What’s the difference between HRV and ERV?
An HRV transfers heat between the outgoing and incoming air. An ERV transfers heat and moisture, which helps manage indoor humidity.
Why does a Passive House need mechanical ventilation?
Airtight homes don’t rely on leaks for fresh air, so a continuous, controlled ventilation system is needed to maintain indoor air quality.
How often should an HRV/ERV be serviced?
At least annually, with filters changed as the manufacturer recommends.
How much does an HRV or ERV system cost?
It depends on the home’s size, layout and the unit selected. We quote after reviewing the plans.
