Check a quoted HRV or ERV
check_ventilation_unitRead-only
Checks a quoted HRV or ERV against bedroom airflow needs using exact-model HVI-certified data. Returns a screening verdict, reasons, assumptions and questions for the installer. Ambiguous model names return candidates for clarification rather than a guessed model. Does not provide a permit-ready design or guarantee installation performance.
