10 Best Window Units With Heat 2025 in the United States

The Midea MAW12HV1CWT is a versatile window air conditioner designed for year-round comfort, offering both cooling and heating functions. With a cooling capacity of 12,000 BTU, it is well-suited for large rooms up to 550 square feet. A notable strength of this unit is its energy efficiency, as it utilizes inverter technology that can save up to 35% on energy costs compared to standard models. The Energy Star certification further underscores its eco-friendly design.

Operating at a quiet level of just 45 dBA, this air conditioner is ideal for bedrooms, allowing for peaceful sleep or undisturbed work during the day. The electronic control panel, remote control, and compatibility with smart home systems like Alexa and Google Assistant make it user-friendly, allowing you to manage settings from anywhere.

However, there are some considerations to keep in mind. The heating function may not be effective if the outdoor temperature drops below 41°F. Additionally, while the installation is straightforward, it requires specific window dimensions, which could limit installation options for some users. The unit measures 19.41”W x 22.17”D x 13.9”H, so it's important to ensure your window can accommodate it.

In terms of maintenance, the washable filter is easy to access, promoting regular upkeep for optimal performance. Although the noise level is generally low, it can reach up to 58 dB under certain conditions, which might be noticeable in quieter settings.

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 Whynter Portable Air Conditioner and Heater is a versatile unit designed to cover areas up to 500 sq ft, boasting a cooling capacity of 14,000 BTU. It operates on a dual-hose system, which generally offers better efficiency in cooling compared to single-hose models. Its Energy Efficiency Ratio (EER) is 7.6, which is on the lower side, meaning it may consume more power compared to other units with higher EER. One significant advantage is its low noise level, operating at just 51 dB, making it a good choice for bedrooms or living spaces where noise might be a concern. However, it doesn't have an Energy Star rating, which could impact its operational cost over time.

The unit also includes a heating function, making it useful year-round. Its dehumidifying capacity is impressive at 71 pints per day, and it features auto-drain technology, reducing maintenance effort. Installation is relatively straightforward with the included window kit, although the unit is quite heavy at 85 pounds, which might make setup challenging for some users.

Additional features such as a remote control, multiple operational modes (cool, heat, dehumidify, and fan), and a storage cover bag add to its convenience. The SEER (Seasonal Energy Efficiency Ratio) could be better, and users should consider this in terms of long-term energy costs. This product is well-suited for those who need a portable and multifunctional air conditioner and heater but may not be the best option for those prioritizing high energy efficiency.
