Best Single-Zone Mini Splits
Every verified, priced single-zone system in our dataset - all sizes, all brands - in one table.

Use the BTU and coverage columns to narrow to your size class, then compare price against the heating rating and SEER2.

Buying notes
- Start from size, not price: find your BTU class in the sizing guide, then shop inside it.
- The cheapest systems in this table are flare-install (pro or equipped DIY); the true-DIY systems cluster at MRCOOL's prices.
- Two systems in the full dataset (Klimaire's DIY 12k and Hisense's Hi-EDGE) are verified but carry no price - see the homepage notes.
