Woohoo!! Thanks John, Leo and Jiabin for installing an air conditioner in my room. I called John and requested for a split system to be installed as I've sweltered enough summers in my west facing room. John also recommended Jiabin who was a very competent ventilation installer. I just had one condition, install the split system before those dreaded 40 degree days, within 2 weeks all 3 rock up and it was done within half a day! John also took me through what he was doing and explored the best options available, the best would have been to run the wire through the cavity wall through the roof and ceiling to the switchboard, that would have been a crazy amount of work but we worked out that he could link the split system to an existing switch in the room. I was worried that it may trip the system or worse, fry out the wires but was reassured by John and so far so good! They've got a saying, "do it once, do it good" these guys do exactly that, nothing dodgy or behind your back wiring that you'll have to worry about in the near future. Will definately recommend them to do any electrical works. You might even learn a thing or two too! Eg, John was giving a tutorial on voltage drop. *two thumbs up* keep up the good work!!!
