waterdischarge

I also looking for servicing companines....i called back my installer company they quoted $35 per fan coil. Then read the classified..some companies doing it for $20. Dun know what is the difference. I also tried calling some other companies on http://singapore-aircon.blogspot.com they quoted around the same range also. WHy is there a price difference when they all mentioned the general service will be the same?

I do not think HDB can install ceiling cassette. Anyway, you can trying emailing this guy from http://singapore-aircon.blogspot.com He seems to be quite knowledgable in aircon.
