10 Best Window Units With Heat 2026 in the United States

The Midea MAW08HV1CWT EasyCool Smart Inverter Air Conditioner Window Unit with Heat is a versatile option designed for year-round comfort. With an 8,000 BTU rating, it effectively cools and heats rooms up to 350 square feet. The unit performs well in terms of energy efficiency with a SEER of 14.5, potentially saving up to 35% on energy costs compared to standard models. It is Energy Star certified, ensuring lower electricity bills while maintaining comfort. Noise levels are impressively low, with operation as quiet as 45 dBA, which is ideal for maintaining a peaceful environment, whether you're working, watching TV, or sleeping.

Installation is straightforward, fitting double-hung windows with specific dimensions, and the included installation kit simplifies the process. Smart features enhance usability, including WiFi connectivity, compatibility with voice assistants Alexa and Google Assistant, and control via the SmartHome App. These features make it convenient to operate from anywhere.

However, it’s important to note that the heating function is supplementary and works best when outdoor temperatures are above 41°F, which might limit its use in colder climates. Also, at 56 pounds, the unit might be a bit heavy for some users to install by themselves. The remote control and washable filter are practical additions, contributing to ease of use and maintenance. For those looking for a smart, quiet, and energy-efficient unit that offers both cooling and heating, the Midea MAW08HV1CWT is a strong contender.

The Midea Inverter Window Air Conditioner with Heat is a solid choice if you want a versatile window unit for both cooling and heating in rooms up to 550 square feet. It offers a strong 12,000 BTU cooling capacity combined with a heat pump function for mild winter warmth. Energy-wise, it’s efficient with a CEER of 13.3 and Energy Star certification, helping save on electricity without compromising comfort.

One of its standout features is its quiet operation at just 45 decibels, which is gentle enough for bedrooms or living spaces without being distracting. Installation fits common double-hung windows between 24 to 38.5 inches wide, and the unit includes a remote, installation kit, and smart controls via an app or voice assistants, making it easy to adjust settings from anywhere. The built-in dehumidifier and washable filter add extra convenience.

The heating function won’t work if outdoor temperatures drop below 41°F, so it’s best for mild cold weather rather than harsh winters. Also, at about 58 pounds, it’s a bit heavy, so installation may require some help. If you want an efficient, quiet, and smart-controlled window unit that handles both cooling and supplemental heating well, the Midea is a reliable option—just keep in mind its heating limits in colder climates.

The BLACK+DECKER Smart Portable Air Conditioner offers solid cooling performance with a 14,000 BTU rating, suitable for rooms up to 700 square feet. Its portable design and included window installation kit make it a flexible choice for bedrooms or living rooms needing efficient cooling without permanent installation. One notable advantage is its smart connectivity, allowing control through a mobile app or voice commands via Alexa and Google Assistant, plus a 'Follow Me' remote that fine-tunes temperature based on where you are in the room.

Energy efficiency is moderate with a Seasonal Energy Efficiency Ratio (SEER) of 6.2, which is average for portable units but not outstanding if you’re looking to save on electricity bills. Noise level is about 52 decibels, which is noticeable but generally tolerable for most users during operation.

This model does not include a heating function, which is an important consideration since it’s labeled under the category of window units with heat. If you need a unit that also warms your room during colder months, this model won't meet that need. The size is somewhat bulky and weighs around 68 pounds, so while portable, it may not be easy to move frequently. This BLACK+DECKER unit performs well as a smart, portable cooling solution for medium to large rooms, with easy installation and useful remote features, but it offers average energy efficiency and noise levels and lacks heating capability.
