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 18,000 BTU Heat and Cool Window Air Conditioner is a strong choice if you need a reliable unit for medium to large rooms, up to 1,000 square feet. Its 18,000 BTU cooling and heating capacity means it can keep sizable spaces comfortable through summer and winter, making it versatile for year-round use. The supplemental heating option adds real value for colder days, which not all window units provide. One of its standout features is the smart control capability—using LG ThinQ technology, you can adjust settings remotely via your phone or voice commands with Alexa and Google Assistant, which is convenient for modern living. It also has two fan speeds and a 24-hour timer to help customize comfort and energy use.

Noise-wise, it runs at 57 dB, which is moderately loud but typical for a unit this powerful; it might be noticeable in very quiet rooms. The size and weight are on the larger side, so ensure your window can accommodate its 30.5 x 25.5 x 16.84-inch frame and that installation is manageable for you. One drawback is its Energy Efficiency Ratio (SEER) of 11.1 and the absence of an Energy Star rating, meaning it might not be the most energy-saving option, which could affect your electricity bill over time. However, features like auto restart after power outages and a filter light reminder add to ease of use and maintenance.

If you want a smart, powerful window unit that heats and cools efficiently for medium to large rooms and don’t mind a slightly higher energy use, this LG model is worth considering.

The Amana 9,000 BTU Distinctions PTAC heat pump is a solid choice for heating and cooling spaces up to about 350 square feet. It offers strong cooling power at 9,200 BTU and decent heat pump heating near 8,000 BTU, backed by a robust 3.5 kW electric heater for colder days. Its energy efficiency is good, with an 11.4 SEER rating and the eco-friendly R32 refrigerant, which is better for the environment than older types. Installation fits a standard 42-inch PTAC sleeve, making it suitable for many through-the-wall setups, though you’ll need to buy the sleeve and grille separately.

The unit is user-friendly, featuring 3 fan speeds, a fan-only mode, and compatibility with wired thermostats for convenient control. Maintenance is straightforward thanks to washable filters and protective features that help prevent freezing and moisture issues. While the product is quite heavy at 108 pounds, the secure front panel design helps reduce tampering, which is good for durability.

This PTAC unit is well suited for users looking for an efficient, reliable heating and cooling solution with easy maintenance and solid performance, especially in moderate-sized rooms.
