10 Best Mini Split For Garage 2025 in the United States

The Senville AURA Series Mini Split is a solid choice if you're looking to heat and cool a garage efficiently. It offers 9,000 BTU cooling capacity, which suits smaller to medium-sized garage spaces rather than large workshops. Its SEER rating of 28 means it runs very efficiently, saving on electricity bills over time. The inverter heat pump works well even in very cold weather, with reliable heating down to -22°F, which is great if you want to maintain a comfortable garage temperature year-round. Noise level is impressively low at 23.5 dB, so it won’t disturb activities or conversations while running.

The system comes complete with indoor and outdoor units and necessary installation hardware, but professional installation is mandatory to keep the warranty valid, and it isn’t a DIY setup. An added bonus is smart home compatibility—controlling the unit via Alexa or an app makes it easy to adjust settings remotely, which can be handy for pre-warming or cooling your garage before you arrive.

Its 0.75-ton capacity might be underpowered for very large or poorly insulated garages, and the warranty covers parts only, not labor costs. If you want a dependable, quiet, and energy-efficient mini-split with smart features for a small to medium garage, this unit is worth considering.

The Senville LETO Series Mini Split is a solid choice for heating and cooling a garage, thanks to its 12,000 BTU (1 ton) capacity, which suits small to medium spaces well. With a high SEER rating of 20.8, it’s energy efficient, helping keep electricity costs lower when running. It also doubles as a heat pump capable of warming your space down to about 5°F (-15°C), which is helpful in colder climates. The unit includes a versatile 4-in-1 function—cooling, heating, dehumidifying, and fan modes—giving you year-round comfort.

A standout feature is its Alexa compatibility, allowing you to control the system by voice or app, adding convenience. Installation comes with everything needed, but it requires professional setup, and the included line set supports up to 25 feet, so consider the distance from your outdoor condenser to the indoor unit. Mini splits generally run quietly, making it unlikely to disturb your garage workspace. The 5-year warranty on parts and compressor shows confidence in durability, though labor costs for installation aren’t covered.

One downside is that it’s not Energy Star certified, which might concern those seeking the strictest energy efficiency standards. This model balances strong performance and smart features, making it a practical option for someone looking to keep their garage comfortable year-round without breaking the bank.

The dual-zone feature allows for individual temperature settings in two areas, making it versatile for different needs within a garage or other spaces like bedrooms or offices. It boasts a high SEER rating of 22, indicating excellent energy efficiency, which can help reduce energy bills over time. Additionally, its heating capability is reliable, functioning well even in extremely cold temperatures as low as -22°F/-30°C, thanks to the Arctic Heat Pump technology.

This unit operates quietly at 24 dB, ensuring a noise-free environment, which is beneficial for a garage workspace or living area. One of its standout features is the Alexa compatibility, allowing for convenient voice control and temperature adjustments via an app, which adds to its appeal for tech-savvy users. The product includes a comprehensive kit with indoor air handlers, an outdoor condenser, and essential installation components, though it requires professional installation, which may be a drawback for those looking for a DIY option.

The unit is backed by a strong warranty of 5 years on parts and 10 years on the compressor, providing peace of mind regarding its durability and long-term performance. However, its relatively high weight of 147.7 pounds might pose a challenge during installation. The Senville SENA-36HF/D is an efficient and versatile mini-split system ideal for those needing reliable climate control in a garage or multiple rooms, with the added convenience of smart home integration.
