What is a Dual-Zone HVAC System? Emergency Heating Repair Near Me Emergency Air Conditioner Repair Near Me Same Day Hvac Repair Heating Cooling Repair
Before diving into repairs, let’s clarify what a dual-zone HVAC system is. In a single-zone system, one thermostat controls the temperature for the entire house. A dual-zone system, on the other hand, divides your home into two distinct zones, each with its own thermostat. This allows you to set different temperatures in, for example, the upstairs and downstairs, or the living area and the bedrooms. 24 Hour Emergency Heating Service Ac Emergency Repair Near Me Weekend Ac Repair Emergency Hvac Service Near Me
Dual-zone systems typically use dampers within the ductwork to control airflow to each zone. These dampers are motorized and respond to the thermostat settings in each zone. When a zone needs heating or cooling, the damper opens to allow airflow. When the desired temperature is reached, the damper closes to restrict airflow.
