Advanced Rooftop Unit Control (ARC) rebates are available only for qualifying retrofits installed on an existing Rooftop Unit (RTU). Heating fuel may be electric or gas.

Pre-condition requirements for existing RTU:

• Cooling capacity equal to or greater than five tons
• Unitary system (split systems are not eligible)
• Constant-speed supply fan (RTUs with variable speed fans are not eligible)

Retrofit-Lite: $80 per ton

ARC-Lite products add one of the following equipment options to the existing RTU:

• VFD and controller for variable speed fan operation; or
• Multispeed motor and controller for multispeed fan operation

Retrofit-Full: $175 per ton

In addition to one of the ARC-Lite options, Full-ARC products also add a controller with all of the following enabled:

• Digital, integrated economizer control with either differential dry-bulb, or differential enthalpy with fixed dry-bulb high-limit shutoff; and
• Demand Control Ventilation with proportional control, based on CO2 sensor reading

The ARC must be listed on Bonneville Power Administration’s qualified products list.

ARC projects are not eligible for the Connected Thermostat rebate.
To calculate the projected rebate, either:

1. Sum the tons from all heat pumps installed, then round to the nearest whole ton; or
2. Round each individual heat pump to the nearest whole ton, then sum all rounded tons.

Rebate(s) will not exceed 100% of the installed job cost.

Please allow 6 to 8 weeks after receipt of all required documentation for rebate checks to be issued and mailed.
