aircon inverter vs non inverter

Hi Member's

So as per the heading i am stuck with the decision over the two type's.

I am looking for a 24000BTU and a 12000BTU.

So far i have been looking at just Samsung but open to other GOOD Brand's.

Samsung Max Non-Inverter R22 (AQ) Model Line
24000BTU R7979
18000BTU R6839
12000BTU R4320
9000BTU R3875

Samsung Inverter Light R410-A (AR) Model Line
24000BTU R9799
18000BTU R8431
12000BTU R5233
9000BTU R4549

I will be using them mostly for Cooling and Not Heating and will only need them for +-5Years.

There is a R2733 Difference and an additionally R2000 cost for installation.

Is the price difference worth it?

I was planning on buying the 24000BTU Non-Inverter for the Living Are +-50sq and the 12000BTU Inverter for the Bedroom +-30sq

What are your views on this?

Thanks
