Where and how you install your compressor can absolutely make a difference in performance. If you are running a compressor that is vented and not sealed, you want to make sure to install it in a place that is as dry and free of dirt and debris. Since they're not fully sealed, moisture and dirt can be absorbed through the intake and get into internal components and damage the compressor. If you have a sealed compressor, you just want to make sure to install in an upright position so it can properly disperse heat.
