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.

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.

Additional Features
Efficiently heats or cools the room, making it versatile for year-round use.

The Keystone 18,800 BTU Window-Wall Air Conditioner with 16,000 BTU Supplemental Heating is designed to provide efficient comfort for large spaces up to 1,000 sq. ft. It offers a high cooling capacity of 18,000 BTUs and a supplemental heating capacity of 16,000 BTUs, making it suitable for year-round use. However, it's important to note that the heating function is meant to supplement existing heat sources rather than serve as the primary heating method.

The unit has a Seasonal Energy Efficiency Ratio (SEER) of 10.7, which is reasonable but not outstanding, and it is not Energy Star rated. This means while it offers energy-saving modes like 'Energy Saver' and 'Sleep,' it may not be as energy-efficient as other models in its category. Installation is facilitated by a window installation kit, and the unit can be mounted either through a window or wall, which adds flexibility.

The noise level is rated at 55 dB, which is moderate and should be acceptable for most users, though not the quietest on the market. Additional features include a smart remote with temperature sensing, dehumidification, and a 4-way swing for better air distribution, enhancing user convenience and comfort. The unit also has a filter light reminder to help maintain optimal performance. Weighing 117.3 pounds, it might require some assistance during installation. Priced competitively, this unit offers good value, but those seeking top-tier energy efficiency might want to consider other options.

Buying Guide for the Best Thru The Wall Ac With Heat

When choosing a thru-the-wall air conditioner with heat, it's important to consider several key specifications to ensure you select the best model for your needs. These units are designed to be installed through an exterior wall, providing both cooling and heating capabilities. Understanding the key specs will help you make an informed decision and ensure the unit meets your specific requirements.
Cooling Capacity (BTUs)Cooling capacity, measured in British Thermal Units (BTUs), indicates how much heat the air conditioner can remove from a room per hour. This spec is crucial because it determines the unit's ability to cool a space effectively. For small rooms (up to 150 square feet), a unit with 5,000-6,000 BTUs is sufficient. Medium-sized rooms (150-300 square feet) require 7,000-8,000 BTUs, while larger rooms (300-450 square feet) need 10,000-12,000 BTUs. Choose a unit with the appropriate BTU rating based on the size of the room you intend to cool.
Heating Capacity (BTUs)Heating capacity, also measured in BTUs, indicates how much heat the unit can provide. This is important for ensuring the space stays warm during colder months. Similar to cooling capacity, the heating capacity should match the size of the room. For small rooms, 5,000-6,000 BTUs are adequate, while medium rooms need 7,000-8,000 BTUs, and larger rooms require 10,000-12,000 BTUs. Select a unit with the right heating capacity to maintain a comfortable temperature in your space.
Energy Efficiency Ratio (EER)The Energy Efficiency Ratio (EER) measures the unit's cooling efficiency by dividing the BTUs by the power consumption in watts. A higher EER indicates a more efficient unit, which is important for reducing energy costs and environmental impact. EER values typically range from 8 to 12. For better energy savings, look for units with an EER of 10 or higher. Consider your energy consumption preferences when choosing the EER rating.
Installation RequirementsThru-the-wall air conditioners require a specific wall sleeve for installation, which provides structural support and ensures a proper fit. This spec is important because it affects the ease and cost of installation. Make sure the unit you choose is compatible with your wall sleeve or includes one. Additionally, check the dimensions of the unit and the wall opening to ensure a proper fit. Consider the installation process and whether you need professional assistance.
Noise LevelNoise level, measured in decibels (dB), indicates how loud the unit will be during operation. This is important for maintaining a comfortable and quiet environment, especially in bedrooms or living areas. Noise levels typically range from 50 to 60 dB. For a quieter operation, look for units with noise levels below 55 dB. Consider where the unit will be installed and how important noise level is to your comfort.
Additional FeaturesAdditional features can enhance the functionality and convenience of the unit. Common features include remote control, programmable thermostat, sleep mode, and energy-saving mode. These features are important for improving user experience and energy efficiency. Determine which features are most important to you based on your lifestyle and preferences. For example, a remote control can be convenient for adjusting settings from a distance, while a programmable thermostat can help maintain a consistent temperature.
