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 LG 7,500 BTU Window Air Conditioner is designed for cooling medium-sized rooms up to 320 sq. ft., making it suitable for bedrooms, living rooms, or small offices. One of its standout features is the supplemental heat option, which provides warmth during cooler days, allowing for year-round use. Its low noise performance, operating as quietly as 50dB in low mode, is another advantage, ensuring that it won’t disrupt your peace while functioning.

The unit offers flexibility with two cooling, heating, and fan speeds, letting users customize airflow according to their comfort needs. The auto restart feature is practical, automatically turning the unit back on after a power outage, which is convenient for maintaining temperature consistency without needing manual intervention.

There are some drawbacks to consider. While the SEER rating is acceptable at 13, it doesn't carry the Energy Star certification, which may be a concern for those who prioritize energy efficiency. The unit’s weight of 69 pounds might pose a challenge during installation, especially for single users. Additionally, while it cools effectively for rooms up to 320 sq. ft., its cooling power may not suffice in larger spaces, limiting its versatility. The remote control adds convenience, but potential users should note that some may prefer a unit with a higher energy efficiency ratio or additional smart functions for modern living. The LG 7,500 BTU Window Air Conditioner stands out due to its heating capabilities and low-noise operation, yet those seeking a highly energy-efficient model might want to explore other options.
