Mini Split 12,000 BTU Gree Vireo 23 SEER2 WiFi Heat Pump Ceiling Cassette System VIR12HP230V1R32AO, CAS12HP230V1R32AH
The one-ton point in Gree's R32 cassette lineup, this system matches the VIR12HP230V1R32AO Vireo condenser to the CAS12HP230V1R32AH 360° cassette and includes the GREETF05 grille, both controllers, and factory WiFi. It holds a full 12,000 BTU/h of rated cooling and 12,000 BTU/h of rated heating at 23 SEER2, and it is the size most contractors reach for when a single room has outgrown a 9K head but does not yet justify moving up to 18K. The cassette shares the compact 22-inch cabinet of the 9K unit, so it drops into the same ceiling opening while carrying about a third more capacity.
Is a 12,000 BTU Ceiling Cassette System the Right Size?
Twelve thousand BTU generally covers something in the range of 400 to 550 square feet as a starting point. It is the workhorse capacity for a master bedroom, a two-person office, a small conference room, or a studio apartment where the cassette can sit centered in the ceiling and serve the whole footprint from one location.
Where this size earns its keep is partial-load performance. The inverter compressor throttles down to about 2,300 BTU/h of cooling, so on a mild spring afternoon the system idles quietly rather than short-cycling. That wide turndown also means a 12K cassette in a 450 square foot room usually runs at low fan speed most of the day, holding a steadier temperature and pulling more moisture out of the air than an oversized unit that satisfies the thermostat in short bursts. Room shape, ceiling height, door traffic, and glazing all shift the final selection.
Ideal for: Master bedrooms, two-person offices, small conference and training rooms, studio apartments, physical therapy rooms, tasting rooms, and finished basements in the 400 to 550 square foot range.
Need more capacity? Step up to the 18,000 BTU Gree Vireo 21 SEER2 Ceiling Cassette System for open living areas and larger commercial rooms. Comparing options? Browse the full 6K - 12K BTU single zone high-efficiency selection.
Recommended room sizes are general guidelines only. Actual system requirements depend on insulation, ceiling height, window area, ambient conditions, occupancy, and internal heat loads. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Note the line set detail on this pairing: the cassette carries a 3/8 inch gas connection while the VIR12HP230V1R32AO service valve is 1/2 inch, so plan the reducing fitting into the material list before the truck rolls. Everything else is accounted for — the GREETF05 grille, the wireless remote, the XE72-44/E wired controller, and the WiFi radio are all part of the system as shipped.

Frequently Asked Questions
How much space will the 12,000 BTU cassette system heat and cool?
Roughly 400 to 550 square feet as a general planning figure. A load calculation accounting for glazing, insulation, ceiling height, and occupancy gives the accurate answer for your specific room.
What is the practical difference between this 12K system and the 9K version?
Both use the same cassette cabinet and the same GREETF05 grille, so the ceiling work is identical. The 12K carries 12,000 BTU/h of rated cooling versus 9,100, and it holds 10,000 BTU/h of heating at 5°F where the 9K produces 7,600. The 9K is the more efficient of the two at 24 SEER2 against 23.
What refrigerant line sizes does this pairing use?
The cassette uses 1/4 inch liquid and 3/8 inch gas connections, while the VIR12HP230V1R32AO condenser is 1/4 inch liquid and 1/2 inch gas. Plan for a reducing fitting on the gas line. Total run is 10 to 66 feet with a 40 foot maximum elevation change.
Does the 12K cassette handle condensate on its own?
Yes. An internal condensate drain pump with a Sentry float switch is built into the CAS12HP230V1R32AH, so the unit can lift condensate above the ceiling to reach a drain without an external pump kit.
How quiet is the CAS12HP230V1R32AH indoors?
The cassette is rated 29 to 41 dB(A) from low to high fan speed. At the low end that is comparable to a quiet library, which is why this size is common in bedrooms and small conference rooms.
Is the GREETF05 grille the same panel used on the 9K cassette?
Yes. Gree uses the GREETF05 decorative grille across the 9K, 12K and 18K cassettes in this R32 line, and it is included with this system.
