Buying Guide for Air Conditioners That Don’t Need A Window
Selecting the right air conditioner that does not require a window involves understanding your room size, cooling needs, and installation options. Here are key factors to consider:
Type of Air Conditioner
- Windowless Portable Air Coolers: Utilize evaporative cooling and do not require exhaust ducts. Best for dry climates and smaller rooms that lack windows, but their cooling is less powerful than traditional ACs.
- Portable Air Conditioners: Typically use an exhaust hose vented through a window, so not entirely window-free but offer mobility.
- Window Air Conditioners: Require window installation but some models have unique designs that reduce noise or preserve window views.
Cooling Capacity & Room Size
BTU (British Thermal Units) rating indicates the cooling power. For small rooms (150-250 sq ft), 5,000-6,000 BTU is sufficient. Larger rooms need higher BTUs. Consider the area to ensure efficient cooling without wasting energy.
Noise Level
Look for decibel (dB) ratings if you prefer quiet operation, especially for bedrooms or workspaces. Units with noise levels below 55 dB are generally considered quiet.
Installation & Portability
For non-window rooms, truly windowless portable air coolers are best. Traditional window units require mounting kits and tools. Portable units without exhaust hoses are easier to move and place but usually provide less intense cooling.
Energy Efficiency
Efficient units reduce electricity bills. Check for energy-saving modes, CEER ratings, and low power consumption features. Evaporative coolers offer lower power use but depend on dry air conditions.
Additional Features
- Timers and remote controls provide convenience.
- Multiple fan speeds and cooling modes for customized comfort.
- Air filters that are washable or reusable help maintain indoor air quality.
- Oscillation or air direction controls improve airflow distribution.
Choosing the right no-window air conditioner depends on balancing cooling power, noise, ease of use, and how you plan to install or move the unit. Portable evaporative coolers are best for windowless setups, while high-efficiency window-style units suit those with window access but wanting quiet, unobtrusive cooling.
