Some heating and air conditioning terms can seem intimidating to people new to the industry. For instance, many companies brag about SEER ratings on their packaging and ads. They claim their units have the highest AC efficiency, but what exactly does “SEER” mean to you and your Davenport, FL home?
What SEER Means
SEER stands for Seasonal Energy Efficiency Ratio and is a value that represents the ratio of the cooling output of an AC unit over a season divided by the energy it consumed. Simply put, the SEER rating is a number that shows just how efficient your air conditioner is over a period of time.
SEER Ratings are Important
Air conditioners with a higher SEER rating are more energy efficient than those with lower atings. However, a unit’s SEER rating shows how efficiently the system can run at its peak, not how efficiently it runs all the time. The SEER rating advertised on a unit’s packaging will be its highest rating during the season, not what it will be throughout the entire year. In other words, think of SEER the way you think of your car’s fuel efficiency. It may get 40 miles per gallon sometimes, but it only gets a fraction of that if you’re in dense traffic.
Typical SEER Ratings
Air conditioners made during the 1970s and 1980s used to have SEER ratings of about eight or nine. Today, the efficiency of AC units has greatly increased. Some states require HVAC companies to sell AC units with a minimum SEER rating of 14, while others have no restrictions. A SEER rating in the low-20s is generally considered a good number. However, remember: the SEER rating only shows the maximum AC efficiency, so while your AC unit might be producing a SEER of 22 at night when it’s 70 degrees, the SEER will probably be lower during hot summer days.
