Zone Air® Airframe DUAL ZONE 24,000 BTU (12K+12K) 21 SEER2 230V Ceiling Cassette Mini-Split Heat Pump System with 2x Pre-Charged Linesets - Up to 1,200 Sq Ft

Two Hidden Ceiling Cassettes, One Condenser — Independent Comfort for Two Rooms, All DIY

The Zone Air Airframe dual-zone 24,000 BTU system pairs two recessed 12,000 BTU ceiling cassettes with a single outdoor condenser, so two separate rooms each get their own flush, low-profile cassette and their own independent temperature control. Both heads recess into the ceiling for a clean, architectural look with even 4-way airflow, and both connect with pre-charged line sets — so this two-room, professional-grade system is still a true DIY install that saves you $3,000–$5,000.

Each pre-charged line set comes with R-454B refrigerant for easy installation and stays factory-sealed from start to finish. You never handle refrigerant, you never need a vacuum pump, and EPA Section 608 certification requirements don't apply. With 12,000 BTU per zone, this system heats and cools up to 1,200 sq ft total — up to 600 sq ft in each of two zones — making it ideal for conditioning two bedrooms, a primary suite plus office, or a living room and den from one compact outdoor unit.

Because each cassette recesses up into the ceiling, this install goes a step beyond a wall unit: you'll need access above each room through a drop-ceiling tile or open joist bay and clearance in the cavity. But the refrigerant work is already done at the factory on both line sets. With basic tools, a drill, and the quick-connect fittings, most homeowners complete both zones over a weekend.

Why You'll Love It

• Independent Two-Zone Control — Each room gets its own recessed cassette and its own thermostat, so you can keep a bedroom cool while the office stays warm. One outdoor condenser serves both zones, cutting clutter outside while giving you full room-by-room control.
• Discreet 4-Way Airflow In Both Rooms — Both cassettes recess flush into the ceiling and distribute air in all four directions, blanketing each room evenly with no wall box and no wasted wall space — a clean architectural look in two rooms at once.
• Up to 21 SEER2 Efficiency — A higher SEER rating means lower bills, and at up to 21 SEER2 with Energy Star certification this dual-zone system runs efficiently across both rooms. Mini-splits can save up to 30% on energy costs versus traditional HVAC.
• Cold Climate Performance — Reliable heating down to -13°F with enhanced vapor injection that maintains approximately 85% of rated heating capacity at 5°F — both rooms stay comfortable through deep winter.
• 5-Year Warranty Protection — Zone Air backs the whole system with 5-year parts and 7-year compressor coverage plus a 45-day satisfaction guarantee — peace of mind across both zones on an install you did yourself.

What Makes It Different

Multi-zone ceiling cassette systems are almost always sold as pro-install jobs, with a technician vacuuming and charging every line. The Airframe dual-zone system is built around pre-charged, quick-connect line sets for both cassettes, so you get hidden ceiling comfort in two rooms without two contractor invoices.

• Pre-Charged Line Set Technology — Both line sets arrive factory-sealed with R-454B refrigerant. Hand-connect the quick-connect fittings on each, torque to spec, and both circuits are ready. No vacuum pump, no gauges, no HVAC license — pre-charged line sets eliminate the need for HVAC licensing entirely.
• True DIY for Two Zones — With two mounting frames, detailed instructions, and video support, recessing two cassettes is a homeowner job. You will need ceiling-cavity access above each room and basic tools — a drill, wrench set, and level — and the refrigerant work on both zones is already finished.
• Cold Climate Optimization — Standard multi-zone cassettes fade below freezing; Zone Air's Airframe uses enhanced vapor injection to sustain heat to -13°F in both rooms. This is a purpose-built cold climate heat pump, not an air conditioner with a reversing valve bolted on.

How It Works

1. Frame and Mount Both Cassettes — Open access above each room through a drop-ceiling tile or joist bay, secure each cassette into its opening with the included mounting frames, and set the single outdoor condenser on a pad or bracket. Route each pre-charged line set up through the ceiling and connect both cassettes to the condenser with the quick-connect fittings. Testing connections with soapy water is mandatory to check for leaks before activation, and proper torque and sealing are essential for leak prevention.
2. Power and Configure — Wire the condenser to a dedicated 208–230V circuit. A licensed electrician is recommended for the electrical disconnect box to ensure code compliance and safety. Once powered, configure each zone in the smartphone app in minutes and add voice control for both rooms.
3. Independent Comfort — Each cassette heats or cools its own room on its own schedule, distributing air evenly in four directions. Ductless, zoned comfort means no duct losses and no expensive ductwork — you condition only the rooms you are using, exactly how each one wants it.

Who It's For

Ideal for:

• Homeowners who need to condition two separate rooms independently from a single outdoor unit
• Two rooms in the 350–600 sq ft range each — paired bedrooms, a primary suite plus office, or a living room and den
• Spaces with a drop-ceiling or accessible joist bay above each room, where both cassettes can recess flush
• DIYers who want hidden, architectural ceiling comfort in two rooms while saving thousands on professional multi-zone installation

If you want independent, hidden-in-the-ceiling comfort in two rooms and an install you can complete yourself, the Airframe dual-zone 24,000 BTU system delivers. Energy-efficient mini-splits can qualify for rebates and tax credits — including up to $2,000 under the federal Section 25C tax credit for qualifying heat pumps — so a two-zone upgrade keeps paying back across years of use.
