Seasonal Energy Efficiency Ratio -

Specifically, SEER measures the total cooling output of an air conditioner during a typical cooling season, divided by the total electric energy input during the same period.

“And the 20?”

Think of SEER like the rating for your car. Just as a car with higher MPG goes further on a gallon of gas, an AC unit with a higher SEER rating provides more cooling using less electricity.

Note: A system is only as efficient as its installation. A high-SEER unit installed with poor ductwork or incorrect refrigerant charge will not perform at its rated efficiency. seasonal energy efficiency ratio

Regulatory updates in 2023 increased these baselines slightly, with the introduction of SEER2 ratings.

While often used interchangeably, SEER and are distinct metrics:

In the past, AC units often had ratings as low as 8 or 10. However, modern regulations have pushed efficiency much higher: Specifically, SEER measures the total cooling output of

The repairman, a weathered sage named Marco with a multimeter holstered to his belt, delivered the verdict. “Compressor’s shot. This unit is from 1992. It lived a good life.”

SEER is a ratio that compares the cooling output to the electrical energy consumed. Unlike the simpler Energy Efficiency Ratio (EER), which measures efficiency at a fixed peak temperature, SEER accounts for seasonal temperature fluctuations. : Measured in British Thermal Units (BTUs). Energy Input : Measured in watt-hours (Wh). The Formula : SEER vs. SEER2: What Changed?

As of , the industry moved to a new standard called SEER2 . Note: A system is only as efficient as its installation

She had saved compared to the same month the previous year.

Higher efficiency systems draw less power from the grid. If that power is generated by fossil fuels, a high-SEER unit directly results in lower carbon emissions.
