The energy efficiency of an air conditioning system is how effectively the AC takes electrical power and converts it into cooling power. The higher the efficiency of an AC, the less expensive it should be to run (provided that you had the system correctly sized and professionally installed in the first place).
But how do you know the energy efficiency of an air conditioner? You find out by looking at its SEER rating.
What Is SEER?
SEER stands for “seasonal energy efficiency ratio,” and it’s the ratio of the cooling power the system puts out (measured in BTUs) to the amount of electricity it draws (measured in watt-hours). This ratio is determined over the entire cooling season so to take into account variations in humidity and climate fluctuations. A similar rating, EER, measures efficiency per a single test under fixed conditions, and therefore isn’t as accurate a demonstration of how well an AC will serve you during the summer.
The higher SEER, the more efficient the system. The current ENERGY STAR certification requirements are 15 SEER for central air conditioning systems, so that’s a good lower rating to target when you’re shopping for an AC. There are many cooling systems that score higher than this. For example, variable-speed fan and compressor models can sometimes score 20–22, which can result in significant savings over each summer.
Make sure that you always work with skilled HVAC professionals for air conditioning installation: SEER won’t mean much if you end up with an oversized or undersized system that will have to work harder!
