The answer to 'which is better zone control system or' is that a zone control system is generally better for most homes compared to a single-zone HVAC system. Zone control systems allow you to independently control the temperature in different areas or 'zones' of your home, providing more customized comfort and energy savings.
With a zone control system, you can set different temperatures for different rooms or floors based on your family's preferences and usage patterns. This can help you avoid heating or cooling empty rooms, reduce hot and cold spots, and optimize energy usage. Zone control is especially beneficial for homes with multiple levels, irregular layouts, or rooms that get more or less sun exposure.
