Question I just bought a new house and I am getting some cement work done on the side of the house that has the ac unit. The contractor said that it would look better if we removed the unit and then put it back after they are done, they would make sure the area is level. I would like to remove the unit myself but I am not sure what's in the line going into the unit, it looks like a 1 inch cooper that is fully insulated.
Answer It would be somewhat costly to disconnect and move. The refrigerant has to be isolated in the unit providing the valves will hold and if not, the charge will have to be removed, after the slab is ready it will have to be set back, a vaccum pulled and the unit recharged. This will require two trips. I would suggest lifting the unit enough for the slab, place a couple of cement blocks on each side of the unit with long boards in between to hold the unit and let the slab be poured under the unit. The contractor will not want to do this close of work, but it is done quite often without having to remove the unit totally. Thanks J
