Product Benefits

Installation is Easy

The Nest Power Connector doesn’t require any new wiring or drilling. It attaches to your furnace, air handler or zone controller and comes with simple instructions for easy installation.

Costs Less than a new C-Wire

The Nest Power Connector is affordable and costs much less than hiring an electrician to install a new C-wire through your walls.

Thoughtfully Designed

The Nest Power Connector resists dust and water, and is made from 46% recycled plastic. The wire connectors and sticky pad are designed for an easy, mess-free installation.

Made by Nest

Other C-wire accessories require you to install one piece at the furnace or air handler, and a second one behind the thermostat. The Nest Power Connector requires only one simple connection. And because it’s designed by Nest specifically for Nest thermostats, you can install it with confidence.

Heat-Only Systems

The Nest Power Connector is the first single-piece C-wire substitute that works with two-wire 24 VAC heat-only systems.



Requires a compatible Nest thermostat and HVAC system.
