About Aprilaire Zoning System
AprilAire Zone Control Systems use smart panels, thermostats, and gearless dampers to create 2-12 customizable zones, ensuring even temperatures throughout multi-level or sprawling homes. By opening dampers only in calling zones and using methods like Controlled Pressure Relief (CPR), they deliver 85%+ design airflow efficiency without bypass waste, supporting multi-stage heat pumps, humidifiers, and ventilation for optimal IAQ and savings up to 30%.
