Before diving into repairs, it’s crucial to understand how dual-zone systems work. Unlike single-zone systems that regulate the temperature of the entire house as a single unit, dual-zone systems use dampers and multiple thermostats to control airflow to different zones.

• Zones: A zone is a designated area within your home, such as the living room, bedrooms, or office. Each zone has its own thermostat that allows you to set a desired temperature.
• Dampers: Dampers are motorized valves located in the ductwork that control the flow of air to each zone. When a zone’s thermostat calls for heating or cooling, the dampers open or close to direct airflow accordingly.
• Thermostats: Each zone has its own thermostat. These thermostats communicate with the HVAC system’s control panel to regulate the temperature in their respective zones.
• Control Panel: The control panel is the "brain" of the dual-zone system. It receives signals from the thermostats, controls the dampers, and manages the operation of the furnace or air conditioner.
• Air Handler: The air handler is the unit that blows air through the ductwork. It may be part of your furnace or air conditioning unit.
