Which AC Rating Should You Rely on When Buying a New System?

Of all the decisions you make as a homeowner, the most complicated one may be choosing a cooling system based on its AC rating for quality and energy efficiency. Since air conditioners last for years and the costs associated with home cooling will be among your highest, making a sound decision in this area is crucial.

Energy Efficiency Ratings

Central air conditioners have two ratings. The first is the seasonal energy efficiency ratio (SEER) and the second is the energy efficiency ratio (EER). Energy engineers determine the SEER by running each model of air conditioners and heat pumps they offer for an extended period. They measure how much electricity it takes to maintain 80 degrees Fahrenheit with a humidity level of 50%.

The measurement for the EER is similar, but instead of holding the outdoor air at 80, they hold it at 95 degrees Fahrenheit. The EER gives a good measurement of how well the air conditioner will perform at high temperatures. The SEER shows how efficiently the system runs during moderately warm temperatures over the cooling season.

Since this area has streaks of very hot weather, selecting a new system with a high EER AC rating makes financial sense. Most equipment that has a high SEER also has a high EER, although there are exceptions.

System upgrades to reach higher SEER and EER AC ratings may include equipment upgrades like variable-speed features. Not only do they provide better efficiency, they also increase your comfort. 

Brands Matter

Besides the quality of the parts and materials that go into air conditioners, the brand makes a difference. A handful of manufacturers lead the industry in quality, dependability, and durability, and the same is true with HVAC contractors. When choosing, insist on a licensed, bonded, and insured company with a solid local reputation.
