At Home

Heat Recovery VentilationHeat recovery ventilation (HRV) and energy recovery ventilation (ERV) systems provide balanced ventilation for homes. In a typical installation, stale air is removed from living spaces, passing through a central unit that reclaims the heat from the exhaust air, and then warms, filters, and humidifies the incoming fresh air. Many systems operate continuously, quietly, and efficiently while maintaining proper ventilation.
Certain HRV/ERV systems installed in your Oregon home may be eligible for a Residential Energy Tax Credit.

RET​C Qualifications

An installed HRV/ERV system must meet certain qualifications to earn a Residential Energy Tax Credit, valued at 50 percent of the cost of the device, up to $645, depending on the system type and its energy use. See the RETC Rate Chart for more information.

Qualifying HRV/ERV systems must:

  • ​Be tested, rated, and certified through the Home Ventilating Institute.
  • Meet minimum efficiency ratings.
  • Have a maximum Energy Use Index of 1.10 at the lowest fan speed. EUI is calculated by dividing the system's power consumption in watts by the net supply of air delivered (in cubic feet per minute).
RETC Rules require that we u​se Home Ventilating Institute specifications to approve or deny applications. Do not rely on manufacturer's reported specifications when choosing your equipment.
