When you’re looking for methods to decrease heating and cooling expenses, getting a smart thermostat is a wise decision. These devices learn your favorite temperatures and routine and then create an energy-efficient schedule to match. What’s even better is that you can adjust and keep an eye on your settings from nearly anywhere with your phone, whether you’re relaxing in bed or on the go. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility company in Neptune City.)
Most of the time, hooking up a smart home thermostat with the assistance of Aggressive Mechanical is a simple process if you have a newer house. But what if your home is older or doesn’t have the correct wiring? Can you still install a smart thermostat without C wire? We’ll help you figure out the process so you can select the proper thermostat and receive energy savings for many years.
What Is a C Wire and What Does It Do on a Thermostat?
Most programmable thermostats run on batteries. When you’re making the move to a smart thermostat, you’ll find that many require 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 malfunctions.
You can ascertain if you have a C wire by doing the following:
- Cut 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 required for a smart thermostat. You might be pondering 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 close. Check the C wire isn’t hidden inside 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 install 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 is incompatible and you don’t want to replace it.
Do Nest or ecobee Need a C Wire?
Two of the best-selling 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 consume very little power and can typically share it with your HVAC system. However, you may need to have a specialist like Aggressive Mechanical add a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re running into power problems or a battery that’s frequently drained.
ecobee connects 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.
