Buying Guide: How to Choose the Best Air Conditioner Without Window
Choosing the right air conditioner without a window installation depends on several factors. Consider the following key points to ensure you pick the appropriate model for your cooling needs.
Cooling Technology
- Evaporative Coolers: Use water evaporation for cooling; best in dry climates and smaller rooms; energy-efficient and windowless.
- Portable ACs with Venting: Use refrigerant and require a venting hose (usually to a window or vent); stronger cooling capacity but need window access for hot air exhaust.
Room Size and Coverage
Match the unit’s cooling capacity (measured in BTUs or coverage area) with your room size to ensure effective cooling. Evaporative coolers perform well in moderate areas but may not sufficiently cool large or humid rooms.
Installation Requirements
- Windowless models: No hose or window required, ideal for rooms without windows or ventilation options.
- Portable Models with Kits: Require venting hose installation, potentially needing a window or vent opening.
Noise Level
Check noise ratings if you intend to use the unit in bedrooms or quiet spaces. Some portable air conditioners offer quieter operation compared to traditional window units.
Additional Features
- Humidity control: Some models double as humidifiers or dehumidifiers.
- Oscillation and airflow speed settings for customized comfort.
- Remote control and programmable timers for convenience.
Energy Efficiency
Consider energy consumption and refrigerant types. Units with eco-friendly refrigerants (like R32) and high energy efficiency ratings help reduce utility bills and environmental impact.
