Our ventilation control systems help protect families by allowing tightly-built, energy-efficient homes to “breathe”, bringing in fresh clean air while expelling stale air.

The heat recovery ventilator (HRV) is designed to provide continuous or timed ventilation throughout a home, and recover the heat carried in the exhausted stale air.

The HRV provides several unique benefits as a mechanical ventilation system. First, it is a balanced-type ventilation system, meaning it removes and replaces equal volumes of air from the home. No pressure imbalances occur in the house because of the HRV operating, which improves energy efficiency, comfort and safety.

The HRV alone will not cause combustion appliance backdrafting, increased vapor transmission into the structure and insulation of the house, or cold drafts.

The HRV can replace several bath and utility room fans with a single high-quality, long-lived system, which may run continuously or intermittently.

The HRV recovers up to 90% of the heat in the exhaust air, and returns it to the home. Some HRVs (properly called Energy Recovery Ventilators, or ERVs) will recover moisture from the exhaust stream as well, helping to maintain indoor humidity in cold climates.

When you install an HRV, YOU control the ventilation in  your energy efficent GreenLife home.
