Minisplit install questions
I am building a new house and planning to install a couple of minisplits. The air handler locations are going to be approximately 20' away from the outside condenser and located on interior walls. I am planning on bringing drains to these locations but my question is what size conduit should I run under the slab to accommodate the copper lines and electrical. I would also like to rough in conduit for another potential mini split down the road so is 2" large enough or would 4" be more appropriate.
Also I don't like the look of the "chases" that are often run down exterior walls to accommodate the line sets on retrofits.With new construction installs, is it advisable to sleeve the line sets in conduit inside wall assemblies.
Any insight would be appreciated.
