This GE window air conditioner is designed to cool small rooms up to 150 square feet, making it a solid choice for bedrooms, small living spaces, or home offices. With a cooling power of 5,100 BTUs, it efficiently provides sufficient cooling for these compact areas. Its noise level is rated at 56 decibels, which is relatively quiet and suitable for nighttime use without causing much disturbance. The unit offers 2 cooling modes and 2 fan speeds, along with 10 temperature settings, giving users simple control over cooling comfort.

Installation is fairly straightforward with the included EZ Mount kit, but it requires a double-hung window fitting within specific size limits (about 22 to 36 inches wide and 13 inches high), so make sure your window matches these dimensions. Its energy efficiency ratio (EER) is on the lower side at 2.6, and it carries only a 1-star energy rating, meaning it may not be the best pick if you prioritize energy savings or lower electricity bills. A positive feature is the washable and removable filter, which helps keep the unit running smoothly with minimal maintenance.

The unit is compact and weighs 36 pounds, which is manageable for most users to install. It holds a 4.3-star rating from thousands of reviewers, reflecting strong customer satisfaction. Those needing a larger cooling capacity or higher energy efficiency might want to consider other models. This GE air conditioner provides a dependable, quiet, and easy-to-install option for small spaces, especially if budget and simplicity are your main concerns.

Noise Level
This air conditioner is quieter than many other models, making it suitable for those who are sensitive to noise while sleeping.
Cooling Capacity (BTUs)
The inclined cooling grill design helps direct cool air to the ceiling, preventing hot air pockets and enhancing overall cooling efficiency.
Energy Efficiency Ratio (EER)
The energy-saving mode is excellent, allowing the fan to shut off with the compressor and then periodically sample the air temperature.

The LG 18,000 BTU Window Air Conditioner is designed to effectively cool large rooms up to 1,000 square feet. One of its standout features is the quiet operation, with a noise level of 61 dB, which is relatively quiet for a unit of this size and capacity. It offers a strong cooling capacity of 18,000 BTUs, making it suitable for substantial spaces like living rooms or large bedrooms. The unit is equipped with multiple fan speeds and an auto cool function, allowing for customized cooling and airflow. The addition of a remote control enhances user convenience, enabling you to control the air conditioner from a distance. The auto restart function is particularly useful during power outages as it automatically restores the previous settings when power returns, ensuring continuous comfort without manual intervention.

Its energy efficiency ratio (EER) is 10.3, which is decent but not the highest in its class, meaning it could be more energy-efficient. However, it includes a filter light reminder for easy maintenance, alerting you when the filter needs cleaning. The size and installation are typical for a unit of this capacity, with dimensions of 28.13 x 26 x 17.7 inches and a weight of 130 pounds, which might require two people for installation. The unit also features a 4-way air deflection system and a dehumidifier function, adding to its versatility.

On the downside, it is not Energy Star certified, which might be a consideration for those seeking the highest energy efficiency standards. Additionally, some users might find the size and weight cumbersome during installation. Despite these minor drawbacks, the LG 18,000 BTU Window Air Conditioner remains a solid choice for those needing a powerful and relatively quiet cooling solution for larger spaces.

Buying Guide for the Best Quiet Air Conditioning Window Units

When choosing a quiet air conditioning window unit, it's important to consider several key specifications to ensure you get the best fit for your needs. A quiet unit can make a significant difference in your comfort, especially if you plan to use it in a bedroom or office where noise levels are a concern. Here are the key specs to look at and how to navigate them to find the right unit for you.
Noise LevelNoise level is measured in decibels (dB) and indicates how loud the air conditioning unit will be when in operation. This spec is crucial if you want a quiet environment. Units typically range from 40 dB (very quiet) to 60 dB (moderate noise). For a bedroom or office, aim for a unit that operates at 50 dB or lower. If you are particularly sensitive to noise, look for units that are specifically marketed as 'quiet' or 'ultra-quiet'.
Cooling Capacity (BTUs)Cooling capacity is measured in British Thermal Units (BTUs) and indicates how much heat the unit can remove from a room per hour. This is important to ensure the unit can effectively cool your space. Units range from 5,000 BTUs (suitable for small rooms up to 150 square feet) to 24,000 BTUs (suitable for large rooms up to 1,500 square feet). To pick the right one, measure your room's square footage and match it to the appropriate BTU rating. For example, a 200 square foot room would need a unit with around 6,000 BTUs.
Energy Efficiency Ratio (EER)The Energy Efficiency Ratio (EER) measures the unit's efficiency in converting electricity into cooling power. A higher EER means better energy efficiency, which is important for reducing electricity bills and environmental impact. EER values typically range from 8 to 12. For a more energy-efficient unit, look for an EER of 10 or higher. Consider your usage patterns; if you plan to use the unit frequently, a higher EER can lead to significant savings over time.
Size and InstallationThe size and installation of the unit are important for ensuring it fits your window and can be installed properly. Measure your window dimensions and compare them to the unit's specifications. Some units are designed for standard windows, while others may require additional support or modifications. Ensure the unit comes with a proper installation kit and clear instructions. If you are not comfortable with DIY installation, consider professional installation services.
Additional FeaturesAdditional features can enhance the usability and convenience of the air conditioning unit. Look for features such as remote control, programmable timer, sleep mode, and adjustable fan speeds. These features can make the unit more user-friendly and adaptable to your specific needs. For example, a programmable timer allows you to set the unit to turn on or off at specific times, which can be useful for maintaining a comfortable temperature while saving energy.
