When you’re wanting methods to decrease utility costs, getting a smart thermostat is a wise idea. These devices pick up on your favorite temperatures and routine and then make an energy-efficient schedule that fits. What’s even better is that you can adjust and watch your settings from almost anywhere with your phone, whether you’re sitting 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 Narvon.)
In most instances, adding a smart home thermostat with the support of Ameri-Tec is a simple job if you have a newer house. But what if your house is older or doesn’t have the correct wiring? Can you still have a smart thermostat without C wire? We’ll help you navigate the process so you can pick the right 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 making the move to a smart thermostat, you’ll learn that many need a C wire, or common wire, for power. If you don’t use this wire, your new thermostat may cause your heating and cooling system to malfunction.
You can find out if you have a C wire by doing the following:
- Cut 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’s needed 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 almost there. Check the C wire isn’t hidden in the wall. If you can’t find one, we may be able to install 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 use a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring isn’t right 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 made to consume minimal power and can frequently share it with your HVAC system. However, you may need to have a professional like Ameri-Tec install a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re experiencing power problems or a battery that’s always drained.
ecobee is compatible with 24-volt systems (ones with three to six thermostat wires) and has a C wire adaptor. So, you’re good if you don’t have a thermostat C wire.
