10 Best Easy To Install Window Air Conditioner 2025 in the United States

The Midea 8,000 BTU Smart Inverter Window Air Conditioner is a solid choice for cooling and heating rooms up to about 350 square feet. Its cooling power is suitable for medium to large rooms, while the heat pump function adds versatility for cooler months (working best above 41°F). The unit is Energy Star certified and uses inverter technology, which means it cools efficiently, potentially saving you up to 35% on energy compared to older models. Installation is designed for double-hung windows with a specific size range, and comes with an installation kit, making it relatively straightforward for most users to set up without professional help. Noise-wise, it operates quietly at about 45 dB, which is low enough to avoid disturbing conversations, work, or sleep. The dimensions are compact enough for most standard windows, though checking your window measurements ahead of time is important.

Additional features include WiFi connectivity for remote control via an app or voice assistants like Alexa and Google Assistant, multiple modes (cool, heat, dry, fan), adjustable fan speeds, and a washable filter for easier maintenance. The supplemental heating only works above 41°F, which might limit its usefulness in colder climates as a heat source. Also, while the unit is fairly quiet, 45 dB may still be noticeable in very quiet rooms. The included remote and timer functions add convenience but the 1-year warranty is fairly standard and might feel limited for some buyers. For those seeking a user-friendly, energy-efficient window air conditioner that also offers heating and smart controls, this Midea model covers all the basics well and adds useful extras without being complicated.

The Midea 5,000 BTU EasyCool Small Window Air Conditioner is a solid choice for cooling small spaces up to 150 sq. ft., such as bedrooms, living rooms, or home offices. It offers an adequate cooling capacity and an efficient energy usage with a CEER of 11.0, which helps keep energy costs down. The unit operates quietly at 57 dB, making it less disruptive than many other air conditioners and quieter than a typical household refrigerator.

This model features easy-to-use mechanical controls and a removable and reusable air filter, simplifying maintenance. Its compact dimensions (15.35"D x 15.98"W x 12.05"H) make it suitable for smaller windows (23''-36'' wide and at least 13'' high). The installation process is straightforward and all necessary mounting accessories are included, although you will need a screwdriver and possibly pre-drilled holes.

Some additional features include multiple temperature settings, fan speeds, and air direction options for customized comfort. One downside is that it is not Energy Star certified, but its energy efficiency is still respectable. The unit also comes with a 1-year parts and labor warranty. At 35.3 pounds, it’s relatively easy to handle, though some users may find it a bit heavy.

The LG 12,000 BTU Smart Window Air Conditioner is a solid choice for cooling large rooms up to 550 square feet, such as kitchens or living rooms. With a cooling capacity of 12,000 BTUs and a Seasonal Energy Efficiency Ratio (SEER) of 12, it offers efficient cooling. The unit boasts multiple fan speeds and auto cool, allowing you to customize airflow, and also has a convenient 24-hour on/off timer and 4-way air deflection for more precise temperature control.

One of the standout features is its smart technology, including LG ThinQ, which lets you control the air conditioner remotely via your phone or voice commands using Amazon Alexa or Google Assistant. This is great for tech-savvy users who appreciate modern conveniences. Installation is relatively easy, supported by an included installation kit, though the unit does weigh 81 pounds, which might require some assistance. The noise level is reasonably low at 52 dB on its lowest setting, which is quiet enough for most users.

Despite not being Energy Star rated, which might affect energy-conscious buyers, it doesn't have the absolute quietest operation but is still more than acceptable for most households. The auto restart function is particularly useful in the event of power outages, ensuring your cooling is resumed without manual intervention. This air conditioner offers a great mix of power, convenience, and smart features, making it an excellent option for those looking for an easy-to-install, high-capacity window unit with modern controls.
