10 Best Mini Split Heat Pumps 2025 in the United States

The Senville LETO Series Mini Split is a solid choice if you want an efficient and quiet heating and cooling system for spaces up to around 1,250 square feet. With a cooling capacity of 24,500 BTU (2 tons), it can handle medium to larger rooms comfortably. Its SEER rating of 17 is quite good, meaning it uses electricity efficiently to keep your energy bills reasonable. The unit’s heat pump works well even in cold climates down to 5°F, which is useful if you live in cooler areas. It includes inverter technology, which helps maintain consistent temperatures while consuming less energy and reducing wear on the compressor. The noise level is low at 34 dB, so it will run quietly without disturbing your daily life.

This model supports only a single zone, so it’s best for one main living area rather than multiple rooms. One standout feature is Alexa compatibility, letting you control the system by voice or app, which adds convenience. The 4-in-1 functionality means it can cool, heat, dehumidify, and circulate air, making it a versatile option year-round. Installation requires professional help and the package comes with necessary parts and a 16-foot line set pre-charged with refrigerant. The design is sleek and unobtrusive, fitting well in homes or small businesses.

Warranty coverage is strong, with five years on parts and compressor. If you need to cool or heat multiple zones independently or want a higher efficiency rating, this might not be the best fit. Also, labor for installation is not included, so factor in extra cost there.
