Last week we had three of the seven air conditioners installed. We had planned on doing Inverters throughout the house to save on energy. We were told that the only inverter ACs that work with the existing piping (which was installed when the house was built a few years ago) are Daikin.

Just as we were about to purchase all of them, the salesperson told us for inverters to really be effective in saving on your electricity bill, they need to be running more than 3 hours at a time. We only plan to use the bedroom ACs and the Home Office ACs for that long at a time, so we checked with some more AC installers and they confirmed it. Two Daikin representatives from Selangor offered to drive to Seremban and explain their product to us, but when they arrived they along with the other installers where unable to tell us after what amount of usage time the inverters become cost effective... some said after three hours, some 5, 6 or 8. So R and I decided that we would buy the Daikin Single Split Inverters for our Master Bedroom and main Guest Bedroom and our office. We can save some money by buying regular York ACs for the other rooms. So the Installers arrived and after hours of work, the Daikin Inverter units were installed and giving more cool. York ACs are on their way.
