A whole-house HRV connects to ducts and recovers heat but not moisture, which suits cold climates where a tight house builds up humidity in winter. Look for a defrost system if winter nights go well below freezing, since frost on the core blocks airflow. Airflow is the net supply at 0.4 in of static pressure from the HVI directory, a typical resistance for a ducted install.
