5.0 Rating

The next time you’re looking for a new air conditioner for your St. Louis area home, you’re sure to come across a SEER rating. In fact, it’s one of the most important factors you should take into account when you’re choosing a unit. So what is a SEER rating and what does it mean for your current and future air conditioners?

What is a SEER rating?

SEER stands for “seasonal energy efficiency ratio.” It is a measurement that was defined by the Air Conditioning, Heating and Refrigeration Institute that calculates the amount of energy that is needed to produce a specific cooling output over a typical season.

In other words, SEER is a number given to air conditioning units that describes how energy efficient they are. The higher the number, the more efficient the unit is.

How is a SEER rating calculated?

A SEER rating is calculated by taking the cooling output of an air conditioner (measured in Btu) during a typical cooling season and dividing it by the total energy input (measured in watt-hours) over the same time period. This is similar to an AFUE rating of a furnace in that it measures the difference between how much energy is used to power a unit and how much energy that unit actually gives in return.

What are the SEER standards?

As of January 20, 2006, any newly manufactured air conditioning unit must have a SEER rating of 13 or more. That’s 30 percent more efficient than the previous standard, which was a SEER of 10.

It’s important to know that many older air conditioners have SEER ratings of as low as 6 or lower. Given the lack of efficiency of these units, it’s often more cost-effective in the long run for homeowners to install a new unit with a higher SEER rating than it is to continue to run a unit with a low SEER rating.

If you have any questions about a SEER rating, or if you’d like your air conditioner serviced by a high quality contractor, contact Jerry Kelly, your St. Louis area heating and cooling company.

Jerry A. Was very nice and explained everything to me and my wife. He let us know what things would cost. He wore his mask and work shoe covers when inside. He made a uneasy situation enjoyable.
