10 Best Mini Split Units 2026 in the United States

The MRCOOL 36,000 BTU 5th Gen DIY Mini Split is a strong choice for cooling and heating spaces up to about 1,550 square feet, making it suitable for larger rooms, offices, or small commercial areas. Its 18 SEER rating indicates good energy efficiency, which helps reduce electricity bills during use. The noise level of 46 decibels is fairly quiet, so it won't be disruptive in a home or office environment. This model supports one zone, meaning it controls temperature in a single area rather than multiple separate rooms. A major plus is the easy DIY installation with pre-charged, quick-connect line sets that don’t require professional skills or special tools, saving money on setup. It also comes with smart controls compatible with Alexa and Google Assistant, making temperature adjustments convenient.

The unit combines cooling, heating, and dehumidifying features, so it works year-round and improves indoor comfort. It operates on 230 volts and is fairly heavy at 180 pounds, which might require some help during installation. The product offers a solid warranty (5 years parts, 7 years compressor), adding peace of mind. If you want a user-friendly, energy-smart mini split with strong capacity and easy setup for a single zone, this MRCOOL model fits well. However, if you need multi-zone control, you might want to explore other options.

The Senville LETO Series Mini Split is a solid choice if you need a 2-ton (24,500 BTU) unit capable of cooling or heating spaces up to around 1,250 square feet. Its SEER rating of 17 is respectable, meaning it’s fairly energy-efficient for year-round use, complemented by an inverter compressor that adjusts power use to save energy. The heat pump function works efficiently down to about 5°F, so it can provide heat in moderately cold climates. Noise level is quite low at 34 dB, which should keep your environment quiet and comfortable. This model supports one zone, so it’s best suited for single-room or open-plan areas rather than multiple zones.

Installation includes all necessary components and refrigerant for up to 25 feet of piping, but professional installation is required and labor costs are extra. The unit integrates with Alexa for convenient voice control and remote app access, a nice modern feature that can enhance ease of use. One downside is that the product is rated below some energy star standards and is imported from China, which may concern buyers focused on certification or support. The 5-year warranty on the compressor and parts offers good peace of mind, though labor isn't covered.

This mini-split fits well for homeowners or small businesses looking for a powerful, quiet, and smart-controlled system primarily for a single zone.

The MRCOOL Easy Pro 24,000 BTU mini-split unit is a solid choice for heating and cooling a space up to about 1,050 square feet. Its 24,000 BTU capacity should provide reliable comfort for medium-sized rooms or small homes. One of its biggest advantages is the easy DIY installation, which can save you money on professional setup and reduce hassle. This unit also operates quietly at 43 decibels, making it suitable for bedrooms or living areas where low noise is important. It offers both heating and cooling year-round, controlled conveniently through WiFi and compatible with voice assistants like Google and Alexa, which adds a modern touch and ease of use.

The product has a 2-star BEE rating, indicating it may consume more power compared to other mini-splits with higher energy efficiency ratings. It supports only a single zone, so it is best suited for one main area rather than multiple rooms. Maintenance and running costs should be reasonable due to the inverter technology.

This MRCOOL model is ideal if you want a quiet, easy-to-install, and smart-controlled mini-split for a single zone, although it may not be the most energy-efficient option available.
