Conduit for Future Mini-split Indoor Unit?

Hi everyone, I'm currently replacing the drywall in a room that could very likely get a mini-split down the road. The little I know about them is that it would need a condensate line, a refrigerant line, and an electrical line. I'm wondering if it's possible to either run those lines now (i.e. are they pretty universal or you don't know till you know what brand and size you're going with) or if it's possible to at least leave a conduit for the refrigerant line and electrical line and just go ahead and run the condensate line in any case. I frankly have never worked with them and don't know if running a refrigerant line through a conduit would be darn near impossible, but figured it's worth asking. If it is possible, then what size conduit would you suggest? Assume the condensate line would be outside the conduit and it would just be the refrigerant and electrical lines inside.

Thinking about stuff like this is what makes my projects take twice as long as expected. Thanks for your help.

 

When dealing with copper lines.... it's almost impossible to snake them in a wall or thru a tubing in the wall. The line set is sized to the unit so running it ahead of time can be risky. Typically the lines are run directly thru the wall and contained in an enclosure/conduit down the outside of the house. Running the drain line in the wall wouldn't be of much benefit in the grand scheme of the installation.

 

I agree with Pete, for mini spilts, it's usually not worth planning ahead unless you know exactly what you'll be installing. It's also difficult to get the correct bend in the refrigerant lines when going into the wall.

Most installations can be made with no raceways inside the house.

If you're really interested, they have rough-in boxes. I've never used one (nor know nothing about this company), but here's an example:
