Zone Air® Airframe DUAL ZONE 19,000 BTU (9.5K+9.5K) 21 SEER2 230V Ceiling Cassette Mini-Split Heat Pump System with 2x Pre-Charged Linesets - Up to 950 Sq Ft

Two Flush Ceiling Cassettes for Two Rooms — Independent, Discreet, and DIY-Installable

The Zone Air Airframe dual-zone 19,000 BTU system connects two recessed 9,500 BTU ceiling cassettes to one outdoor condenser, giving two rooms their own flush, hidden 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 system installs DIY and saves you $3,000–$5,000 over a professional job.

Each pre-charged line set comes with R-454B refrigerant for easy installation and stays factory-sealed throughout. You never handle refrigerant, you never need a vacuum pump, and EPA Section 608 certification requirements don't apply. At 9,500 BTU per zone, this system heats and cools up to 950 sq ft total — up to 475 sq ft in each of two zones — making it a great fit for two bedrooms, an office and a guest room, or any pair of moderate rooms you want to condition independently.

Each cassette recesses up into the ceiling, so this install is 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 on both line sets is finished at the factory. 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 one room can run cool while the other runs warm. A single outdoor condenser serves both zones, keeping the exterior tidy while you control each room separately.
• Discreet 4-Way Airflow In Both Rooms — Both cassettes mount flush in the ceiling and push air in all four directions for even comfort with no wall box and no lost wall space — a clean, finished look in two rooms at once.
• Up to 21 SEER2 Efficiency — A higher SEER rating means lower energy bills. At up to 21 SEER2 with Energy Star certification, this dual-zone system runs efficiently in both rooms, and mini-splits can save up to 30% on energy costs versus traditional HVAC.
• Cold Climate Performance — Reliable heating down to -13°F thanks to enhanced vapor injection, which holds approximately 85% of rated heating capacity at 5°F. Both rooms stay comfortable through the coldest months.
• 5-Year Warranty Protection — Zone Air covers the full system with 5-year parts and 7-year compressor protection plus a 45-day satisfaction guarantee — peace of mind across both zones on an install you handled yourself.

What Makes It Different

Two-zone ceiling cassette systems are almost always pitched as pro-install equipment, with a technician vacuuming and charging each line. The Airframe dual-zone 19K is built around pre-charged, quick-connect line sets for both cassettes, so hidden ceiling comfort in two rooms no longer requires a contractor.

• 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 — Two mounting frames, step-by-step instructions, and video support make recessing two cassettes 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 done.
• Cold Climate Optimization — Standard two-zone cassettes lose output 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, set up 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, sending air evenly to all four corners. Ductless, zoned comfort eliminates duct losses and expensive ductwork — you condition only the rooms in use, each at its own setting.

Who It's For

Ideal for:

• Homeowners who want to condition two moderate rooms independently from one outdoor unit
• Two rooms in the 350–475 sq ft range each — paired bedrooms, an office and guest room, or two finished spaces
• 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 moderate rooms and an install you can complete yourself, the Airframe dual-zone 19,000 BTU system fits. 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 the two-zone upgrade keeps paying back across years of use.
