The answer to 'should I get zone control system or' is whether to install a zone control system or a traditional single-zone HVAC system depends on the size and layout of your home, your heating and cooling needs, and your budget. Zone control systems allow you to independently control the temperature in different areas or 'zones' of your home, which can improve comfort and energy efficiency. However, they also tend to be more expensive to install than a single-zone system.
Zone control systems are best suited for larger homes with multiple floors or distinct living areas that have different heating and cooling requirements. They use motorized dampers in the ductwork to direct airflow to the appropriate zones, and each zone has its own thermostat. This allows you to heat or cool only the areas that are in use, rather than the entire home. This can lead to significant energy savings, especially if certain rooms or floors are rarely used. Zone control systems are also beneficial for homes with rooms that receive more or less sunlight, or that have high ceilings or open floor plans that make it difficult to maintain a consistent temperature.
