They have to be big enough to cool room easily so they can run at lower speeds to get better efficiency however they are only about 30% more efficient so if your mate is spending $30 a month a non inverter model would cost $40 a month. If the cost difference is about $200 then it would take over one and a half years to get the extra cost back.
I run a 2HP non inverter aircon in 104 10 hours a day, it runs constantly and costs about $100 month to run. If I had an inverter model my bill might be about $105 month
Yeah, i figure it has more to do with being a new 2012 1HP model...
