San Antonio AC Efficiency Ratings Explained

AC Efficiency Ratings Explained

Is it time to get rid of that old, inefficient air conditioner? So many things have changed since you last bought an AC unit in San Antonio or maybe you’re a first time buyer – either way, understanding the energy efficiency ratings is a must in the buying process. You’ll need to learn exactly how important these ratings are, what they stand for, and how they play a role in your overall comfort.

Generally speaking, your system’s performance will be measured by SEER or Seasonal Energy Efficiency Ratio. The higher the SEER is, the more efficient your system will operate. The more efficient your system operates, the more you save on your utility bills. The “drawback” to a high SEER system is that it’s generally more expensive up front, but may pay for itself quickly with energy savings.

SEER measures the energy efficiency of air conditioning and heat pump systems. It is the ratio of amount of cooling to the amount of energy it consumes by watts per hour over a hypothetical season. You can use the SEER rating to give you an idea of the efficiency of a unit under moderate conditions while keeping in mind that regular maintenance and cleaning can tremendously affect the efficiency.

EER, like SEER, measures the efficiency of an air conditioner but over a typical temperature instead of a season.

AFUE or the Annual Fuel Utilization Efficiency rating measures average efficiency for furnaces, boilers, and water heaters over a hypothetical heating season.

AHRI is the governing body for ratings and that homeowners should request an AHRI certificate for a system they are considering so they can see how it is rated.

Understanding these terms just opens the doors for a better understanding of the HVAC industry and its buying process. If you’re looking for a San Antonio AC replacement, contact Dilmak today at 210-649-3333 for expert advice and service!
