Cooling programs can fall into three classes based mostly on SEER:

·        Mid-efficiency: 16-18 SEER

·        Excessive effectivity: 20+ SEER

Nationwide SEER Requirements

The U.S. Division of Vitality (DOE) requires fashionable cooling programs to be at the very least 13 SEER, however your state might have elevated necessities.

In northern states, the DOE requires air conditioners manufactured in 2015 or later to be a minimal of 13 SEER. However in southern states, the DOE requires air conditioners put in in 2015 or later to be a minimal of 14 SEER.

What’s the Distinction Between SEER And EER?

An Vitality Effectivity Ratio (EER) ranking measures the effectivity of room air conditioners, normally smaller, window-mounted air conditioners.

To calculate an EER ranking, producers divide a system’s cooling output by its energy enter. Like SEER, the upper the EER ranking, the extra environment friendly the system will be.

EER scores are extra fixed as a result of they don’t consider a variety of seasonal temperatures like SEER scores do.

Of the 2, SEER scores are used extra ceaselessly to attain effectivity.
