Buying Guide for Window Air Conditioners for Garages

When selecting the best window air conditioner for your garage, consider the following key factors to ensure optimal comfort, efficiency, and usability:

Cooling Capacity (BTU)

Measure the size of your garage in square feet. A general guideline is 20 BTU per square foot of space. Small garages under 150 sq ft can use 5,000 BTU units, while larger garages might require between 10,000 and 14,000 BTU, depending on insulation and sun exposure.

Installation Type and Portability

Window-mounted units are typically fixed but provide efficient cooling. Portable air conditioners offer flexibility and can be moved and stored as needed but require venting through a window. Choose based on your garage layout and whether permanent installation is feasible.

Noise Levels

Garages functioning as workshops or hobby spaces benefit from quieter units (under 55 dB). Check noise ratings to avoid disturbance, especially if you spend long hours in your garage.

Energy Efficiency

Look for models with good CEER (Combined Energy Efficiency Ratio) ratings to reduce electricity consumption. Energy-efficient models help lower operating costs, which is important for units running during hot seasons.

Additional Features

  • Smart controls and remote operation: Provide convenience for adjusting settings remotely.
  • Dehumidifier function: Useful for reducing moisture and preventing mold in damp garages.
  • Washable or reusable filters: Ease of maintenance improves long-term performance.
  • Auto-restart and sleep modes: Enhance usability during power outages and nighttime cooling.

Refrigerant Type

Eco-friendly refrigerants like R32 or R410A reduce environmental impact and can improve energy efficiency compared to older refrigerants.

Size and Venting Requirements

Ensure the unit fits your garage window dimensions or space. Portable units need window kits for exhaust venting, so plan installation locations accordingly.
