The mrcool comfort made simple mrcool DIY select 12k btu 115v mini split offers easy installation via pre-charged quick connects and runs on standard 115V outlets. It covers 550 square feet with 12,000 BTU of cooling and heating capacity. Its 17.5 SEER2 rating and quiet 17.5 dB(A) operation make it a practical choice for bedrooms and small offices. Smart control through an app or voice assistants adds convenience for modern homes.
However, you might prefer a different unit if you need higher efficiency, a different size, or lack smart features. Some buyers prioritize raw cooling power over DIY installation ease. Others want a smaller footprint or a lower price point. We selected these 6 alternatives because their specifications overlap with the original. Each option shares the 115V voltage requirement and similar BTU ranges. This list helps you find a mini split that matches your specific room dimensions and feature needs without compromising on core performance.
How each alternative compares
Senville LETO 9000 BTU 115V
The Senville LETO 9000 BTU runs on 115V power like the MrCool, but it delivers less cooling capacity. It covers smaller spaces, making it better for compact rooms rather than larger areas. You get smart control features, similar to the MrCool app, but the lower BTU output means it cannot heat or cool as large a volume. It is a solid choice if you need a smaller unit that fits standard outlets. You sacrifice some raw power for a more compact footprint and lower energy draw in tight spaces.
Albott 9100 BTU 115V Mini Split
The Albott 9100 BTU offers higher efficiency with a 20.5 SEER2 rating, beating the MrCool’s 17.5 SEER2. It runs on 115V and includes smart remote control. This model is better if you prioritize energy savings over maximum cooling power. You get a more efficient system for smaller rooms, but you lose some raw cooling capacity compared to the 12,000 BTU MrCool. It suits buyers who want lower running costs and app control in a smaller space. You trade some cooling strength for better seasonal efficiency.
Rellytech 12,000 BTU 115V Mini Split
The Rellytech 12,000 BTU matches the MrCool’s cooling capacity and runs on 115V, but it offers a higher 19 SEER2 efficiency rating. This makes it better for energy-conscious users who want certified efficiency without sacrificing cooling power. You give up the pre-charged DIY quick connect system, so professional installation is required. It is a better choice if you want higher efficiency and quiet operation in a standard room. You trade DIY ease for better seasonal performance and steady inverter operation.
COSTWAY Blast Pro 12000 BTU
The COSTWAY Blast Pro 12,000 BTU provides 20 SEER2 efficiency, which is higher than the MrCool’s 17.5 SEER2. It runs on 115V and includes Wi-Fi smart control. This model is better if you want top-tier efficiency and app management. You get a quieter operation and stronger smart features, but you may lose the DIY quick connect convenience. It suits users who prioritize energy savings and smart home integration. You trade the easy self-installation for better efficiency ratings and modern connectivity options.
COSTWAY 12000 BTU 115V Mini Split
The COSTWAY 12,000 BTU 115V Mini Split offers 20 SEER efficiency, outperforming the MrCool’s 17.5 SEER2. It provides solid cooling power for standard rooms on a 115V circuit. However, it lacks smart app control, relying on manual operation instead. This model is better if you want high efficiency without needing Wi-Fi features. You get reliable performance and energy savings, but you sacrifice remote management capabilities. It suits buyers who prefer simple, efficient cooling without the complexity of smart home integration.
Mountman 12000 BTU 115V Mini Split
The Mountman 12,000 BTU 115V Mini Split delivers 19 SEER2 efficiency, which is better than the MrCool’s 17.5 SEER2. It covers up to 600 square feet, slightly more than the MrCool’s 550 square feet. It runs on standard 115V power but lacks smart home features. This model is better if you need strong cooling for medium rooms without app control. You get higher efficiency and a bit more coverage area, but you give up the DIY quick connect and smart connectivity. It suits users who prioritize performance over convenience.

Are these mini splits suitable for DIY installation?
The MrCool DIY Select is designed specifically for DIY installation with pre-charged quick connects. Other models like the Rellytech and Mountman are also suitable for standard 115V setups.
