Snakes are generally not attracted to or likely to live inside hotel room AC/heater units. The internal components and structure of AC/heater systems do not provide suitable environments for snakes to thrive. Snakes typically prefer natural habitats, such as grasslands, forests, or underground burrows.
However, it's essential to note that any gaps or openings in the building structure, including around the AC/heater units, could potentially allow snakes or other pests to enter the room. This is why hotels and buildings typically have measures in place to prevent pests from entering, such as sealing gaps and conducting regular maintenance.
If you suspect the presence of a snake or any other unwanted wildlife in your hotel room, it's important to notify hotel staff immediately so that they can address the situation appropriately and ensure your safety and comfort. They can take appropriate measures to remove the snake and take steps to prevent future occurrences.
