Understanding Air Conditioner Energy Efficiency
When it comes to air conditioners, energy efficiency is a critical factor in determining how much electricity your unit consumes. There are two primary ratings used to measure AC energy efficiency: SEER and EER.
The Seasonal Energy Efficiency Ratio (SEER) measures an air conditioner’s efficiency over an entire season. It’s calculated by dividing the unit’s cooling output by the energy consumed in watt-hours. The higher the SEER rating, the more energy-efficient the AC unit is.
For units sold in the United States, the minimum SEER rating is 13. However, more efficient models can have SEER ratings as high as 25. Upgrading to a higher SEER unit can result in significant energy savings over time.
The Energy Efficiency Ratio (EER) is another rating used to measure AC energy efficiency. Unlike SEER, EER measures efficiency at a specific temperature rather than over a season. It’s calculated by dividing the cooling output by the energy consumed in watt-hours at a set outdoor temperature.
The higher the EER rating, the more efficient the AC unit is at that particular temperature. EER ratings can range from 8 to 12 for most units, with higher ratings indicating better efficiency.
When shopping for a new air conditioner, pay attention to both SEER and EER ratings to ensure you choose an efficient model that will help keep your energy bills low.

Regular air filter maintenance is essential to ensure optimal air conditioner performance. Dirty filters can restrict airflow, causing the AC unit to work harder and consume more energy. Clean or replace your air filter every one to three months to improve indoor air quality and prolong the lifespan of your air conditioner.
Calculating Air Conditioner Electricity Consumption
Understanding the electricity consumption of your air conditioner can help you make informed decisions on reducing your energy bills. To calculate the energy usage of your AC unit, you need to know its wattage and the amount of time it runs.
The wattage of an air conditioner is usually labeled on the unit itself or in the owner’s manual. It can range from 500 watts to 3500 watts or more, depending on the AC’s size and type. If you can’t find the wattage label, you can also use a wattage meter to measure the AC’s power consumption.
Once you know the AC’s wattage, you can calculate its energy usage in kilowatt-hours (kWh) by multiplying the wattage by the number of hours the unit runs. For example, if your 1500-watt air conditioner runs for 8 hours a day, its daily energy consumption is 1500 x 8 = 12000 watt-hours or 12 kWh.
It’s important to note that other factors, such as the temperature setting and the cooling load of your space, can also affect the AC’s electricity usage. However, calculating the basic energy consumption of your air conditioner is a good starting point for understanding how much electricity it uses.
