What is a SEER Rating? How to Use it When Choosing the Right Heating Unit for Your Home

December 20, 2019

SEER stands for Seasonal Energy Efficiency Ratio. The SEER number is used to measure efficiency for air conditioners. The higher the number, the more efficient the equipment. Each state sets its own minimum standard SEER rating, and in Texas, that number is 14. You can use the SEER rating, along with other information, to make an informed choice about which equipment is right for you. Read on to learn more. How a SEER Rating Affects Your AC/Heating System Keep in mind that the SEER rating indicates the unit’s maximum potential. A unit might be rated at 21 SEER, but that doesn’t mean this level of performance can be achieved in all situations. The laws of thermodynamics apply, and various factors will reduce efficiency and performance. Factors that can impact how an AC system performs in the real world include outdoor temperatures, the size of and environment within the home to be cooled, thermostat settings and whether the system is properly maintained. In other words, a high SEER rating doesn’t automatically mean an AC unit will “pay for itself” compared to a less expensive model. When deciding which model to purchase, then, it’s important to consider other efficiency factors to help...
