Narrative:

During cockpit preflight; it was noticed that the carpet on the floor of the aft portion of the cockpit was completely covering two floor vents. It was obvious that this installation was incorrect; as the vents were completely covered by the carpet. The mechanic working the flight was notified of this; and he agreed that this was not right. He contacted maintenance control and then proceeded to cut holes in the carpet in order to allow proper airflow through the vents. We then accepted the aircraft and were able to depart on time. When the carpet was installed; the vents were covered. The installers neglected to cut holes in the carpet to accommodate the vents. Whoever inspected the aircraft after the carpet was installed also failed to notice that the vents were covered. No company mechanic ever noticed the problem; nor did any previous flight crew. Finding something like this does not fall under the normal cockpit preflight duties. Better quality control of these types of maintenance procedures is required.
