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 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.

The LG 18,000 BTU Heat and Cool Window Air Conditioner with WiFi Controls is a versatile unit designed for medium to large rooms up to 1,000 sq. ft. It offers both heating and cooling functions, making it suitable for year-round use. One of its standout features is the LG ThinQ technology, which allows you to control the unit remotely via your phone or through voice commands with Amazon Alexa and Google Assistant. This adds a layer of convenience, allowing you to adjust settings from anywhere.

The unit has customizable cooling and heating options with 2 speeds for both, along with a 24-hour timer to create a personalized schedule. Additionally, the auto restart feature ensures your comfort isn't disrupted by power outages, as the unit will resume operation automatically. Installation should be straightforward with the included window installation kit, and its dimensions are relatively standard for window units, though its weight (126.5 pounds) might require some assistance to install.

In terms of energy efficiency, the unit has an EER of 11.1, which is decent but not the highest in its class, and it does not have an Energy Star rating. Noise levels are rated at 57 dB, which is moderate; it may not be the quietest unit but is by no means excessively loud. Additional features include a remote control, filter light reminder, and dehumidifying function. This air conditioner is ideal for someone looking for a reliable, year-round heating and cooling solution with modern smart features.
