Multi-Zone Systems



There is no need to heat and cool every room in your home all year long, when you only occupy a few rooms at a time. Instead, achieve total comfort on demand while saving money and reducing your energy bills with a zoned solution from Formula Fabrication.
A zoned home is divided into segments based on each area’s need for conditioning. Rather than relying on a single unit to cool or heat the entire property, multi-zoned homes utilize a network of small, energy efficient units and thermostats to send the right amount of conditioned air to each zone. This allows homeowners to have room-by-room control.
