Aircon installer was here this morning for an ocular. He tried to dissuade me from upgrading the drain line from the standard 3/4" to 1" as suggested on this thread. Makapal daw and mahirap ibalot etc etc. He finally relented when I stood firm. The line will extend 22' from the front wall of the garage to the gate.

We may also need to upgrade from a 2.5 to a 3.0 based on the area and usage (living room + kitchen + small bathroom + stairs). We decided on a Panasonic but since we might be getting a bigger unit we will have to check their prices again. They recommend Daikin and Panasonic in terms of reliability. They also carry LG and Hitachi.

If all goes well everything should be up and running by this weekend
