Well i got kenwood both 18s and 1803s installed and both of them consume same amount of electricity. I think it just a market gimmick of kenwood trying to make fool of people saying that 1803 can save upto 60% and 1804% can save upto 75%.
The ones i got are totally identical not a screw is different.
18s was bought for 65k with home delivery and installation, 1803 was bought for 59.5k with home delivery and installation was done separately.
1 thing to all the people installing dc inverter ac's .
Its gas R410a is not expensive u can have complete gas for 2500 rupees by weight same can be chkd by alkaram square in karachi or area where u can find ac parts in your respective cities.
Ac technicians are making fool out of people saying its gas is very expensive even asking 8k rupees for just a gas charge. Just be carefull not to fall in trap.
