Compact, mid-capacity and large mini-split heat pumps compared on the official ENERGY STAR record, not the brochure claim.
Official SEER2, official HSPF2, official EER2 and official COP at 5°F. SplitPick reads the ENERGY STAR certified mini-split heat pump dataset and ranks systems with the weights printed on every page. 3 categories, 175 products, 33 head-to-heads.

How it works
1. The official ENERGY STAR record
Every scored figure comes from the ENERGY STAR certified mini-split heat pump dataset, linked on the product card. If a figure is not published we show "Not listed" and score it at the category minimum, so an unpublished number never outranks a published one. Official ratings are for the certified outdoor and indoor combination shown.
2. Different capacities, the same official fields
Compact systems at 12,000 Btu/h or less of official cooling capacity, mid-capacity systems from 12,001 to 24,000 Btu/h, and larger official capacities above 24,000 Btu/h are each ranked in their own table so official size does not dominate the score. All three use official SEER2, official HSPF2, official EER2 and official COP at 5°F. Rebadged official model numbers with identical scored fields share one page.
3. Match it to the room and the refrigerant
A high official SEER2 is not automatically the right system for a small bedroom or a cold-climate house. Official cooling and heating capacities, official COP at 5°F and the official cold-climate flag help you shortlist. Use a licensed, EPA Section 608 certified HVAC technician for the refrigerant and electrical work — several official refrigerants here are mildly flammable (A2L). Then check the price on Amazon. Commissions never change the order.
