There are many ways to save money (just ask ChristianPFC), but servicing my own air conditioners? Thank you, but I'll pass on that one. I don't need to save 1800 baht that badly.
My air conditioners are placed near the ceiling. I'm not about to be climbing ladders, trying to figure out what to take apart and how to take it apart, followed by trying to figure out how to put Humpty Dumpty together again - along with risking a ladder accident, potentially seriously harming or even killing myself.
I prefer to hire experienced professionals who know what they're doing and show up with the right equipment to do it with. Considering this time one of my air conditioners needed Freon, I don't have a gauge to check that, would have no idea how or where to hook it up if I had one, and have no idea where to buy Freon or how to inject it in. Without professional service, I probably would have failed to figure out that I even needed any Freon.
I fully trust K.J. Aircon. They installed my air conditioners and they take good, reliable, honest, competent care of them at quite reasonable and acceptable prices.
Since you mentioned cars, mine is a Toyota. I have my car serviced at the Toyota dealership. I have never been dissatisfied with their service or prices. I'm not a mechanic. At my age, I have no desire to try to learn how to be one.
Even if I was interested, I would at least have to take some kind of auto mechanic and air conditioning maintenance training courses to have even a clue what I'm doing. You don't pick that up watching Sesame Street.
I like to save money too, when I can. Professional services are among the kinds of things I'm saving the money for . . .
