2 I thought about drilling either 1 loop hole for 1 ton 250ft deep and circulating water with some sort of controller so the intake temp would first go through a radiator and cool down before it came across the coils of the mini split.
3rd way . Would be prob more expensive . But i have thought about doing earth tubes and letting the mini suck in the cooled air from the tubes.
4th way i thought about building a room with the well pumping water through a radiator in front of the mini.
Cutting the fittings and all are pretty much out of the question . I dont want to cut my new mini . I want . I guess you could call them (Bolt ons ) Easy to take off if i ever wanted to turn it back to stock.
Any of yall have any ideas on cheap ways to make the mini so it will be a bit more efficient?

There have been some discussions here about option number 2. as I recall, it has been successful.
But I agree with you, I don't think it would be a good idea to hack into your new mini.
But digging a hole, and building your own ground source heat pump air conditioner, now there's a good one.
I don't remember if you ever said how big your mini was, but if you could keep your eye out for a discarded air conditioner of may a one Ton size, and hack in and replace your condenser coil (the hot one) with some kind of heat exchanger (I really like brazed plate heat exchangers), and pump water from your bore hole loop through the new heat exchanger, you might really have something, even more efficient than your mini. A brazed plate heat exchanger wouldn't work very well for well water, you'd have to use a different HX.
