10 Best Diy Mini Split 2026 in the United States

The Senville LETO Series Mini Split offers a strong cooling and heating capacity with 24,500 BTUs (2 tons), making it suitable for spaces up to about 1,250 square feet. It has a solid energy efficiency rating (SEER 17), which means it can save on electricity compared to less efficient models. This unit includes a heat pump that works effectively in cold weather down to 5°F (-15°C), so it can provide warmth through winter months, not just cooling in summer. Noise level is low at 34 dB, so it won’t be distracting in quiet rooms like bedrooms or offices. The system supports Alexa voice control and app integration, adding convenience for adjusting temperature remotely or setting routines.

It’s a single-zone system, meaning it cools and heats one area at a time. Installation requires professional help, but the package comes with all necessary parts including a 16-foot line set and communication cable. A 5-year warranty on parts and compressor offers good protection, although labor costs are not covered. On the downside, the product is not BEE Star Rated, which may be a consideration depending on local energy standards. Also, being a 220V system, it might need specific electrical setup in your home.

This mini-split is a stylish and versatile choice if you want an energy-efficient heating and cooling option that’s quiet, easy to control via smart devices, and capable of handling moderate-sized rooms.

The MRCOOL Easy Pro 12,000 BTU ductless mini-split heat pump is a solid choice for anyone looking to cool or heat a small to medium room, up to about 550 square feet. It offers a good balance of power and convenience, with 12,000 BTUs enough to handle typical living spaces or home offices. One of its biggest draws is the DIY-friendly installation, which tends to save time and money compared to professional setups. The unit operates quietly at around 43 decibels, so it won’t disturb your daily activities or sleep. It provides both heating and cooling, making it useful year-round.

The addition of smart WiFi control means you can easily adjust settings remotely via apps or voice assistants like Alexa or Google Assistant, which is a nice modern touch. The product has a 2-star energy efficiency rating, suggesting it may use more electricity than higher-rated models, potentially leading to higher energy bills. It is best suited for single-room use rather than whole-house solutions due to its likely single-zone setup and unspecified SEER rating.

If you want a straightforward, quiet, and smart mini-split for one area with a fairly simple installation process, this unit fits well. Just be aware of some energy efficiency trade-offs and the single-zone configuration.

The MRCOOL Easy Pro 24,000 BTU mini-split is designed as a user-friendly, all-in-one heating and cooling solution for spaces up to about 1,050 square feet. Its 24,000 BTU rating makes it powerful enough for medium-sized rooms or small homes. This model features a 5th generation DIY installation, which reduces the need for professional help and lowers installation costs—a big plus for those comfortable with basic home projects. Noise level is fairly low at 43 dB, so it should operate quietly without disturbing your daily activities. The unit offers both heating and cooling, providing comfort throughout the year. It also includes smart WiFi control compatible with Alexa and Google Assistant, allowing easy temperature adjustments from your phone or voice commands.

The product has a 2-star BEE rating, which suggests it might not be the most energy-saving option compared to higher-rated models. The unit supports only a single zone, making it best suited for cooling or heating one main area rather than multiple rooms. Its sleek, neutral design should blend well into most interiors, and the unit’s size is moderate at roughly 33 by 21 inches.

This MRCOOL mini-split represents a solid choice for DIY enthusiasts wanting a straightforward, quiet, and reasonably powerful system for a single-zone space, while those prioritizing top energy efficiency or multi-zone setups may want to explore other options.
