10 Best Ac Unit For Garage 2025 in the United States

The BLACK+DECKER Smart Portable Air Conditioner with Heat is a versatile option for garage use. It boasts a powerful cooling capacity of 14,000 BTU ASHRAE (10,000 BTU DOE), suitable for rooms up to 700 sq. ft., making it a good fit for larger garages. Additionally, it offers 12,000 BTU heating, making it useful year-round.

It's a portable unit, which means it's easy to move and install without the need for permanent fixtures. The included installation kit simplifies setting it up, even for those not familiar with AC installations. Its dehumidifier and fan functions add to its utility in varying weather conditions. Energy efficiency is moderate, with a SEER of 6.2, not qualifying for Energy Star ratings, which might impact long-term cost savings.

Noise level is relatively low at 54 dB, ensuring it won’t be overly disruptive during use. The smart features, including Wi-Fi connectivity and voice control via Amazon Alexa or Google Assistant, offer convenience for remote operation, particularly useful in a garage setting. The Follow Me remote enhances temperature control by acting as a thermostat. Potential drawbacks include its energy efficiency and the weight of the unit (35 pounds).

The GE 5,000 BTU Window Air Conditioner is a good choice if you need to cool a small space like a garage or a room up to 150 square feet. Its cooling power is appropriate for compact areas such as small bedrooms, home offices, or studios. The unit offers two fan speeds and two cooling modes, along with 10 temperature settings, allowing you to adjust the airflow and temperature to your liking. It operates quietly at about 56 decibels, which makes it suitable for nighttime use without causing much disturbance.

Installation is fairly simple thanks to the included EZ Mount kit, designed for double-hung windows of specific dimensions, so you won’t need professional help. The unit uses R-32 refrigerant, which is more environmentally friendly than older types, and it features a washable filter to keep maintenance easy and cost-effective. This model has a modest energy efficiency ratio (SEER of 11), which is decent but not the best for long-term energy savings, especially if you plan to run it frequently. It lacks advanced features like a remote control or smart connectivity, so adjustments must be made manually.

The AC weighs under 5 pounds, making it relatively lightweight for a window unit. While it’s not designed for larger spaces or heavy-duty garage cooling, it delivers solid performance for smaller areas with minimum noise and straightforward installation.

The LG 5,000 BTU Window Air Conditioner is designed to cool small to medium spaces up to 150 square feet, making it a reasonable choice for garages of similar size or other compact rooms. Its cooling power is modest, suitable if your garage is roughly 10 by 15 feet or less. It operates quietly at around 50-52 decibels, which is gentle enough to avoid being disruptive if you spend time in the garage working or relaxing. The unit offers two cooling and fan speed options, allowing some flexibility to adjust airflow according to your comfort.

Installation is straightforward with the included window kit, and maintenance is simplified by a slide-out washable filter, helping keep the unit running efficiently without extra costs. The AC also features auto-restart after power outages, which is convenient if you live in an area with unstable electricity. However, in terms of energy efficiency, it has an EER (SEER) of about 11.2 and does not have the Energy Star certification, meaning it may consume more power compared to more efficient models if used frequently.

If your garage is larger than 150 square feet, this unit might struggle to maintain a cool temperature. Additionally, as a window unit, it requires a suitable window for installation, which might not be ideal for all garage setups. This LG unit provides a quiet, easy-to-install AC solution for smaller garage spaces, balancing basic functionality and user-friendly features without high energy efficiency or large cooling capacity.
