How Does SEER Affect Your Cooling Costs?

SEER Seasonal Energy Efficiency Ratio is a numerical value that represents the efficiency of an air conditioning system. It measures how effectively the unit converts electricity into cooling output over the course of a typical cooling season. Higher SEER ratings indicate greater energy efficiency.

Why SEER Matters

SEER matters because it directly affects your energy consumption and, consequently, your utility bills. A higher seasonal energy efficiency ratio rating means your air conditioner can provide the same level of cooling with less electricity, saving you money and reducing your environmental impact.

How SEER Is Calculated

SEER, or seasonal energy efficiency ratio, is a critical metric for evaluating the efficiency of air conditioning systems. But how exactly is the seasonal energy efficiency ratio calculated, and what does it reveal about an AC unit’s performance? In this blog, we’ll take a closer look at the science behind seasonal energy efficiency ratio calculations to help you better understand this essential aspect of air conditioner efficiency.

The Basic SEER Formula

At its core, SEER is a ratio that measures how efficiently an air conditioner converts electrical energy into cooling power. The formula for calculating the seasonal energy efficiency ratio is relatively straightforward:

SEER = Total Cooling Output (in BTUs) / Total Energy Consumption (in watt-hours)

Let’s break down each component of this formula:

1. Total Cooling Output (in BTUs)

The numerator of the seasonal energy efficiency ratio equation represents the total amount of cooling provided by the air conditioner over the course of a typical cooling season. This cooling output is measured in BTUs, or British Thermal Units, which quantify the amount of heat energy removed from the indoor air.

To determine the total cooling output, the air conditioner’s performance is assessed under various temperature conditions that mimic real-world usage. These conditions typically include different indoor and outdoor temperatures to simulate the changing demands on the system throughout the cooling season.

2. Total Energy Consumption (in watt-hours)

The denominator of the seasonal energy efficiency ratio equation accounts for the total energy consumed by the air conditioner during the same cooling season. This energy consumption is measured in watt-hours, reflecting the electricity used to operate the system.

To calculate the total energy consumption, the air conditioner’s power draw is monitored over the entire cooling season. This measurement takes into account the unit’s electrical efficiency, including any variations in energy usage as the temperature changes.

SEER vs. EER: What’s the Difference?

When you’re in the market for a new air conditioner, you’ll encounter various efficiency ratings, with two of the most common being SEER and EER. These acronyms represent important metrics that assess an air conditioner’s performance, but they do so in slightly different ways. In this article, we’ll explore the key distinctions between SEER (Seasonal Energy Efficiency Ratio) and EER (Energy Efficiency Ratio) to help you make an informed decision when choosing the right cooling system for your needs.
