How can you test the operation of a window?

The operation of a window can effectively be tested by checking if it opens and closes smoothly. This method directly assesses the functionality of the window mechanisms, such as the hinges, tracks, or sliding mechanisms. A window that operates smoothly indicates that it is in good working condition and that the hardware is functioning as intended, which is essential for proper ventilation, ease of use, and security.

Observing the color of a window does not provide any information regarding its operational state or mechanical parts. Measuring height is irrelevant to its operation; it serves a different purpose, such as verifying fit or compliance with building codes. Repairing visible cracks addresses issues concerning aesthetics or weatherproofing but does not demonstrate whether the window functions correctly. Focusing on the smooth operation ensures that all essential components are effectively engaged and performing as designed.
