I want to relocate an existing wall mounted AC from one wall to another within the same room. So I need to find a competent person/business that can do that for me. I am in PP, BKK2. Any recommendations?

I use these guys for servicing +855 17 440 023. The lads are punctual, reliable and competent and the business is run by a woman who runs a tight ship.

However, I used this guy for the installation.+855 97 296 6828. It was a few years ago, so hopefully he is still around. He's not the cheapest, but the only one who gave me accurate advice on my AC problem and got a messy job done properly, and I have had no problems ever since.

There are plenty of people who do the servicing, which is just cleaning the units without: breaking them; flooding the place, or electrocuting themselves. The top number passes all 3 tests.

Installations are a different beast and require the proper tools and staff for drilling holes in your walls, mounting brackets, power supply relocating, drainage etc. There's much more scope for things going badly wrong and you being left with the mess.
