Seer rating is often used to describe different types of HVAC equipment, but what does it actually mean? It stands for the Seasonal Energy Efficiency Rating. Different brands of equipment test out their products at their factories to ensure they meet the standard of the SEER ratings before they are distributed to wholesalers. To a consumer it can feel like a misrepresentation because the units are tested for average temperatures not at extreme temperatures like we see in Phoenix, AZ. Its critical when choosing what the right system for your home to understand all the facts regarding seer rating as well as functionality of different types of equipment. Some examples are single stage, two stage, and variable speed. Seer rating will change again at the end of 2022. Currently in Arizona the minimum is 14 seer, however equipment can go all the way to 25 SEER. Sometimes its not just about price shopping its about the value of the equipment and more importantly the quality of the installation. Seer rating and types of equipment are a valuable piece of information as well.
