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.
SEER Rating
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.
EER Rating
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.
