Evergreen IM is the world's first high-efficiency ECM replacement motor that is designed to replace factory PSC blower motors in HVAC systems. Built from the same trusted, field-proven ECM technology that is found in millions of OEM systems nationwide, Evergreen uses up to 25% fewer watts in operating mode and up to 74% fewer Watts than a PSC motor in constant fan. Evergreen's ECM controls combine thermostat commands with an advanced permanent magnet design to run more efficiently and quietly while offering better airflow control than a PSC. The Evergreen IM is a great replacement for any PSC air-handler motor, adding up to 1 SEER point to an existing system. The motor's airflow benefits are especially important to homeowners who run (or would like to run) in constant fan mode for better comfort, improved IAQ products or improved zoning airflow.
