Dear Nax,
Thanks for Yr post, feedback and compliment too. For the arrival timing, yes I usually always give a time range of when my Specialist will arrive. For the evening time slot, it's usually between 7 to 8pm. This is because, due to the nature of the job and a possible wide variety of problems that may be faced by the earlier customers, it's rather hard to pinpoint the actual timing of when he can really reach for the next customers. So, we always give a time range of arrival, and provided no run-over of the schedule which we would inform, he will come within the pre-arranged time slot range.
Yes, the compressor cleaning is not usually done in the evening (when Yr neighbors are also home from work). This is since we need to ensure that the cleaning will not affect nor disturb all the other units below. In the day time (during office hours), my Specialist comes with his assistant, whom then can assist him in informing all the neighbors. And don't worry, even in a rare case when somehow he comes by himself, my Specialist is the one who will go down to inform Yr neighbors so as to make sure that the compressor cleaning won't affect them. This is one of the reasons why there's a difference in price between medium and higher floors. Another is being the possibility of cleaning needed if somehow the below units are inadvertently affected. In July this year, the difference starts on above 15th level. Yet, my sincere apologies that I've been unable to timely update my website due to my being overseas from early this month. Nevertheless, my Specialist always clearly inform/quote the price in advance before any cleanings ever done, and with no hidden cost afterward.
Yes, my Dear, as I always say to all other Mummies, do always contact/SMS/email me regarding Yr appointments to keep me in the loop. This is because my Specialist is already very occupied in the field practically for the whole day. Hence, some records he may miss. So do contact me and keep me in the loop for all follow-up arrangements so that I can help arrange the best time slot for You and monitor his schedule too.
Glad to know that you are happy with my Specialist's workmanship on Yr cleaned unit. And don't worry, he will come with his assistant during the day time for Yr compressor cleaning. I will PM you regarding Yr next time slot in the afternoon for Yr compressor cleaning ya my Dear.
Thanks and have a good weekend!
