Air Conditioner Service

Recently I had a new cable installed in a house I just moved into. TOT did the job. They had to drill a hole to complete the installation. I didn't notice until after they were  gone, but they didn't clean up the saw dust and dirt when they left. I had to go back to TOT for something. While I was there I asked them about not cleaning up. The service woman said it was not the responsibility of TOT to clean up after the work. Perhaps this is your answer.

@bill kip:  Actually, I'm asking for a recommendation for a service that doesn't make a mess, not an explanation for the reason some do make a mess.

I was only trying to be helpful!

We have four units which need regular maintenance and cleaning.  It is a dirty job even with the best equipment and the job is made more difficult if there is not enough room to work or too much furniture.  We use the same company but we don't always get the same guys, regardless, they always make an effort to cleanup but it is never enough and we have to cleanup after them.  I think you just have to accept a little cleaning up after they are gone.

Forget aircon , get fans. Much cheaper, and not such a shock when you go outside.
