How to Choose Window Air Conditioner
Understand BTU Requirements
Choose a window air conditioner with enough BTUs for your garage size. For a 150 square foot space, look for at least 5,000 BTUs. Larger areas may need 8,000 BTUs or more to cool effectively.
Consider Energy Efficiency
Check the Energy Efficiency Ratio (EER) ratings. A higher EER means the unit uses less electricity for cooling. Look for models with EERs above 10 for better energy savings.
Noise Level Matters
Pay attention to the noise levels measured in decibels (dBA). Most models range from 52 to 60 dBA. Choose quieter units if noise is a concern, especially if you plan to work in the garage.
Look for Multi-Functionality
Find models that offer cooling, dehumidifying, and fan modes. This versatility can be helpful if you need to control humidity levels. Multi-functional units may save space and money.
Check Size Compatibility
Ensure the air conditioner fits your window size. Measure your window before purchasing. Most models come with installation kits, but a poor fit can lead to airflow issues.

Noise Levels
