When you’re seeking approaches to lower energy costs, getting a smart thermostat is a wise decision. These devices pick up on the temperatures you like and routine and then develop an energy-efficient schedule that matches. What’s even better is that you can change and monitor your settings from nearly anywhere with your phone, whether you’re relaxing in bed or out and about. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility company in Pacheco.)
Most of the time, installing a smart home thermostat with the assistance of Clean Air HVAC is an uncomplicated job if you have a more modern house. But what if your residence is older or doesn’t have the proper wiring? Can you still install a smart thermostat without C wire? We’ll help you figure out the process so you can pick the right thermostat and enjoy energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of programmable thermostats run on batteries. When you’re switching to a smart thermostat, you’ll discover that many need 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 find out if you have a C wire by doing the following:
- Switch off 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 typically blue.
- If there are three or four thin multicolored wires, you’re nearly there. Ensure the C wire isn’t tucked 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 operate 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 install a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring isn’t right 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 work for your needs.
Nest says its thermostats are designed to require very little power and can typically share it with your HVAC system. However, you may need to have a specialist like Clean Air HVAC install a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re experiencing power problems or a battery that’s frequently drained.
ecobee is compatible 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.
