Notes:

• Efficiency Listings are organized by CEE category and sorted in descending order of efficiency.
• CEE categories with a VERY large number of conforming models have been subdivided by capacity range.
• Tier I models are distinguished by an orange background and italic lettering. Tier II listings appear in a green background.
• For Split-System categories under 65 MBtuh, which have a large number of conforming models:
  • Listings are limited to the highest-sales-volume condensing unit / coil combination for each condensing unit model.
  • Where the highest-sales-volume combination does not meet the CEE specifications, but another combination does, the least efficient conforming combination for that condensing unit is listed instead.
  • These listings are indicated with an asterisk (*).
