10 Best Heat And Cool Window Units 2025 in the United States

The Midea MAW12HV1CWT EasyCool Smart Inverter Air Conditioner is a versatile window unit that offers both cooling and heating, making it suitable for year-round comfort in spaces up to 550 square feet. One of its standout features is its energy efficiency; with a cooling capacity of 12,000 BTU and an EER of 13.3, it's designed to save on electricity bills, and the inverter technology helps maintain consistent temperatures while using less power.

Users will appreciate the quiet operation, with noise levels as low as 45 dBA, which is especially beneficial for bedrooms or workspaces. The unit's SmartHome capabilities allow for convenient control via a mobile app or voice assistants like Alexa and Google Assistant, adding to its user-friendly appeal. The remote control and multiple modes—cool, heat, dry, fan, and auto—give you flexibility in how you manage your indoor climate.

However, there are a few drawbacks to consider. The heat pump function is ineffective in temperatures below 41°F, which may limit its usefulness in colder climates. Additionally, the installation requirements specify compatibility with double-hung windows, which may not suit all users. While it is energy star certified, some users might find the cooling power insufficient for extremely hot days, especially in larger spaces, so it's important to assess your room size and climate needs.

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 BTU rating of 12,000, it is powerful enough for substantial cooling tasks. The Energy Efficiency Ratio (EER) of 12 is decent, providing a balance between performance and energy consumption without being the top performer in energy savings. The unit operates at a noise level as low as 52 dB, which is relatively quiet, making it suitable for spaces where you don't want a lot of background noise.

It includes a thermostat control and offers multiple fan speeds and auto cool features, allowing for more customization of your cooling needs. One of its standout features is the smart connectivity options via LG ThinQ, Amazon Alexa, and Google Assistant, giving users the convenience of controlling the unit remotely and through voice commands. This can be particularly useful for tech-savvy users who appreciate smart home integration.

The installation and size are typical for window units, with standard dimensions and an included installation kit to simplify setup. However, it's important to note that it is somewhat heavy at 81 pounds, which might require assistance during installation. Additional features like the auto restart function, 24-hour timer, and filter light reminder add convenience and efficiency. Those looking for a reliable, smart-enabled window air conditioner with robust cooling power will find this unit to be a good fit, though those prioritizing maximum energy efficiency might need to consider other options.

The LG 23,000 BTU window air conditioner with heat is designed for medium to large rooms up to about 1400 square feet, making it a solid choice for living rooms, bedrooms, or offices. Its high cooling power means it can handle sizable spaces efficiently. The unit offers both heating and cooling, which is convenient for year-round comfort without needing separate devices. It runs fairly quietly at around 50-51 decibels on low settings, which should be unobtrusive during sleep or work.

Energy efficiency is decent with a SEER rating of 11.3, although it doesn’t carry a specific energy star rating. This means it’s reasonably efficient but may use more power than some top-tier models. The unit includes a remote control and a filter light reminder, adding user-friendly features that make operation and maintenance easier. Multiple fan speeds let you customize airflow and temperature, and the auto restart function is helpful during power outages by automatically resuming operation.

Installation requires a standard window setup and the unit is somewhat bulky and heavy (around 145 pounds), so it might need two people or professional help to install. The size and voltage (230V) are typical for larger window units but check compatibility with your home's electrical system. The included installation kit is a plus, but the warranty covers just one year, which is fairly standard but on the shorter side. This LG model is a good fit if you need strong cooling and heating in a medium-large room and want convenient features like remote control and quiet operation. If you’re looking for the highest energy savings or a very lightweight unit, there may be better options, but this product provides reliable year-round comfort.
