However, one thing that puts buyers away is its premium pricing. For more cost effective options, see other top heating options in the 6 Best Mini Splits for Heating in 2025 post.

- BTU: 12,000
- SEER: 22.5

MrCool is a brand that puts DIY first. They have the most comprehensive guides (manuals, videos, customer supports, etc.) on DIY installation. A licensed HVAC contractor is not required for warranty on the DIY series units as per MrCool’s warranty documents.
However, the DIY series is more costly to purchase. For more budget-friendly options, see other DIY models in the 5 Best DIY Mini Splits in 2025 post.
Smartest Mini Split: LG Art Cool Premier 9K
- BTU: 9,000
- SEER: 27.5

Among the smartest mini split in 2025, the LG Art Cool Premier 9K stand out as the best unit for smart home integration due to LG’s network effect with its ThinQ app and hundreds of other home appliances. Within the same app, multiple appliances can be controlled, including LG’s mini splits.
Smart home is about the seamless integration between appliances. LG is advantageous because they have many home appliances aside from air conditioners. This makes real-world experience much better than other mini splits.
However, this series is costly and it requires other LG appliances for network effect. Those who are not in the LG ecosystem see other smart choices in the 5 Smartest Mini Splits in 2025 post.

- BTU: 12,000

Most mini splits are fairly quiet but the quietest among them all goes to the Daikin ENTRA Series 12K. Its Quiet Mode produces only 19 dB indoors and the outdoor unit is whisper-quiet at 48 dB, quieter than most other outdoor units of the same class.
What more impressive is its outdoor noise at higher BTU. The 24K BTU unit produces 52 dB outdoors which is applaudable, given other budget units at 58 to 60 dB. A mere 8 dB difference translates to more than 2 times quieter, which the difference is very noticeable in real life.
However, the ENTRA series is Daikin’s low-end models and therefore, the energy efficiency is low. For other quiet mini splits with higher efficiency, see the 5 Quietest Mini Splits in 2025 post.

- SEER: 21.3

With the affordable pricing, it is a low-cost option for those who are looking for the best mini split for the money, prioritizing simplicity over features.
Key Considerations for Choosing a Mini Split
Choosing the right mini split is as important as knowing which mini split is the best. With the right application only then you can harness the full potential of it.
- Sizing: Space size dictates BTU needs. A 9,000 BTU unit suits ~400 square feet. Larger spaces need 24,000 BTU.
- Climate: Climate shapes efficiency. High SEER (>25) optimizes cooling in warm areas. High HSPF ensures low-cost heating in cold climates.
- Noise: Noise affects comfort. Below 30 dB fits quiet bedrooms and around 40 dB suits garages.
- Wi-Fi Control: Wi-Fi offers automation, ideal for tech users. Basic remotes provide simplicity.
- DIY kits: DIY kits suit hands-on users. Pro setups ensure precision for complex systems.
- Reliability: Durability reduces maintenance. Trusted brands last longer. R-32 refrigerants align with sustainability. Rugged builds suit harsh environments like garages.
- Lifestyle: Consider lifestyle. Tech-driven homes benefit from automation, while simple setups favor basic controls, ensuring a tailored choice.
How Mini Splits Work: A Quick Primer
Mini splits cool and heat homes without bulky ductwork (ducted mini splits are available), making them ideal for apartments, living rooms, offices, or garages.
An indoor unit, mounted on a wall or ceiling, delivers air directly to a room, like a bedroom or living space. It connects to an outdoor unit via thin refrigerant lines, which carry a cooling or heating fluid. This setup allows precise temperature control for each room, saving energy compared to traditional systems.
In cooling mode, the indoor unit pulls warm air from the room, passing it over a cold coil to absorb heat, then blows cool air back out. The outdoor unit releases this heat, keeping your space comfortable. For heating, the process reverses: the outdoor unit extracts warmth from outside air, even at -22°F, and sends it indoors.
Mini splits are perfect for living spaces converted from garages, as noted in my 5 best mini split for garages in 2025 post. Smart controls, like Wi-Fi apps, let you adjust settings remotely, saving energy. DIY kits simplify setup for hands-on users while pros ensure reliability.
Modern mini splits use eco-friendly refrigerants like R-32, reducing environmental impact, a 2025 trend. Quiet designs, as low as 19 dB, suit bedrooms. From small studios to rugged workshops, mini splits adapt to any home with tailored comfort.
