This is in reference to your mail yesterday on the above subject.
All the Carrier A/C units (indoor & outdoor units) have been serviced except those which are in the Watchman's area, those 5 A/C units will be serviced this afternoon.
As for the duct cleaning, the supplier they said they can't do it, but that they will try to find a subcontractor for this job.
However, we arranged a meeting with the mentioned Thoshiba supplier today at 3pm in the Beach Resort for inspecting the Thoshiba package units. Most likely they will do this job next week.
Please confirm the site access with me so that I can inform them accordingly.
Hope this works!
