Convert SEER to SEER2

What is SEER and SEER2?

SEER (Seasonal Energy Efficiency Ratio) measures the cooling efficiency of air conditioners and heat pumps over a typical cooling season. SEER2 is a new standard introduced in 2023, which uses the same formula but under different test conditions to better reflect real-world performance.

Formula

The formula to convert SEER to SEER2 is:

\[ \text{SEER2} = \text{SEER} \times 0.955 \]

Example Calculation

Consider an air conditioner with a SEER rating of 15:

Using the formula:

\[ \text{SEER2} = 15 \times 0.955 = 14.33 \]

This means the SEER2 rating is 14.33.
