Got an estimate to give. Residential house with A/C unit on a slope. theres a garden anchor wall there now 10 feet away 3 or 4 feet down that needs replacing. The soil beneath the A/C has eroded away from almost half of the unit. So What I'm going to do is fill in the area with aggreget compact in lifts redo the wall and all that good stuff. The question is How do I go about detaching the A/C unit. Should I find a contractor to do it or attemt it myself or try moving it a foot and filling hole and moving it back a foot and filling hole? Anyone do something like that. Ill probbly get pics tomorow.
