Buying Guide: Selecting the Best Air Conditioner Without a Window
When choosing an air conditioner that doesn’t require a window, consider the following key factors to ensure you purchase a unit that meets your cooling needs effectively and efficiently.
Cooling Technology
- Portable Refrigerant ACs: These resemble traditional air conditioners using refrigerant to cool air. They often come with exhaust hoses and require venting but some models are designed without window installation using other exhaust solutions.
- Evaporative Coolers: These are windowless, working by evaporating water to cool air. Best suited for dry climates, they save energy but may add humidity.
Room Size and Cooling Capacity
Choose a unit with adequate BTU or cubic feet per minute (CFM) rating based on your room size. Using a higher BTU air conditioner than needed can lead to excessive humidity, while undersized units struggle to maintain comfort.
Portability and Size
For spaces without windows or where mobility is important, consider dimensions, weight, and features like handles or wheels to ensure easy movement between rooms or storage.
Functionality and Modes
Look for multi-functional units offering fan, dehumidifier, and cooling modes. Additional features like timers, remote controls, oscillation, and adjustable fan speeds improve comfort and convenience.
Maintenance
Check for washable or replaceable filters and easy access to water tanks or drainage ports. Automatic water evaporation is a plus for reducing maintenance chores.
Noise Level
For bedrooms or offices, select units with low noise output (measured in decibels) to avoid disturbances during sleep or work.
Energy Efficiency
Look for ENERGY STAR certification or energy efficiency ratings like CEER to help reduce electricity consumption and costs over time.
