Mini-splits HVAC

[trekrok]

I'm eyeballing these things for the whole house when my central finally gives it up. I really like the idea of being able to dial in each individual room (bedrooms especially) to a temp. What I don't really get is how this would heat and cool the smaller rooms in the house that wouldn't have an air handler. I wonder if there is some type of ventilation fan that circulates the air from the say living room to a bathroom?

I'm just having a hard time envisioning how it would work for the whole house. Anyone have any experience with them? They appear to be efficient, you get rid of the ducts, room by room zones and even the Mr. Cool DIY ones have a ceiling cassette option for the air handler now.

Any brainstorming fodder is appreciated.

Yeah, but you aren't putting an air handler in normal bathrooms and closets or for that matter in a breakfast nook off a kitchen, I don't think. Seems like there would have to be some type of cross room ventilation involved. Or these things simply don't make much sense for a fairly chopped up house.

Just make sure you caulk all those holes they drill to keep the mice and bugs out.

You are talking about the drain holes if they just go through the walls?

A mini split is no different than a regular system. Your electric and refrigerant lines go thru the wall, ceiling.

Yeah, on a multi-zone they'd all be going up into the attic and to the air handlers. The drains I'm not that excited about.

Absolutely mini splits don’t make sense for many applications
