Solving the C-Wire Problem
Most Portland homes built before 2000 lack a common wire. Without steady 24V power, smart thermostats reboot, drain batteries quickly, or drop Wi-Fi. Here are reliable solutions we use in the field.
Ecobee Power Extender Kit (PEK)
Included with every Ecobee thermostat. Installs inside the furnace control board and uses existing wires to simulate a common wire. Takes about 15 minutes for a technician and works with most furnaces and heat pumps.
Nest Power Connector
External adapter that adds stable power for Nest without running new wire. Ideal for condos where pulling new thermostat wire is difficult.
Run New 18/8 Thermostat Cable
Best long-term solution for older Laurelhurst and Sellwood homes. Provides enough conductors for heat pumps, dual fuel, and accessories like humidifiers. Expect $150–$350 depending on wall access.
Add-on Transformer (Avoid if Possible)
Plug-in transformers provide 24V power but create exposed wiring and are not Energy Trust approved. Use only as a temporary measure with professional guidance.
Rebates & Incentives (Energy Trust, PGE)
Stack rebates and bill credits for maximum savings. We submit Energy Trust applications within 48 hours and provide documentation for utility demand-response programs.

DIY vs Professional Installation
Many homeowners can install a smart thermostat in under an hour, but complex systems (dual fuel, zoning, boilers) benefit from professional setup. Use this step-by-step guide to decide.
Efficiency Heating & Cooling provides turnkey installation, wiring upgrades, thermostat programming, and rebate paperwork. We also integrate thermostats with indoor air quality systems and whole-home humidifiers.
1. Confirm Compatibility
Photograph existing thermostat wiring and furnace control board. Use manufacturer compatibility checkers or schedule a consultation. Systems with high-voltage baseboard heaters require different thermostats.
2. Power Down & Label Wires
Turn off power at the furnace/air handler breaker. Label wires by terminal (R, Y, W, G, C). Take clear photos before disconnecting. This prevents miswiring when you attach the new base plate.
3. Install Base Plate & Connect Wires
Mount the new thermostat base plate level. Connect wires to matching terminals. Use supplied adapter kits if no C-wire exists. Avoid overtightening screws on older solid-core wires.
4. Restore Power & Configure Settings
Turn power back on and complete setup on the thermostat screen and mobile app. Program equipment type (heat pump vs furnace), stages, and auxiliary heat lockout temperatures.
5. Enroll in Rebates & Automations
Register the thermostat with Energy Trust, connect to PGE/Pacific Power programs, and integrate with home assistants (Alexa, Google, HomeKit). Set up alerts for filter changes and smoke events.
