9 Best Thru The Wall Ac With Heat 2025 in the United States

The LG 9,800 BTU through-the-wall air conditioner with supplemental heat is designed for medium-sized rooms up to about 440 square feet, making it suitable for bedrooms or offices. It offers both cooling and heating functions, which is helpful for year-round comfort without needing separate units. The cooling capacity is around 10,000 BTUs, which aligns well with the room size it’s intended for. Heating is supplemental, meaning it can provide warmth but may not replace a full heating system in very cold climates.

The energy efficiency rating, at a SEER of 9.8, is average compared to newer models, so it provides decent but not the most energy-saving performance available. Noise level at 54 decibels is moderate; it won’t be completely silent but should be reasonably quiet for bedroom use. Installation requires a dedicated wall space and 230V power, which might need professional help if you’re not familiar with electrical work. Extra features like multiple fan speeds, 4-way air deflection, a remote control, filter reminder, and washable filter add convenience and flexibility. It also has an auto-restart after power outages, which is useful for continuous comfort.

The unit is not Energy Star certified, so energy costs could be higher than more efficient units. It is somewhat bulky and heavy, which could make installation a bit challenging. For those seeking a simple, dual-purpose wall unit for moderate room sizes and who accept average energy efficiency, this LG model is a solid option. However, if you prioritize very quiet operation or higher energy savings, exploring other models may be beneficial.

The LG 7,800 BTU Through the Wall Air Conditioner is a solid choice for cooling rooms up to 330 square feet, like bedrooms or offices. Its energy efficiency ratio (EER) of 10.7, aided by the R-32 refrigerant, makes it an energy-efficient option despite not being Energy Star rated. The unit operates at a noise level of 56 dB, which is relatively quiet for an air conditioner, so it shouldn't be too disruptive in a home setting.

This model offers three cooling speeds and three pre-programmed modes, including an Energy Saver mode, providing flexibility in managing room temperature. The inclusion of a remote control adds convenience, allowing adjustments from across the room. Installation is designed for through-the-wall setups, not standard windows, and it comes with a trim kit, mesh grille, and insulation foam, making it easier to install and maintain.

However, the unit does not have heating capabilities, which may be a drawback for those needing an all-in-one system for year-round use. The product is also somewhat heavy at 66 pounds, which could pose a challenge during installation. Its lack of an Energy Star rating might be a consideration for those looking for the most energy-efficient options.

The LG 9,800 BTU Through the Wall Air Conditioner is designed for cooling spaces up to 440 sq. ft., making it suitable for bedrooms, living rooms, and medium-sized apartments. It boasts an Energy Efficiency Ratio (EER) of 10.7, which means it's relatively efficient in terms of energy consumption. However, it does not have an Energy Star rating, which might be a consideration for those focused on energy savings.

The unit uses R-32 refrigerant, known for its efficiency and lower environmental impact. Installation is specific to through-the-wall setups and requires a 230V plug, which may necessitate an electrician for proper installation if your home isn't already equipped with this outlet type. The cooling capacity of 9,800 BTUs is complemented by the heating capability, though the specific BTU rating for heating isn't provided. It has a noise level of 56 dB, which is moderate but might be noticeable in a quiet room.

Additional features include three cooling and fan speeds, a remote control, pre-programmed modes, and a four-way air deflection system for better airflow distribution. The Energy Saver mode helps maintain temperature efficiently, and the Dry mode dehumidifies the room by removing up to 2.9 pints of moisture per hour. Accessories such as a trim kit, mesh grille, washable filter, and insulation foam make installation and maintenance straightforward. The unit is relatively heavy at 77 pounds and has dimensions that should be checked against your wall space.
