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.
