Currently, only seven air conditioners have been cleaned.
Of the remaining uncleaned air conditioners, two near the window can be cleaned only if the glass working platform is removed, since the maintenance staff could not step on it to clean them.
The air conditioner in seminar room 1 can only be cleaned after our company's signboard immediately above it is taken down.
Another one in seminar room 2, unfortunately, cannot be cleaned because there are too many ventilation vents and water pipes in the ceiling.
Lastly, the one over your seat has been out of order and can no longer be used. Water keeps dripping from it because the lamp tube made the position of the water pipe higher than normal, making water unable to run through the pipe, hence accumulating there and resulting in the dripping. Due to the renovation taking place, the ceiling could not be removed fully to inspect the interior.
Quotes of the replacement of the air conditioners at the reception and over your seat will be sent to you again, in case replacement is needed.
The maintenance company would send you a new invoice as only seven air conditioners were cleaned.
