How a Heat Recovery Ventilator Works

• Removes Stale Air: Pulls stale, trapped air out of your home to reduce stuffiness and odors.
• Introduces Fresh Air: Brings in filtered outdoor air to improve overall indoor air quality.
• Recovers Heat: Transfers warmth from the outgoing air to the incoming fresh air, helping maintain comfort while reducing energy loss.

This gives you continuous fresh air without the discomfort of opening windows in winter.

Why Wisconsin Homes Benefit from an HRV

Modern, energy-efficient homes with tightly sealed construction, spray-foam insulation, and new windows often trap air indoors, leading to stale conditions and poor air circulation. Homes with attached garages can also experience fumes, odors, and other airborne contaminants entering the living space.

In cold Wisconsin winters, bringing in fresh air without pulling in freezing outdoor temperatures is essential for comfort and efficiency. An HRV also helps manage excess moisture and reduce winter condensation that can contribute to mold and indoor air quality issues.
