Buying Guide: Choosing The Best Air Conditioner Without a Window
When selecting an air conditioner that does not require a window, consider these important factors to meet your cooling needs effectively:
Type of Cooling Technology
- Evaporative Coolers: Use water evaporation to cool air; highly energy-efficient but best for dry climates.
- Portable Air Conditioners: Typically require venting through a window or wall but some models operate without exhaust.
- Window Units: Traditional cooling with higher BTU ratings but require window access for installation.
Room Size and Cooling Capacity (BTU)
Ensure the unit matches your room size. For example, 5,000–6,000 BTU units are adequate for up to 250 sq. ft. Larger spaces require higher BTU ratings for effective cooling.
Installation and Portability
If you cannot install a window unit, consider windowless or portable models that only need standard outlets. Portability allows you to move the unit between rooms and requires minimal setup.
Noise Level
Choose units with low operational noise (ideally below 55 dB) for bedrooms or offices where quiet comfort is important.
Energy Efficiency
Energy-efficient models reduce power consumption and operating costs. Look for units with good energy ratings or low wattage usage, especially important in portable or evaporative coolers.
Additional Features
- Remote Control & Timers: Enhance convenience for adjusting settings remotely.
- Filter and Maintenance: Removable washable filters improve air quality and ease cleaning.
- Multiple Speeds and Modes: Provide customizable cooling and energy savings.
