Buying Guide for the Best Air Conditioners For Rooms Without Windows
Choosing an air conditioner for a room without windows can be a bit challenging, but with the right information, you can find the perfect unit to keep your space cool and comfortable. The key is to understand the different types of air conditioners available and the specifications that matter most for your specific needs. Here are some important factors to consider when selecting an air conditioner for a windowless room.Type of Air ConditionerFor rooms without windows, portable air conditioners and ductless mini-split systems are the most common options. Portable air conditioners are easy to move and typically require a venting hose to expel hot air, which can be directed through a wall or ceiling. Ductless mini-split systems consist of an indoor unit and an outdoor compressor, connected by refrigerant lines, and are more permanent solutions. Choose a portable unit if you need flexibility and ease of installation, or a mini-split system for more efficient and quieter cooling.
Cooling Capacity (BTU)BTU stands for British Thermal Units and measures the cooling power of an air conditioner. The higher the BTU, the more cooling power the unit has. For small rooms (up to 150 square feet), a unit with 5,000-6,000 BTU is sufficient. Medium rooms (150-300 square feet) require 7,000-8,000 BTU, while larger rooms (300-500 square feet) need 10,000-12,000 BTU. Choose a unit with the appropriate BTU rating based on the size of your room to ensure efficient cooling.
Energy Efficiency Ratio (EER)The Energy Efficiency Ratio (EER) measures how efficiently an air conditioner uses energy. A higher EER indicates better energy efficiency, which can save you money on electricity bills. EER ratings typically range from 8 to 12. For optimal energy savings, look for units with an EER of 10 or higher. Consider your usage patterns and energy costs when selecting a unit with the right EER for your needs.
Noise LevelNoise level is an important consideration, especially if the air conditioner will be used in a bedroom or office. Noise levels are measured in decibels (dB), with lower numbers indicating quieter operation. Portable air conditioners generally range from 50 to 70 dB, while ductless mini-split systems can be as quiet as 20-30 dB. If you need a quiet environment, opt for a unit with a lower dB rating.
Installation RequirementsInstallation requirements vary depending on the type of air conditioner. Portable units typically need a venting hose to expel hot air, which can be installed through a wall or ceiling. Ductless mini-split systems require professional installation to connect the indoor and outdoor units. Consider your ability to install the unit yourself or the need for professional help when choosing the right air conditioner for your room.
Additional FeaturesAdditional features can enhance the functionality and convenience of your air conditioner. Look for units with programmable timers, remote controls, adjustable fan speeds, and sleep modes. These features can help you customize the cooling experience to your preferences and improve overall comfort. Think about which features are most important to you and choose a unit that offers them.
