10 Best Window Units 2025 in the United States

The Frigidaire FHWC103TC1 Window Air Conditioner is a solid choice for cooling medium-sized rooms, thanks to its 10,000 BTU cooling capacity, which is suitable for spaces up to 450 square feet. The unit operates at a noise level of 54 dB, which is relatively quiet for most households. However, it's essential to note that it does not have an Energy Star certification, which means it may not be the most energy-efficient model available, despite its SEER of 10.9.

The installation is straightforward with the included window kit, and the dimensions (21.4 x 18.9 x 14.6 inches) should fit well in most standard windows. The multi-speed fan and additional features like remote control, filter light reminder, and washable dust filter add to its convenience and flexibility. Weighing 57.8 pounds, it's relatively easy to handle during installation.

While it requires 115 volts AC, it doesn't need any batteries for operation, though the remote requires 2 AAA batteries, which are included. This model is best suited for users looking for an affordable, reliable, and feature-rich window air conditioner without the emphasis on peak energy efficiency.

The Midea MAW12HV1CWT EasyCool Smart Inverter Air Conditioner Window Unit with Heat is a versatile option for large rooms up to 550 square feet, offering both cooling and heating functions. With a cooling capacity of 12,000 BTUs, this unit is designed to provide effective temperature control throughout the year. However, the heating function may not work efficiently when the outside temperature drops below 41°F.

It is equipped with a variety of useful features, including an LED display, multiple modes and speed settings, a 24-hour timer, and an energy-saving ECO mode, enhancing user convenience. Its compatibility with the SmartHome App and voice control via Alexa and Google Assistant allows remote operation, adding to its user-friendliness. The unit's energy efficiency is notable, with a high CEER rating of 13.3 and Energy Star certification, promising considerable energy savings.

A noise level as low as 45 dBA ensures quiet operation, making it suitable for bedrooms or home offices. Installation requires a window opening width between 24 to 38.5 inches and a vertical clearance of 14.5 inches. The air conditioner comes with an installation kit, remote control, and a washable filter for easy maintenance. However, its weight of 58 pounds might make installation a bit challenging for some users. Additionally, it requires regular cleaning of the filter to maintain optimal performance. This window unit is ideal for users looking for a combination of cooling and heating with modern smart features and energy efficiency, though its heating capabilities have some temperature limitations.

The Midea 12,000 BTU EasyCool Window Air Conditioner is a solid choice for cooling rooms up to about 350 square feet, making it well-suited for medium-sized bedrooms or small living spaces. Its 12,000 BTU capacity provides reliable cooling without being overpowered, and it also includes a dehumidifier and fan mode, which adds versatility for different comfort needs. The unit has an Energy Efficiency Ratio (EER) reflected by a SEER rating of 12, which means it can help save on electricity compared to less efficient models. One nice perk is the Eco mode and timer feature to further reduce energy use.

Noise-wise, it operates at around 55 decibels, roughly the sound of a quiet conversation or a household refrigerator, so it won’t be too disruptive in most rooms. Installation is fairly straightforward if your window measures between 23 to 36 inches wide and 14 inches high, with all mounting hardware included; however, you'll need your own screwdriver and might need to pre-drill holes for a secure fit. The reusable air filter is easy to clean, which helps maintain air quality and saves on replacement costs. A remote control with an easy-to-read LED display adds convenience when adjusting settings from across the room.

On the downside, it’s a bit heavy at nearly 75 pounds, so installation might require two people, and it’s designed for smaller spaces rather than large rooms or open areas. Also, the one-year warranty is standard but limited. This Midea unit offers a user-friendly, energy-conscious option with multiple comfort modes, making it ideal for those needing effective cooling and dehumidification in small to medium rooms.
