SEER stands for Seasonal Energy Efficiency Ratio, and it measures the annual energy consumption and efficiency of the unit’s cooling ability in typical day-to-day use. The higher the SEER value, the less energy the unit will use. Many older residential air conditioning systems in the U.S. may have a SEER number of 10 or less. The good news for homeowners in the market for a new air conditioner or heat pump is that current high-efficiency residential equipment can boast SEER values of 25 or higher. Higher SEER units typically cost less to run, which can save homeowners money on energy costs. Click Here to Read More *These are estimations, results will vary.
