Froze: total BTU is 21k. the sales person said each unit is 9k BTU. hmm... not sure how it will work out. I was told non-Inv condenser is make in Thailand. only inverter condenser is make in Japan. We went for Non-Inv cos most of the time, only 1 aircon is in use.
Donut: ya, the more we shop, the more blur n tired we got. initially, the sales person quoted us $1950, we just tried out luck and asked if there is any national day discount, and he quoted $1899. installation is this wednesday. hope they will do a good job.
