When you’re looking for methods to decrease energy bills, getting a smart thermostat is a smart decision. These devices pick up on your favorite temperatures and routine and then create an energy-efficient schedule to match. What’s even better is that you can regulate and monitor your settings from nearly anywhere with your phone, whether you’re sitting in bed or on the go. (You might even be able to get a free smart thermostat depending on rebate programs from your utility provider in Manassas.)
In many instances, hooking up a smart home thermostat with the help of Fire & Ice HVAC is an uncomplicated task if you have a new 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 choose the ideal thermostat and get energy savings for a long time.
What Is a C Wire and What Does It Do on a Thermostat?
Many programmable thermostats use batteries. When you’re upgrading to a smart thermostat, you’ll find that many need a C wire, or common wire, for power. If you don’t have this wire, your new thermostat may cause your heating and cooling system to malfunction.
You can determine if you have a C wire by doing the following:
- Cut power to the thermostat at the breaker.
- Remove the thermostat and look at the wiring.
- If there are five or six multicolored wires, you have what you need 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 close. Make sure the C wire isn’t tucked in 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 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 install new wiring.
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 could be an option for your needs.
Nest says its thermostats are created to need minimal power and can frequently share it with your HVAC system. However, you may need to have a professional like Fire & Ice HVAC 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 is compatible 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.
