A lot of assumptions about cost savings from 5 vs 2 tick. Use this calculator. There's another nea link, can't find it now. But it's useful.

There's been much talk about the mitsubishi 5 tick being lousier (lower powered) than the 2 tick because it's 6.6 kW vs 7.52 kW. Find it hard to believe the japanese mitsubishi engineers are as incompetent as people seem to suggest. I doubt it's that simple. Could very well be the 5 tick having a more efficient design and cooling just as well, but using less power.

Assuming air con lasts for 7 years with heavy usage (8 hours daily), system 4 mitsubishi 5 tick (4G28) vs 2 tick (4A28). 5 tick saves $3000

Do your own calculations here:

More info here:

If you use the air con for at least 8 hours daily, 5 ticks will surely save you a ton of money across the years.

I doubt many will on all aircon with that amount of load every for 7 to 8 hours. Hence, the savings shown are not as representative as it should be.
