When you’re looking for methods to lower utility expenses, getting a smart thermostat is a wise decision. 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 change and keep an eye on your settings from just about anywhere with your phone, whether you’re relaxing in bed or out and about. (You might even be able to get a free smart thermostat depending on rebate programs from your utility company in Cape Coral.)
In most instances, installing a smart home thermostat with the help of Comfort Zone Inc is an uncomplicated process if you have a new house. But what if your house is older or doesn’t have the correct wiring? Can you still install a smart thermostat without C wire? We’ll help you navigate the process so you can choose the recommended thermostat and enjoy energy savings for a long time.
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 learn that many need a C wire, or common wire, for power. If you don’t have this wire, your new thermostat could cause your heating and cooling system to have glitches.
You can find out if you have a C wire by doing the following:
- Turn off power to the thermostat at the breaker.
- Pull off the thermostat and check the wiring.
- If there are five or six multicolored wires, you have what you need for a smart thermostat. You might be pondering what color is the C wire on a thermostat—and the answer to that is often blue.
- If there are three or four thin multicolored wires, you’re close. Make sure the C wire isn’t hidden in the wall. If you can’t find one, we may be able to add 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 operate a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring is incompatible and you don’t want to replace it.
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 home.
Nest says its thermostats are made to require minimal power and can frequently share it with your HVAC system. However, you may need to have a specialist like Comfort Zone Inc install a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re running into 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.
