Hi all, first time out so be a little tolerant. I am looking out my window at a 10+ year old ac compressor that really needs replacing. The existing location is terrible as it is in a front courtyard, viewable from the street and within a few feet of the front entrance. I would like to move it to the side yard on the east side of the house. Since the house is build on a slab and I don't have an attic on that side I though that the easiest/best method would be to run the wires and pipes underground through (2) 3/4" conduits and a 2 or 3 inch abs pipe for the refrigerant lines. The total distance underground is less than 50' and about 10' to the air handler. As I am retired and on a limited budget I would do the digging (which oddly enough I don't mind, actually enjoy) and maybe even pull the wires. Is this (going underground) a stupid idea??? Thanks in advance, G

It is not a good idea and the whole job would be VERY expensive to do. It may take 4-6 hrs plus freon, nitrogen test, copper tubing etc etc. My company would charge $600 to $1000 plus taxes to do it. It is not easy to bend large freon lines tightly and if you have elbows soldered in, it takes more time and there is a chance for leaks.

The lines would need a lot of insulation.
And the pipe the lines are ran through, would need to be sealed to keep water out.

I can be done. But, you can lose capacity. And care must be taked to prevent refrigerant migration and oil slugging.

New high eff units are quite, you should consider installing one in the same location with scalloped cinder block wall around it leaving enough room for service and air flow.
