Buying Guide: Choosing The Best Air Conditioner For A Windowless Garage
Selecting an air conditioner for a garage without windows requires specific considerations to ensure effective and convenient cooling.
Cooling Type and Ventilation Needs
- Portable Air Conditioners with Exhaust Hose: These units, such as BLACK+DECKER and SereneLife, require venting warm air outside, which can be done through a door or ventilation port. They typically cool larger areas and remove humidity but need an exhaust setup.
- Evaporative Coolers (Windowless): These cool air by evaporating water and do not need an exhaust hose, making them ideal for sealed garages with no window access. They work best in dry climates and smaller spaces.
Cooling Capacity and Garage Size
- Measure Your Space: Calculate your garage area in square feet. Portable AC units often specify the max area they cool efficiently.
- BTU Rating: Higher BTUs mean stronger cooling. For large garages, models like the BLACK+DECKER 10,000 BTU are suitable. Evaporative coolers usually perform better within smaller to medium spaces.
Humidity Control
- Dehumidifier Feature: Garages can get humid; ACs with built-in dehumidifiers help maintain comfort and reduce moisture-related issues such as mold and mildew.
- Evaporative Coolers Add Humidity: These actually increase humidity, so consider climate and ventilation before choosing.
Portability and Installation
- Ease of Movement: Wheel-equipped portable units allow transferring the AC between rooms or around the garage.
- Installation Complexity: Evaporative coolers are generally plug and play, while portable ACs needing exhaust require venting setup, which might be challenging in windowless garages.
Additional Features to Consider
- Remote Control and Timer: These allow convenience in adjusting settings without physically accessing the device.
- Filter Maintenance: Washable filters extend unit life and improve air quality.
- Ice Packs and Water Tanks: Evaporative coolers with refillable tanks and ice packs can enhance cooling efficiency and runtime.
By evaluating these factors, you can choose an air conditioner that fits your garage’s size, ventilation setup, and climate environment for effective cooling without needing a window.
