Senville is a mini split brand that sells complete ductless heating and cooling kits, meaning the indoor unit, outdoor unit and connecting line set come in one package. A mini split is an air conditioner split into two parts: a slim unit on your inside wall that blows air, and a compressor outside that moves heat in or out. Because no ducts are needed, it suits additions, garages, open living areas and older homes. Every model here is also a heat pump, which simply means it can run in reverse to warm a room in winter.
The three models differ in size and climate: the AURA and Elite are 18,000 BTU systems built for cold regions, with the Elite adding newer efficiency ratings and a longer warranty, while the LETO is a smaller 12,000 BTU unit that runs on 110 volts.

Senville AURA Mini Split Air Conditioner
Best for: Large rooms in very cold climates
Pros
- Heats down to -22°F
- Energy Star, UL and AHRI certified
- Works with Alexa
- 27 dB listed noise level
Cons
- Specs list 17,000 BTU cooling
- Professional installation required
The Senville AURA Mini Split Air Conditioner is sold as an 18,000 BTU heat pump. BTU stands for British Thermal Unit, a measure of how much heat a system can move in an hour; a bigger number means it can handle a bigger space. One detail to note: the listing title says 18,000 BTU, but the specification table lists cooling power at 17,000 BTU. That gap is small, but if you are sizing close to the limit, ask the seller which figure applies.
The AURA’s headline strength is winter performance. The listing says it delivers heating and cooling even in extreme conditions down to -22°F (-30°C). It uses a 208-230V DC inverter, a type of compressor that speeds up and slows down smoothly instead of switching fully on and off, which is how mini splits save energy and keep temperatures steady. It is Energy Star certified, UL Listed and AHRI Certified, uses R-454B refrigerant and has a listed noise level of 27 dB with a rated wattage of 1360 watts.
The kit includes the indoor air handler, the outdoor condenser, a 16 ft. line set and a communication wire. Alexa voice and app control let you change the temperature from anywhere and build routines. The listing is firm that professional installation is required and that this is not a DIY system. It suits a homeowner in a cold region who wants an 18,000 BTU class unit for a bedroom, living room, store or restaurant, but the Elite gives a fuller efficiency picture and a quieter rating.
Senville Elite Mini Split AC Heating for Efficiency and Quiet

Senville Elite Mini Split AC Heating
Best for: Quiet, efficient heating and cooling year-round
Pros
- 6 SEER2 and 15 EER2
- Covers about 750-1000 sq. ft
- 10-year compressor and parts warranty
- Quietest listed at 23 dB
Cons
- Heavy at 125 pounds
- Pro install needed for warranty
The Senville Elite Mini Split AC Heating system is the most thoroughly documented of the three. It is rated at 18,000 BTU in both its title and its specs, and it lists 25.6 SEER2 and 15 EER2. Those are efficiency scores: SEER2 measures cooling efficiency across a season, and EER2 measures it at a single hot condition. Higher numbers mean less electricity for the same comfort. The listing says the Elite is Energy Star certified and sized for roughly 750 to 1,000 square feet, which covers a large open living area or a small apartment.
Like the AURA, it heats down to -22°F (-30°C), so it can be a year-round system in cold-weather regions. It runs on 230 volts and lists 840 watts. Its noise rating of 23 dB is the lowest of the group, and the listing calls it whisper-quiet for bedrooms, offices and living spaces. Alexa voice control, app control, schedules and a wireless remote are all included, along with an Alexa USB kit.
The box includes the indoor unit, outdoor unit, remote and a 16 ft. installation kit that is pre-charged with refrigerant for runs up to 25 ft. The warranty is the strongest here: 10 years on the compressor and 10 years on parts, with professional installation required to keep that coverage. The complete system weighs 125 pounds, and the listed dimensions are 11 by 46.8 by 13.5 inches. This is the pick for most people shopping for a Senville mini split 18000 BTU unit who want efficiency, quiet and long warranty support. The AURA only makes more sense if it fits your installer’s plan better.
Senville LETO Mini Split Air Conditioner for Smaller Rooms

Senville LETO Mini Split Air Conditioner
Best for: Bedrooms and medium rooms on 110V
Pros
- 4-in-1 cooling, heat, dehumidify, fan
- 110-volt power
- Alexa enabled
- Refrigerant pre-loaded for 25 ft
Cons
- Heat pump rated only to 5°F
- 12,000 BTU, not for large spaces
The Senville LETO Mini Split Air Conditioner is the smaller option at 12,000 BTU. It is worth a look if your room is not as large as you first thought, because an oversized unit can cool too quickly and switch off before removing humidity. The LETO runs on 110 volts, the same kind of standard household circuit voltage many homes already use, although a mini split still needs a proper dedicated circuit set up by a pro.
The listing calls it a 4-in-1 system: air conditioning, heat pump, dehumidifier and fan, plus a turbo function for a quick boost. Its heat pump is rated to work down to 5°F (-15°C), which is milder than the -22°F of the AURA and Elite. It uses a DC inverter, R-454B refrigerant, is UL Listed and AHRI Certified, lists 28 dB of noise and 1020 watts, and works with Alexa for voice or app control.
The installation package includes the indoor air handler, outdoor condenser, remote, and a 16 ft. line set with communication wire, pre-loaded with refrigerant for up to 25 ft. Professional installation is required. The warranty covers 5 years on parts and 5 years on the compressor, labor not included, and Senville offers free technical assistance. The LETO suits a bedroom, office or medium living area in a region with moderate winters. For large rooms or harsh cold, step up to the Elite.
How to Choose the Right Senville Mini Split Air Conditioner
Size comes first. The Elite’s listing gives a coverage range of about 750 to 1,000 square feet at 18,000 BTU, which is a helpful reference point. A 12,000 BTU unit like the LETO is meant for a smaller space. Ceiling height, sun exposure and insulation all change the real need, so an installer’s load calculation is the most reliable guide for a ductless mini split for a large room. If you want to compare before deciding, see our other ductless mini split roundup.
Next, consider your winters. If temperatures regularly drop well below freezing, the AURA and Elite are rated to -22°F. The LETO’s heat pump is rated to 5°F, so in colder regions it may work best alongside another heat source.
Check your electrical setup. The AURA uses 208-230V and the Elite 230V, while the LETO runs on 110V. Your electrician will confirm what your panel can support, and a pro will also handle the refrigerant lines and vacuum the system before it runs.
Warranty and noise may tip the decision. The Elite offers 10 years on compressor and parts and the lowest listed noise at 23 dB. The LETO offers 5 years on each. The AURA listing does not specify its warranty, so ask before you buy. Shoppers still weighing brands can read this guide to another popular mini split line.
