I have had installed two new mini split LG inverter A.C. units recently.
LG makes dual inverter mini splits and also about the highest rated SEER unit at 25.5. SEER rating (a measure of a unit's efficiency) (https://en.wikipedia.org/wiki/Season...ficiency_ratio).
With that said, it would be hard to tell you about my electrical usage because each of my units are now on separate CFE meters. This lessens the chance of ever getting into the DAC rate. I have 6 CFE meters (6 separate bills) for my unit but am not sure that CFE still allows this.
I would think your decision could be based on how long you plan on keeping your unit, your A.C. usage and whether or not you rent it out.
And your 10 to 12 year old unit would not be very energy efficient, IMO. Time to replace it.
