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 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 Distinctions DHP153A35AA is a packaged terminal heat pump (PTHP) designed to provide both cooling and heating, making it suitable for spaces needing year-round climate control. It offers a solid cooling capacity of 14,700 BTUs and a heating capacity of 13,500 BTUs, which should comfortably cover medium-sized rooms or small apartments. The energy efficiency ratio (EER) of 10.6 indicates moderate energy savings, helping to keep electricity costs in check without pushing the limits of high-efficiency models. One of its strengths is the included 3.5 kW electric heat kit, which offers reliable supplemental heat during colder months.

Installation is straightforward as a standalone packaged unit, measuring 21" deep by 42" wide and 16" high; however, it is relatively heavy at 117 pounds, so professional installation might be advisable. The product uses R-410A refrigerant, which is common and environmentally friendlier than older types. Customers can appreciate that every unit undergoes thorough testing before shipment, adding confidence in reliability.

This unit serves as a dependable choice for those needing a balanced cooling and heating solution without complex installation or advanced smart features.
