Understanding EER

[Aircol]

I'm trying to understand how much savings there is with every increase in an EER. For example, if I go from an 11 EER unit to a 12 EER unit, how can I translate that into a % in terms of savings?

I'm trying to understand how much savings there is with every increase in an EER.

For example, if I go from an 11 EER unit to a 12 EER unit,
how can I translate that into a % in terms of savings?

11 to 12 __ ~ 9% in general
12 to 13 __ ~ 8%

Actual location and equipment specifications are necessary
to determine the average time-weighted C.O.P. and
review Manufacturer's EXTENDED PERFORMANCE DATA
along with weather conditions.
