10 Best Garage Air Conditioner Unit 2025 in the United States

The BLACK+DECKER Portable Air Conditioner offers a cooling capacity of 12,000 BTU (8,000 BTU SACC), suitable for rooms up to about 550 square feet, making it a reasonable choice for a moderately sized garage. It combines a dehumidifier and fan in one unit, which is beneficial in garage environments where dampness can be an issue. The Follow Me remote control enhances comfort and convenience by allowing you to set the temperature more precisely using the remote as a thermostat.

Installation is straightforward with the included window kit that vents hot air outside, although it may be somewhat challenging if your garage lacks a suitable window setup. The unit is portable with wheels and handles, allowing easy movement as needed. The noise level is moderate at about 52 decibels, which should not be too distracting while working in the garage. However, the energy efficiency ratio (SEER) is 5.8, which is relatively low, potentially leading to higher electricity consumption compared to more efficient models. Additionally, this model is not Energy Star certified, limiting its energy-saving potential.

The water tank capacity is small at 0.8 liters, but the auto water evaporation feature reduces the frequency of emptying. This BLACK+DECKER unit suits those looking for a portable cooling solution that also addresses humidity in a garage setting. If energy efficiency and very quiet operation are top priorities, other options may be more suitable.

The BLACK+DECKER Smart Portable Air Conditioner offers strong cooling capacity with 14,000 BTU, suitable for spaces up to 700 sq. ft., which should cover most garages comfortably. It also functions as a dehumidifier and fan, adding versatility to handle humidity and air circulation, important in garage environments. With a SEER rating of 6.2, it’s reasonably efficient but not the most energy-saving option available. Installation is user-friendly thanks to the included window kit and portable design—no permanent setup is required. Noise level is moderate at 54 dB, which might be noticeable but not overly disruptive during typical use.

Temperature control is enhanced by a remote with a 'Follow Me' feature that uses the remote’s location to keep the area comfortable, plus smart Wi-Fi and voice control compatibility add convenience if you want to adjust settings remotely. The washable filter is a practical and cost-saving feature for easy maintenance.

The 1-year warranty is fairly standard but somewhat short, and at 62.4 pounds, the unit is not the lightest portable model, so moving it around might require some effort. While the SEER rating is decent, more energy-efficient units exist if power consumption is a priority. This unit represents a solid choice for those seeking a combination of portability, decent cooling power, and smart features for their garage or similarly sized space, with manageable noise and easy setup.

The GE Window Air Conditioner Unit offers 5,100 BTU of cooling, making it suitable for small spaces like bedrooms or home offices up to about 150 sq ft. It’s fairly easy to install with the included EZ Mount kit, designed specifically for double-hung windows.

The unit operates quietly at 56 decibels, which means it won’t be too disruptive, even during nighttime use. It provides two fan speeds and two cooling modes, with 10 temperature settings that allow for fairly precise customization of the comfort level. The washable filter is simple to remove and clean, helping to maintain good performance over time.

The energy efficiency ratio is relatively low at 2.6 SEER and it carries only a 1-star energy rating, indicating it may use more electricity compared to more efficient models. It does not list a dehumidification feature, which might be a consideration in humid environments. Weighing 36 pounds, it is somewhat bulky but typical for window units. This model works well as a straightforward, budget-friendly solution for cooling small rooms but may not be ideal if energy efficiency or advanced moisture control are priorities.
