14 SEER Mini Split

14 SEER is considered good efficiency, meeting the minimum standard for most regions.

SEER2 is a new testing method that typically results in lower ratings. 14 SEER2 is roughly equivalent to 15 SEER.

A 14 SEER AC unit typically costs between $3,000 to $6,000, including installation.

In 2024, the minimum SEER rating will be 14 SEER in Northern states and 15 SEER in Southern states.

SEER doesn't determine tonnage. Tonnage relates to cooling capacity, while SEER indicates efficiency.

As of 2023, the lowest allowed SEER rating is 13 in Northern states and 14 in Southern states.

Energy use varies, but a 14 SEER unit uses about 29% less energy than a 10 SEER unit.

For central ACs, 15 SEER or higher qualifies for Energy Star in the North, 15.2 SEER in the South.

For mini splits, a SEER rating of 20 or higher is considered good.

For 2024 tax credits, ACs need to meet the highest efficiency tier set by the Consortium for Energy Efficiency.
