Mini splits vs Central air

I'm curious and did a quick web search. It seems that an average or ballpark figure for a new 2 ton central AC is a draw of 11 amps. Please correct me if I am wrong. I don't know what unit i am interested in so cannot come up with a exact figure

A ballpark figure for mini splits is 5.7 amps for 12000 BTU and 4.4 amps for 9000 BTU. Giving a total of 10.1 amps for 21000 BTU.

It would appear that 2 mini splits would be slightly more efficient than a central air. Is my theory right or am I way off base??

Ideas, thoughts, wisecracks and advice greatly appreciated.

A couple of things to also consider...

Are your mini splits going to need condensate pumps to drain?

Do you have ducting in place now?

I have ducting in place now. The general consensus is it is too small and needs to be replaced. 2 ton unit with a 10X10 inside dimension main supply duct. Same for the return.

Condensate pump!! That would solve one issue.

Thanks for the response JIm

A condensate pump would add to your amperage and would not be as quiet. It would require regular cleaning.

Ductwork is expensive and yours sounds too small.

A standard split system is more likely to get repaired in an emergency beeper call.
