Energy Recovery Ventilation (ERV) systems play a critical role in indoor air quality, comfort, and overall HVAC efficiency. But designing or replacing an ERV isn’t as simple as matching part numbers—performance goals, building usage, airflow requirements, and code compliance all matter.
Before selecting a replacement or recommending a configuration, take time to define your objectives. Challenge assumptions. A system that worked 10 years ago may no longer be the right fit for today’s occupancy patterns, ventilation needs, or energy demands.
Although ERV technology appears straightforward at first glance, the deeper you dig, the more complex it becomes. Core vs. wheel design, airflow balance, leakage rates, humidity transfer, control strategies—each element impacts performance.
MicroMetl has been deeply involved in ERV technology and integration for decades. While we no longer manufacture standalone ERV units, we continue to support the industry with engineering insight, best practices, and educational guidance.
