What is a SEER rating?

A SEER rating, or Seasonal Energy Efficiency Ratio, is a crucial measurement used to gauge the efficiency of cooling systems, specifically air conditioners and heat pumps. It represents the total cooling output (measured in BTUs) provided by a unit over a typical cooling season, divided by the total energy input (measured in watt-hours) consumed during that same period.

The significance of the SEER rating is that it allows consumers and professionals to evaluate and compare the energy efficiency of different systems. A higher SEER rating indicates a more energy-efficient unit, which can lead to lower energy bills and a reduced environmental impact due to decreased energy consumption.

Understanding the SEER rating is essential for making informed decisions regarding HVAC systems, especially for residential and light commercial applications. This metric directly relates to the performance and operating costs of air conditioning systems and is a key factor to consider when purchasing or recommending equipment.
