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 MAW08V1QWT is a smart choice if you’re looking for an affordable window AC unit that covers the basics well. It cools rooms up to about 350 square feet with 8,000 BTUs, which is suitable for small to medium spaces like bedrooms or small living rooms. One of its biggest perks is energy efficiency: it uses advanced inverter technology and holds an ENERGY STAR certification, helping you save over 35% on power compared to traditional units. Noise won’t be an issue either, as it runs very quietly at just 32 decibels, making it great for light sleepers or home offices.

The unique U-shaped design is clever because it lets you keep your window partly open for fresh air and a view, plus an anti-theft lock adds safety. Installation is straightforward with the included bracket and works with common single or double-hung windows between 22 and 36 inches wide. On the downside, the unit weighs around 56 pounds, so it might require a bit of effort to mount safely. Also, while it has smart features like Wi-Fi control and voice assistant compatibility, these might be more than some users need and require a stable internet connection.

This Midea model combines efficiency, quiet operation, and handy modern controls into a compact design, making it a strong option if your window matches the size requirements and you want a low-noise, energy-saving AC without breaking the bank.

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.
