When you’re wanting methods to lower heating and cooling costs, getting a smart thermostat is an intelligent 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 regulate and keep an eye on your settings from nearly anywhere with your phone, whether you’re lying 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 Northglenn.)
In most instances, hooking up a smart home thermostat with the support of Northglenn Heating & Air Conditioning is an uncomplicated task if you have a more modern house. But what if your house is older or doesn’t have the right wiring? Can you still install a smart thermostat without C wire? We’ll help you demystify the process so you can choose the recommended thermostat and receive energy savings for many years.
What Is a C Wire and What Does It Do on a Thermostat?
Many programmable thermostats use batteries. When you’re making the move to a smart thermostat, you’ll learn that many require 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 have glitches.
You can determine if you have a C wire by doing the following:
- Cut power to the thermostat at the breaker.
- Pull 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 wondering what color is the C wire on a thermostat—and the answer to that is often blue.
- If there are three or four thin multicolored wires, you’re nearly there. Ensure the C wire isn’t hidden within the wall. If you can’t find one, we may be able to add 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 run a smart thermostat with an adaptor specifically 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 is incompatible and you don’t want to install new wiring.
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 may be a match for your needs.
Nest says its thermostats are designed to consume minimal power and can typically share it with your HVAC system. However, you may need to have a pro like Northglenn Heating & Air Conditioning install a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re running into 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.
