostat is an intelligent move. These devices adjust to your favorite temperatures and routine and then make an energy-efficient schedule that fits. What’s even better is that you can regulate and monitor your settings from nearly anywhere with your phone, whether you’re lying in bed or on the go. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility supplier in Lake Worth.)
In many instances, installing a smart home thermostat with the assistance of Smyth Air Conditioning is an uncomplicated job if you have a more modern house. But what if your residence is older or doesn’t have the right wiring? Can you still have a smart thermostat without C wire? We’ll help you demystify the process so you can select the ideal 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 switching to a smart thermostat, you’ll find that many need a C wire, or common wire, for power. If you don’t have this wire, your new thermostat may cause your heating and cooling system to have glitches.
You can determine if you have a C wire by doing the following:
- Switch off power to the thermostat at the breaker.
- Take off the thermostat and check 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 close. Check the C wire isn’t hidden 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 run 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 won’t work and you don’t want to put in 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 work for your needs.
Nest says its thermostats are created to consume not a lot of power and can typically share it with your heating and cooling system. However, you may need to have a professional like Smyth 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 is compatible 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.
