When you’re looking for ways to lower utility expenses, installing a smart thermostat is a wise decision. These devices learn your temperature preferences and routine and then develop an energy-efficient schedule to match. What’s even better is that you can change and monitor your settings from almost anywhere with your phone, whether you’re relaxing in bed or out and about. (You might even be eligible for a free smart thermostat depending on rebate programs from your utility company in Tomball.)
In many instances, adding a smart home thermostat with the assistance of Premium Air Services LLC is a straightforward process if you have a more modern residence. But what if your residence is older or doesn’t have the correct wiring? Can you still add a smart thermostat without C wire? We’ll help you figure out the process so you can pick the ideal thermostat and enjoy energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
Many programmable thermostats run on batteries. When you’re switching to a smart thermostat, you’ll discover that many require a C wire, or common wire, for power. Without this wire, your new thermostat might cause your heating and cooling system to have malfunctions.
You can ascertain if you have a C wire by doing the following:
- Turn off power to the thermostat at the breaker.
- Take off 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 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 nearly there. Ensure the C wire isn’t rolled up in the wall. If you can’t find one, we may be able to put in 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 just 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 won’t work 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 might be a fit for your needs.
Nest says its thermostats are made to run on very little power and can often share it with your HVAC system. However, you may need to have a professional like Premium Air Services LLC add a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re experiencing power problems or a battery that’s constantly drained.
ecobee works 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.
