Best Mini Splits Under $1,500
Every verified system in our dataset under $1,500 of equipment cost. This is value-brand territory - Senville, Pioneer, Cooper & Hunter, Klimaire, TOSOT, and one premium-brand outlier (LG's 12k) - and none of it is true DIY: at this price, every system is a flare install for a pro or an equipped homeowner. What the money does buy, at the top of this table, is real cold-climate heat: the dataset's efficiency leader sits at $1,399.99 and heats to -22F.

Buying notes
- Equipment price is not project price: budget $1,000-2,500 per zone for professional installation, or the tool kit for a flare DIY install.
- The $659 entry's efficiency figure is unpublished here - its retailer page contradicts itself on SEER2, and we don't guess.
- Under-$1,500 systems skew small; only the 24k value entries here cover 1,000+ sq ft.
