Honeywell Energy-Efficient Ventilation Systems
Why do you need a Heat Recovery Ventilator?
In this midwest climate, homes are built very tightly and well insulated. Because of this during the winter months the stale air in our homes needs to be "exchanged" with fresh air from the outside. Every home new and old should have some type of ventilation system to bring in fresh air and exhaust old stale air.

Reduce window condensation with a Heat Recovery Ventilator. This will cut down on mold and mildew build-up along window sills.
