You know, it's so difficult to find a good company or a repair technician in our region. I had some problems with my AC as it refused to perform my commands. I contacted 2 companies (some of them are even posted above) to resolve this problem, but in the end, their so-called "pros" failed to identify the cause. But I still had to pay for their "work". Disgusting!
When I lived in Singapore it was easier to find a good AC/HVAC repair company. For example, I used
https://www.socool.sg/ services and they repaired my AC without any problems. Too bad that I can't return to Singapore now...
