Can I heat my garage and adjacent rooms with one system? Absolutely. Multi-zone systems connect up to eight indoor heads to a single outdoor unit, allowing you to heat your garage, workshop, bonus room, or even connect to your home’s existing system. Each zone operates independently, so you only heat occupied spaces. This scalability makes revolutionary ductless systems a whole-home solution that starts with your garage and grows with your needs.
