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 SereneLife Small Air Conditioner Portable 10,000 BTU is a versatile choice for cooling a garage. Its notable cooling capacity can comfortably manage spaces up to 450 sq ft, making it suitable for medium-sized garages. With a BTU rating of 10,000 (ASHRAE) and a 6,000 BTU SACC, it provides effective cooling performance. The unit also includes heating capability with 9,000 BTU, offering year-round utility.

The built-in dehumidifier is a significant advantage, reducing humidity levels and enhancing comfort during hot, sticky days. The unit's four operating modes (cooling, heating, dehumidifying, and fan) allow for flexibility in different weather conditions, and the automatic swing mode ensures better air circulation throughout the space. The included remote control and digital touch panel are user-friendly features that enhance convenience. Portability is another strength, with a design that includes rolling wheels for easy movement. However, at 56.5 pounds, it might be a bit hefty for some users.

Installation is straightforward with the provided window mount exhaust kit, and no assembly is required, which is a plus. Energy efficiency is decent. The noise level ranges from 52 to 56 dB, which is relatively quiet for an AC unit but may still be noticeable, especially during quieter times.

This portable air conditioner is a reliable and multifunctional option for individuals needing a flexible cooling and heating solution for their garage.

The LG 12,000 BTU Smart Window Air Conditioner is a robust option for cooling spaces up to 550 square feet, making it suitable for a large garage. Its strength lies in the high cooling power, customizable cooling and fan speeds, and smart control features through LG ThinQ, Alexa, and Google Assistant. This makes it easy to manage the temperature from anywhere via smartphone or voice commands, which adds convenience and energy efficiency by potentially reducing unnecessary usage.

The unit also has a low noise operation, with sound levels as low as 52 dB, which is relatively quiet and won't cause significant disturbance while working in the garage. Additionally, features like auto-restart ensure the unit turns back on automatically after a power interruption, and the 4-way air deflection maximizes cooling efficiency by directing airflow in multiple directions.

However, there are some drawbacks to consider. The unit's Seasonal Energy Efficiency Ratio (SEER) is 12, which is modest but not exceptional. It's not Energy Star-rated, which might be a concern for users focused on energy savings. Weighing 81 pounds, it may require substantial effort to install, and regular maintenance is necessary due to features like the dust filter and dehumidifier. Lastly, it needs 115 volts, which is standard for most households but should be verified for the garage's electrical setup.
