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 LG 23,000 BTU Window Air Conditioner with Heat is a powerful unit designed to serve large rooms up to 1,400 square feet, making it suitable for living rooms, dens, bedrooms, or offices. It offers both cooling and heating functions, making it versatile for year-round use. With a high cooling power of 23,000 BTU, it can efficiently cool large spaces. The heating capacity is an added bonus for cooler days, providing supplemental heat to maintain a comfortable temperature indoors.

Its Energy Efficiency Ratio (EER) is 11.3, which is decent but not the best in its class, and it is not Energy Star rated, meaning it might not be the most energy-efficient option available. However, it operates at a relatively low noise level of 50-51 dB, ensuring minimal disturbance during operation. The unit also features multiple fan speeds for customizable airflow, a remote control for convenience, and an Auto Restart function, which is handy in the event of power outages.

Installation might be a bit cumbersome due to its large size and weight (145 pounds), so assistance may be needed. Additional features include a filter light reminder, dehumidifier function, and a 1-year parts and labor warranty. This window unit is ideal for those who need a robust and versatile cooling and heating solution for larger rooms, but it might not be the best choice for energy-conscious buyers.

The Amana Distinctions PTAC heat pump is a solid choice if you need a reliable window unit that can both heat and cool a medium to large room (up to about 750 sq ft). It delivers strong cooling power around 14,700 BTU and heating through a heat pump plus an electric heater, giving you flexibility in cold weather. The energy efficiency is quite good at 11.4 EER, helped by the environmentally friendly R32 refrigerant, which is better for the planet than older types.

Installation fits a standard 42-inch PTAC sleeve, which many apartments or hotels use, though you’ll need to get the sleeve and rear grille separately. It also offers useful features like washable filters, multiple fan speeds, and a backup emergency heat setting, adding convenience and reliability.

One trade-off is the unit’s size and weight (122 pounds), so it’s not the easiest to handle or install without help. If you’re looking for a dependable, efficient window unit with strong heating and cooling for a sizable space, this Amana model covers those well but expect a bit of effort during installation and moderate noise.
