We aim to help our customers save money while enjoying comfort. We put it in our slogan: \u201cLive Green, Save Green.\u201d One of the ways to save money while helping the environment is to invest in HVAC equipment with improved energy efficiency. The more efficient a device, the less energy it consumes to provide comfortable temperatures for a household. There\u2019s also less energy taken from power plants, which helps everyone to live greener.<\/p>\n\n\n\n

This is why we encourage looking into high-efficiency air conditioning in Modesto, CA<\/a>. We\u2019re going to examine the efficiency ratings of modern air conditioning systems and what they mean\u2014as well as how to ensure they make a difference for you, since a high-efficiency rating isn\u2019t a guarantee of savings, although it puts you on the right path.<\/p>\n\n\n\n\n\n\n\n

EER and SEER: The Two Basic Efficiency Ratings<\/h2>\n\n\n\n

Air conditioning systems have two efficiency ratings you will see listed, often prominently: energy efficiency rating<\/em> (EER) and seasonal energy efficiency rating<\/em> (SEER). They\u2019re different by only one word because they use almost identical methods to measure how efficiently an air conditioner converts electrical power into cooling power.<\/p>\n\n\n\n

EER is a ratio of the amount of cooling power (in British Thermal Units, or BTUs, removed from the air) the AC provides to the amount of electricity (in watt-hours) consumed as tested under specific conditions. The higher the EER rating, the more efficient the unit can perform.<\/p>\n\n\n\n

SEER is the same ratio of cooling power to electricity. The difference\nis how it\u2019s measured. Where EER is done as a single test under one set of\ntemperature and humidity conditions, SEER is the average of multiple tests done\nwith a range of temperatures and humidity conditions. These tests are designed\nto imitate an entire season of cooling to give the consumer a sense of the\noverall summer performance of the air conditioner. SEER is always higher than\nEER.<\/p>\n\n\n\n

What to Look for in These Ratings<\/h2>\n\n\n\n

\u201cWhat\u2019s a good SEER\/EER rating?\u201d is probably the big question\nyou have now. The easy answer is that you should only look for AC systems with\nSEER\/EER high enough for the system to qualify for the US Department of Energy\u2019s\nENERGY STAR label. The current ENERGY STAR requirements are SEER\/EER of 15\/10\nor higher. Special high-efficiency systems score higher than this, but they\nalso cost more. We can help you with finding the right efficiency to meet your\nneeds and budget.<\/p>\n\n\n\n

A Caution About Efficiency Ratings<\/h2>\n\n\n\n

Saving energy is about more than picking the highest SEER\/EER rating you can find and then calling it a day. These efficiency ratings are the \u00admaximum performance from an air conditioner\u2014they don\u2019t mean a system will perform that well all the time. If you have a bad installation from amateurs or an air conditioner that isn\u2019t sized correctly for your house, the AC won\u2019t perform at the efficiency you want. SEER\/EER are important, but they aren\u2019t the final word on energy efficiency. Let us help you receive the best when it comes to choosing a unit and installing it.<\/p>\n\n\n\n
