When you’re seeking methods to lower energy expenses, getting a smart thermostat is a smart move. These devices pick up on 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 nearly anywhere with your phone, whether you’re sitting in bed or away from home. (You might even be able to get a free smart thermostat depending on rebate programs from your utility provider in Phoenix.)
In most instances, hooking up a smart home thermostat with the help of Dial One Mears Air Conditioning & Heating Inc is a simple task if you have a newer house. But what if your house is older or doesn’t have the proper wiring? Can you still add a smart thermostat without C wire? We’ll help you navigate the process so you can pick the ideal thermostat and enjoy energy savings for many years.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of programmable thermostats use batteries. When you’re switching to a smart thermostat, you’ll find that many have to have a C wire, or common wire, for power. Without this wire, your new thermostat may 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.
- Remove the thermostat and check the wiring.
- If there are five or six multicolored wires, you have what’s needed 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 nearly there. Make sure the C wire isn’t hidden within the wall. If you can’t find one, we may be able to install 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 operate a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring won’t work and you don’t want to replace it.
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 home.
Nest says its thermostats are created to need minimal power and can typically share it with your heating and cooling system. However, you may need to have a specialist like Dial One Mears Air Conditioning & Heating 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 constantly drained.
ecobee works 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.
