Zone Air® Airframe 3 ZONE 36,000 BTU (12K+12K+12K) 24 SEER2 230V Ceiling Cassette Mini-Split Heat Pump System with 3x Pre-Charged Linesets - Up to 1,800 Sq Ft

Three Zones of Invisible, 360° Comfort — Flush in the Ceiling

This 3 zone ceiling cassette mini split conditions three separate spaces — up to 1,800 square feet total — with nothing on the walls. Each 12,000 BTU Airframe cassette recesses flush into the ceiling and washes air in four directions at once, covering rooms evenly from the center instead of blowing from one wall. Every zone has its own thermostat, remote, and WiFi control.

All three linesets ship pre-charged with R454B refrigerant, so there is no vacuum pump, no gauges, and no EPA license in the install. The 27,000 BTU multi-zone condenser is rated 24 SEER2 with heating to -13°F, and integrated condensate pumps in each cassette handle drainage without gravity runs.

Why You'll Love It

• 360° Air Distribution — Four-way discharge from the center of the ceiling covers a room far more evenly than a wall unit blowing from one side — no hot corners, no drafts across the couch.
• Completely Out of the Way — Cassettes sit flush in a drop ceiling or between joists. Walls stay clear for shelving, art, and sight lines — ideal for offices, restaurants, retail, and open-concept homes.
• Three Independent Zones — Each cassette runs its own schedule and setpoint. Condition the conference room, showroom, and back office separately instead of arguing over one thermostat.
• DIY-Friendly Multi-Zone — Three pre-charged quick-connect linesets mean the refrigerant circuit never opens. Cassette installs need ceiling access and a second set of hands, but no HVAC technician.
• 24 SEER2 With Cold Climate Heat — The inverter condenser is rated 24 SEER2 and 10.5 HSPF2 and keeps heating down to -13°F.

What Makes It Different

Ceiling cassette multi-zone systems are usually contractor-only equipment: flared fittings, vacuum pulls on every circuit, and a refrigerant charge calculation per zone.

• Pre-Charged, Quick-Connect Circuits — Each of the three linesets arrives factory-sealed with refrigerant inside. Thread the couplings by hand, torque to spec, and verify with soapy water.
• Honest Capacity Numbers — Three 12K cassettes connect 36,000 BTU/h of indoor capacity to a 27,000 BTU/h rated condenser — a standard multi-zone connection ratio, and both numbers are printed in the spec table below.
• Built-In Condensate Pumps — Every cassette includes an integrated condensate pump, so drainage routes up and over to wherever it needs to go — no gravity drain planning.

How It Works

1. Frame and Hang Three Cassettes — Cut the ceiling openings, hang each cassette from the structure above, and clip on the flush trim panels.
2. Run and Connect the Linesets — Route the three pre-charged linesets through the ceiling to the outdoor unit, hand-thread the quick-connect couplings, torque to spec, and test each joint with soapy water.
3. Power and Pair — Wire the condenser to a dedicated 230V circuit (a licensed electrician is recommended for the disconnect), then pair each zone to the WiFi app.

Who It's For

This 3 zone cassette system is for:

• Offices, restaurants, and retail spaces that need three independently controlled areas with nothing on the walls
• Open-concept homes and finished basements with drop ceilings or accessible joist bays
• Renovations where wall units would clash with the design
• Building owners who want commercial-style comfort without a commercial installation contract

Only need two zones in the ceiling? The Airframe dual-zone cassette system covers two rooms.
