A SEER rating is a numerical value (from 13 to 25) that represents the total cooling output of a heat pump during a typical cooling season, divided by the total electric energy input. The higher the SEER rating, the more efficient the heat pump.
The rating is a ratio of the total cooling output (measured in BTUs) divided by the total electric energy input (measured in watt-hours) during the same period. The Difference Between SEER and SEER2 seer ratings for heat pumps
The "right" rating depends largely on your climate and how long you plan to stay in your home. A SEER rating is a numerical value (from
SEER2 ratings are typically about 4.5% lower than the old SEER ratings for the same unit, but they are a much more accurate representation of actual performance. What is a "Good" SEER Rating? The Difference Between SEER and SEER2 The "right"
is a measure of cooling output divided by electric input over a typical summer. Higher SEER (16–20+) is great for hot climates like Florida or Texas.
