What is a zone system?
Zoning Systems separate your home’s duct work into different comfort areas, allowing for independent temperature control in distinct areas that require specific temperature conditioning.
For example, a cathedral-style room with large bay windows may retain too much heat in the summer and feel too cold in the winter. A Zoning System will deliver more conditioned air to this large, sun-drenched area to help compensate for the heat gained or lost through the windows. A different example of areas that might benefit from Zoning might be a nursery, home theater or music studio, where different temperatures may be needed in each room for the comfort and enjoyment of the people occupying these rooms. Contemporary families have different lifestyles and comfort needs. You could have a home office that needs extra conditioning during the day and none at night. Or you only use the upstairs or back bedrooms when guests visit. Whatever your needs, a zoning system can maintain each area of your house at the perfect temperature for you and each family member.
