Energy Recovery Ventilation (ERV) System Included
Because Clean Air Should Be Standard.
Energy Recovery Ventilation is standard on The Haven. The system continuously exhausts stale indoor air and brings in fresh, filtered outdoor air while recovering heat and humidity — a core requirement of any modern healthy home, and one of the single biggest contributors to indoor air quality. Benefits include cleaner indoor air, reduced indoor pollutants, better humidity control, improved comfort, reduced allergens, and a healthier living environment.
