Today's homes are designed to be more energy-efficient than ever before. Better insulation, highly airtight windows, tightly sealed exterior doors, and improved construction methods help reduce heating and cooling losses.
However, as buildings become more airtight, uncontrolled air leakage decreases. Without properly designed mechanical ventilation, stale air, CO₂, moisture, odors, and indoor pollutants can accumulate.
HRV and ERV systems provide a controlled way to introduce fresh outdoor air and remove stale indoor air while recovering energy that would otherwise be wasted.
