Understanding Energy Efficiency Ratings
When delving into the realm of energy-efficient air conditioning, understanding the various efficiency ratings is crucial. These ratings, such as EER, CEER, and SEER, are not just arbitrary numbers; they are key indicators of how well an air conditioner performs in different conditions and how much it might cost you in the long run. Let’s break down these ratings to help you make a more informed choice.
Decoding EER and CEER
- Energy Efficiency Ratio (EER): This rating measures the efficiency of an air conditioner when the outdoor temperature is at a specific level, typically 95°F. It’s calculated by dividing the cooling capacity (in BTUs per hour) by the power input (in watts). A higher EER rating means better energy efficiency, especially during the peak of summer.
- Combined Energy Efficiency Ratio (CEER): An evolution of the EER, the CEER includes the energy consumed while the unit is in standby mode. This gives a more comprehensive view of the unit’s overall energy efficiency, making it a crucial metric for those looking to minimize their environmental impact and energy bills.
