Choosing between ductless mini split air conditioners and heat pumps can feel like a math problem: you need enough BTU for the room, the right voltage for your wiring, and an efficiency rating that balances upfront cost against long-term comfort. These four ductless systems all combine cooling and heating in one wall-mounted unit, but they split into two groups: 12,000 BTU models for spaces around 750 square feet, and 17,000-18,000 BTU units for larger areas up to about 1,250 square feet.
Quick take
If you need the largest capacity in this lineup, the 18000 BTU Mini Split Air Conditioner & Heater Pump System 19 SEER2 Ductless 230V is the most expensive at USD 526.35 and covers up to 1,250 sq ft. If you want the lowest listed price for a smaller room, the 12000 BTU 19 SEER2 Mini Split Air Conditioner & Heater Quiet, Efficient Comfort comes in at USD 349.99 and is rated for 701-750 sq ft. The 17000 BTU Mini Split Air Conditioner & Heater 230V WiFi, 20 SEER, ETL Certified sits between them at USD 509.98, and the 12000 BTU 22 SEER2 Mini Split Air Conditioner Heat Pump Inverter WiFi AC 110V offers the highest SEER rating in the group at USD 399.99.

Product notes
12000 BTU 19 SEER2 Mini Split Air Conditioner & Heater Quiet, Efficient Comfort
This is the entry point of the group. It covers 701-750 sq ft, and the product description emphasizes a quiet 42 dB indoor noise level, which makes it a sensible match for bedrooms and offices. It includes four operation modes: Cool, Heat, Dry, and Fan. The limitation is that the title does not list WiFi or app control, so you will likely be making adjustments with the included remote rather than from a phone.
12000 BTU 22 SEER2 Mini Split Air Conditioner Heat Pump Inverter WiFi AC 110V
This unit stands out for its 22 SEER2 rating, the highest efficiency number among these four systems. It is also the only one here with 110V in the title, which can be a better fit for spaces without 230V wiring. It covers 701-750 sq ft and includes WiFi, app control, and remote control. The limitation is that it is a 12,000 BTU system, so it is not designed for the larger 1,250 sq ft spaces that the 17,000 and 18,000 BTU models target.
17000 BTU Mini Split Air Conditioner & Heater 230V WiFi, 20 SEER, ETL Certified
The Garvee 17000 BTU Mini Split is the mid-capacity choice for larger rooms, with coverage described as up to 1,250 sq ft. Its 20 SEER rating is higher than the 19 SEER2 figures on the two non-22 SEER models in this set, and the title lists WiFi plus ETL certification. On the limitation side, it runs on 230V, so it will not suit a standard 110V outlet, and its listed price leaves little room below the larger 18,000 BTU system.
18000 BTU Mini Split Air Conditioner & Heater Pump System 19 SEER2 Ductless 230V
This is the biggest capacity in the lineup at 18,000 BTU, and the description says it covers rooms up to 1,250 sq ft. It runs on 230V and includes WiFi, remote control, and app control. The title also lists a 19 SEER2 rating. The limitation is that it carries the highest listed price in this comparison, so it makes the most sense if you need the extra capacity for a large area.
Final recommendation by use case
If your priority is keeping the purchase price low, the 12000 BTU 19 SEER2 Quiet, Efficient Comfort is the straightforward pick for a small room. If you need a 110V system with WiFi and the highest SEER rating, the 12000 BTU 22 SEER2 Mini Split is the natural match. For a large open area with 230V wiring and you want WiFi plus a certified unit, the Garvee 17000 BTU Mini Split covers up to 1,250 sq ft with 20 SEER. And if maximum capacity is the priority, the 18000 BTU Mini Split with a 19 SEER2 rating and app control delivers the most BTU in this set.
