Choosing a ductless mini-split air conditioner and heat pump means matching cooling and heating capacity to your room size, voltage, and smart-feature wants. These four units span the low- to high-capacity end of the category, with listed prices from USD 458.16 to USD 1,249.99. The decision usually comes down to how many BTUs you need and whether you want a 110V or 220V system.
Quick Take
If you want the lowest listed price, the Confortotal 12,000 BTU unit is the entry point. If your room is larger and 220V is available, the Confortotal 18,000 BTU unit adds coverage. The Senville 24,000 BTU LETO is the biggest option, and the Senville 12,000 BTU unit is the 110V model with a 21 SEER2 rating.

Confortotal 12,000 BTU Ductless Mini Split (110V, WiFi)

The Confortotal 12,000 BTU system is the lowest listed price at $458.16. It cools and heats a listed 551-600 sq ft, runs on 110V, and adds WiFi capability. The included installation kit and R32 refrigerant round out the package. Its limitation is the coverage ceiling: at 12,000 BTU, it is the smaller-capacity option in this group and is not designed for large open areas. If your space fits within the listed range, this is a direct way to get a ductless heat pump without moving up in price.
Confortotal 18,000 BTU Ductless Mini Split (220V, WiFi)

The Confortotal 18,000 BTU model lists coverage of 851-900 sq ft and uses a Toshiba compressor. Its 220V design makes it a better fit for locations where 220V is part of the setup, and the system adds WiFi compatibility with Alexa plus a full installation kit. The 18,000 BTU capacity splits the difference between the 12,000 BTU models and the 24,000 BTU Senville LETO, which helps when you need more than 600 sq ft but not the largest unit. One limitation is that it is listed as not Energy Star compliant, so if strict energy certification is a priority, one of the SEER2-rated units in this group may be a better match.
Senville LETO 24,000 BTU Ductless Mini Split

The Senville LETO 24,000 BTU model is the most expensive of the four at USD 1,249.99, but it is also the largest, with 24,000 BTU cooling, 25,000-29,999 BTU heating, and coverage up to 1,250 sq ft. It is rated 18.7 SEER2, can heat down to 5°F, and includes Alexa-enabled smart control and a 27 dB indoor unit. The limitation is matched to its scale: for a bedroom or small office, a 12,000 BTU unit will fit the space better and carry a lower listed price.
Senville 12,000 BTU Ductless Mini Split (110V, 21 SEER2)

The Senville 12,000 BTU model pairs 110V operation with a 21 SEER2 rating and a variable-speed blower. Its listed coverage is up to 700 sq ft, and it includes Wi-Fi and Alexa compatibility. At USD 799.99, it sits above the 12,000 BTU Confortotal in listed price, so the main trade-off is paying more for the higher SEER2 figure. That combination makes it a natural fit for bedrooms, home offices, and similar small-to-medium rooms where the 110V format is convenient. If efficiency is your priority, this is the 12,000 BTU option with the 21 SEER2 rating to choose.
Final Recommendation by Use Case
- Lowest listed price and a 110V 12,000 BTU setup: Confortotal 12,000 BTU Mini Split.
- 110V operation with a 21 SEER2 rating: Senville 12,000 BTU Mini Split.
- 220V setup for around 900 sq ft: Confortotal 18,000 BTU Mini Split.

Start with the room size and available voltage, then match that to the listed BTU and coverage figures. If the listed price is the deciding factor and 12,000 BTU is enough, the Confortotal 12,000 BTU is the clearest pick. If the largest possible space is the goal, the Senville LETO 24,000 BTU is the answer.
