Does where you live change which mini split to buy?
Short answer: Where you live changes four things about a mini split: how hard it works to heat, how many hours it cools, what your power costs, and which rebates you can get. The size you need still comes from the room. Pick your state on the map or in the list below.

What stays the same everywhere
Every MRCOOL DIY system uses a pre-charged Quick Connect line set, so there’s no vacuum pump or refrigerant work, and the size still comes from the room: measure length × width and use the sizing guide. Shipping is free to the 48 contiguous states.
Mini split questions by state
Do you ship to my state?
Shipping is free to physical street addresses in the 48 contiguous United States. Hawaii and Alaska ship by quote: ask us for a quote first, and it has to be approved and paid before we ship.
Does my climate change the size I need?
Not the chart. It changes which end of a size range you land on: go one size up for rooms with west or south windows, a top floor, high ceilings or poor insulation.
Will a mini split heat my home in a cold state?
DIY EasyPro and DIY 5th Gen keep heating down to −13°F outside, and the DIY 5th Gen 55K multi-zone down to −22°F. Below that, keep a backup heat source for the coldest nights.
