When you’re wanting approaches to decrease heating and cooling costs, getting a smart thermostat is a smart move. These devices learn your favorite temperatures and routine and then make 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 relaxing in bed or away from home. (You might even be eligible for a free smart thermostat depending on rebate programs from your utility provider in Erie.)
In many instances, hooking up a smart home thermostat with the assistance of Patterson & Stirling is a straightforward job if you have a newer house. But what if your house is older or doesn’t have the right wiring? Can you still have a smart thermostat without C wire? We’ll help you figure out the process so you can choose the recommended thermostat and get energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of programmable thermostats need 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. Without this wire, your new thermostat may cause your heating and cooling system to have glitches.
You can find out if you have a C wire by doing the following:
- Switch off power to the thermostat at the breaker.
- Take off 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 usually blue.
- If there are three or four thin multicolored wires, you’re close. Ensure the C wire isn’t hidden 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 operate your new thermostat without one.
- If you have two thick wires, you may be able to install 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 isn’t right and you don’t want to put in 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 you.
Nest says its thermostats are made to need not a lot of power and can frequently share it with your HVAC system. However, you may need to have a specialist like Patterson & Stirling add a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re having power problems or a battery that’s frequently drained.
ecobee connects with 24-volt systems (ones with three to six thermostat wires) and comes with a C wire adaptor. So, you’re good if you don’t have a thermostat C wire.
