What is SEER/SEER2 and How Much Do They Matter?

A color-coded data table titled "Assumptions" that calculates estimated cooling costs based on 1150 cooling hours and a rate of $0.18 per kWh. The table compares different SEER2 ratings (ranging from 6 to 30) against unit sizes (ranging from 2.0 to 10.0 tons). Values are shaded in a gradient from green (lower cost) to red (higher cost).

In this installment, we will explain what are SEER and SEER2 AC ratings and provide a simple formula for determining your annual operating costs for air conditioning.  SEER stands for Seasonal Energy Efficiency Ratio. To calculate SEER, you simply divide Cooling output (in BTUs) by the total energy used in Watts. Let’s look at an […]
