The correct answer is the evaporative cooler, as it is designed for ease of service and maintenance. Evaporative coolers are typically installed in a way that allows for straightforward access to components such as pads, motors, and fans without requiring the disassembly of surrounding structures. This easy access is crucial for regular maintenance tasks, such as cleaning and replacing pads or ensuring the water distribution system operates effectively.

In contrast, swamp coolers and refrigerated coolers might have specific configurations or housings that can complicate access, necessitating more extensive disassembly in some cases. Ice coolers also might not inherently prioritize service access in their design and may require structural adjustments or removal to access necessary components efficiently. Therefore, for maintenance and serviceability, evaporative coolers are the preferred choice that meets the requirement of having service access without removing any surrounding structure.
