10 Best Mini Split Ac For Garage 2025 in the United States

The MRCOOL Easy Pro 12K BTU mini split is a solid choice for cooling or heating a garage or small space up to about 550 square feet. It offers 12,000 BTUs, providing adequate power for typical garage sizes. With a SEER rating of 19.5, it delivers notable energy efficiency, helping reduce electricity costs while maintaining a comfortable environment.

Installation is designed to be DIY-friendly and includes a 16-foot lineset, which can reduce the need for professional installation if basic setup tasks are manageable. The unit operates at a reasonably low noise level of 43 decibels, ensuring it won't be overly loud or distracting during use. Its heating and cooling functions make it suitable for year-round use.

Additional features include a timer mode, refrigerant leak detection, and Active Clean Technology that helps maintain air quality and simplifies filter cleaning. It carries a 2-star BEE energy rating, which is moderate compared to higher-rated models. This mini split is well-suited for garage owners seeking a reliable, energy-efficient unit with heating capability, smart features, and quiet operation, especially those comfortable with handling installation.

The Senville 36000 BTU Dual Zone Mini Split Air Conditioner Heat Pump is a strong option if you need to cool and heat a large space, like a garage up to around 2000 square feet. With a 3-ton capacity and a high SEER rating of 22, it promises energy-efficient performance that helps keep electricity costs lower. It operates quietly at just 24 decibels, which is great for a garage where noise can be disruptive. This system stands out because it offers dual zone control, meaning you can independently set temperatures in two different areas—ideal if your garage has separate zones or adjoining rooms.

Heating is also included, and it works well even in very cold temperatures down to -22°F, which is useful if you want to use it year-round. The unit is Alexa-compatible, allowing remote temperature control through voice commands or an app, adding convenience and the ability to save energy when you're away. Installation is split-type and professional setup is required, so it’s not a DIY-friendly model. One thing to consider is its size and weight, which might require planning for space and support.

Noise levels are moderate at 43 dB, making it quieter than many traditional AC systems, beneficial if the garage is also used as a workspace. The unit includes smart features like leakage detection and a durable Gold Fin condenser coating that prevents rust, important qualities in a garage environment.
