How much space can a 4-zone system cover?

With outputs between 36,000–48,000 BTU, a quad-zone mini split can cover 1,200–2,000 sq ft. Perfect for bedrooms, offices, or living areas needing zone-specific control. Try our free “Size-My-Room” tool at MiniSplits4Less.com.

What are the benefits of 4-zone mini splits?

One outdoor unit reduces exterior clutter and installation costs. Each zone has its own thermostat, maximizing comfort and efficiency. Cooper & Hunter supports wall, ducted, or cassette heads, Wi-Fi smart control, and cold-climate heating down to –22°F.
