Which of the following types of coolers requires no permanent construction removal for maintenance?

Walk-in coolers
Residential air conditioners
Window air conditioners
Portable coolers

The correct answer is: Walk-in coolers

The type of cooler that requires no permanent construction removal for maintenance is a portable cooler. This type of cooler is designed to be easily movable, which allows for convenient access to its components for maintenance without the need for any structural alterations. Portable coolers are typically used in various applications and environments where temporary cooling is desired, making them user-friendly when it comes to upkeep. In contrast, walk-in coolers, residential air conditioners, and window air conditioners often involve more complex installations that are integrated into the building's structure. These systems may require removing fixtures or construction elements in order to access components for maintenance or repair, making them less convenient compared to portable options.
