Introduction
Calculating the Seasonal Energy Efficiency Ratio (SEER) rating of an air conditioning system is crucial for assessing its energy efficiency over a typical cooling season. This calculation involves dividing the cooling output of the air conditioner over a typical season by the total electric energy input during the same period. Understanding the SEER rating helps homeowners and businesses in making informed decisions about their air conditioning systems, aiming to reduce energy consumption and lower utility costs.
This guide explores the vital components of SEER calculations, highlighting the type of data needed and the implications of different ratings. Furthermore, we'll delve into how using Sourcetable's AI-powered spreadsheet assistant facilitates these calculations and enhances data management.

How to Calculate SEER Rating
To calculate the Seasonal Energy Efficiency Ratio (SEER) for an air conditioner or heat pump, you need specific information about the unit's energy consumption and output. The SEER rating measures the efficiency of a unit over the typical cooling season, using Btu and watts to determine how efficiently the system uses energy.
Gathering Necessary Data
First, identify the cooling output in British Thermal Units (Btu) per hour and the electric input in watts per hour of the device. This information is often provided by the manufacturer and can be found on a yellow and black rating sticker, the air handler's information sheet, the building permit, or by directly contacting the manufacturer.
Performing the Calculation
The SEER rating is calculated by dividing the total cooling capacity by the total energy input. Specifically, multiply the Btu per hour by 1,000 to get the total Btu used during a season. Similarly, multiply the watts per hour by 1,000 to find the total watts used in a season. Finally, divide the total seasonal Btu by the total seasonal watts:SEER = (Btu per hour × 1,000) / (Watts per hour × 1,000).
This calculation allows you to determine the efficiency of your cooling system and ensure it meets the minimum SEER ratings required, which are 13 in northern states and 14 in southern states of the US, with an upcoming increase in 2023.
How to Calculate SEER Rating
The SEER (Seasonal Energy Efficiency Ratio) rating provides a measure of an air conditioning unit's efficiency over the cooling season. To determine this rating accurately, follow the straightforward calculation method described below.
Understanding SEER Rating Calculation
SEER rating evaluates how efficiently an air conditioner uses electricity. It's calculated by comparing the total cooling output over a season, measured in British Thermal Units (BTUs), with the total electric energy input, measured in watt-hours, during the same period.
Calculating the SEER Rating
Start by locating the BTUs per hour and the watts per hour of the cooling system. Multiply each of these by 1,000 to convert them into seasonal totals, considering that the average cooling season lasts approximately 1,000 hours, spanning late spring through summer.
Use the formula: SEER = (BTU per season) / (watts per season), where:
- BTU per season = BTU per hour × 1,000
- Watts per season = Watts per hour × 1,000
Divide the seasonal BTUs by the seasonal watts to find the SEER rating. This result gives a clear measure of the air conditioner's efficiency over the cooling season.
Why Calculate Your SEER Rating?
Knowing your system's SEER rating helps in assessing its energy consumption and overall efficiency. A higher SEER rating indicates greater efficiency, often leading to lower energy costs and environmental impact.

Calculating SEER Ratings: Practical Examples
Example 1: Basic SEER Calculation
To calculate the SEER (Seasonal Energy Efficiency Ratio) rating for an air conditioning unit, divide the cooling output of the unit over a typical cooling season by the total electrical input during the same period. For instance, if an AC unit has a cooling output of 15,000 kWh and consumes 1,200 kWh of electricity, the SEER rating would be calculated as SEER = 15000 / 1200 = 12.5.
Example 2: Adjusting for Climate Variability
Variations in climate can affect the SEER rating calculation. Consider an area with higher average temperatures. If the cooling output remains at 15,000 kWh but energy consumption rises to 1,400 kWh due to increased demand, the SEER rating is SEER = 15000 / 1400 ≈ 10.7.
Example 3: Impact of Maintenance on SEER
Regular maintenance impacts the SEER rating by optimizing performance and energy consumption. Suppose maintenance leads to a decrease in energy use from 1,200 kWh to 1,100 kWh, with cooling output unchanged. The new SEER rating would be SEER = 15000 / 1100 ≈ 13.6.
Example 4: Comparison After Component Upgrade
Replacing older components with more efficient ones can improve the SEER rating. For an AC unit that originally had a SEER rating of 10 (using 15,000 kWh of cooling output and 1,500 kWh of electrical consumption), and after upgrading components, the electrical consumption reduces to 1,250 kWh, the new SEER rating would be SEER = 15000 / 1250 = 12.
