10 Best Cheap Window Ac Unit 2025 in the United States

The Midea 8,000 BTU Smart Inverter Window Air Conditioner is a strong choice if you need to cool or heat a room up to about 350 square feet without spending too much. Its cooling capacity is solid for medium-sized rooms, and the unit includes a heat pump function, which is useful for keeping warm in milder cold weather (above 41°F). This makes it more versatile than many basic window ACs. It’s Energy Star rated and uses inverter technology, which means it’s designed to save on electricity—up to 35% compared to standard models—helping lower your energy bills.

Noise-wise, this unit performs well with a low noise level around 45 decibels, so it won’t disrupt conversations, work calls, or sleep. The size fits most double-hung windows easily, and installation comes with a kit to help set it up. The remote control and smart features (WiFi, Alexa, Google Assistant) add convenience, allowing you to adjust settings without needing to get up.

There are some limitations to consider: the heating function only works efficiently when outside temperatures are above 41°F, so it’s not suitable as a main heater in colder climates. Also, while its upfront cost is reasonable for a smart inverter unit, it may be pricier than the simplest window ACs without heat or smart controls. The 1-year warranty is fairly standard but might be short if you want longer coverage. If you want a budget-friendly window AC that’s quiet, energy efficient, and offers both cooling and supplemental heating with smart controls, the Midea 8000 BTU unit is a practical pick. Just keep in mind its heating limits and check that your window size fits the installation requirements.

The Midea 6,000 BTU Window Air Conditioner is a solid choice if you're looking for an affordable unit to cool small rooms up to 250 square feet, such as bedrooms or offices. Its 6,000 BTU cooling capacity is enough to quickly cool modest spaces, making it good for personal use rather than large or open areas. The unit offers three modes—cooling, fan, and dehumidifier—which adds flexibility to help maintain comfort in different conditions.

Energy efficiency is decent with a SEER of 12.1, although it doesn't have the Energy Star certification, so it might not be the most cost-saving option in the long run compared to some higher-end models. However, features like Eco mode and a programmable timer can help you save on electricity bills by allowing better control of usage. Noise-wise, it runs quietly at about 52 decibels on low, which is comparable to a normal conversation, so it won’t disrupt sleep or work. The size is compact with straightforward installation fitting window frames from 23 to 36 inches wide, and it comes with all the mounting hardware needed, although you will need your own screwdriver. The remote control and LED display make it easy to adjust settings from across the room.

Additional perks include a reusable air filter to trap dust and pet hair, which helps improve air quality, and a one-year warranty for peace of mind. On the downside, the unit is not Energy Star certified and is made in China, which some might consider when thinking about durability or parts availability. This Midea window AC unit is a practical, budget-friendly option for cooling small spaces quietly and with some energy-saving features, but if you want top-tier efficiency or to cool larger rooms, you may want to explore other models.

The LG 12,000 BTU Window Air Conditioner is a solid choice for those seeking an affordable and efficient cooling solution for rooms up to 550 square feet. It's particularly well-suited for bedrooms, living rooms, and medium-sized apartments. One of its standout features is the low noise performance, operating at just 52 dB in low mode, making it a good option for light sleepers or anyone needing a quieter environment.

The unit also offers flexibility with three cooling and fan speeds, as well as an Auto Cool setting, allowing users to customize their comfort level effortlessly. The digital control panel and included remote control add to its ease of use, while the 4-way air deflection ensures optimal air distribution throughout the room. Convenience is further enhanced by features like the filter light reminder, a washable filter, and a complete window installation kit.

The 24-hour timer is a handy addition for those looking to save on energy costs by scheduling the unit to turn on and off automatically. However, there are some drawbacks. Despite its cooling efficiency, the unit lacks an Energy Star rating, which may be a consideration for those particularly focused on energy conservation. Additionally, while it is efficient for its class, the Seasonal Energy Efficiency Ratio (SEER) of 13 is decent but not the highest available, meaning there are more energy-efficient models on the market.
