There are many ways to measure the effectiveness of an Air Conditioning unit. The SEER rating is one of the more complex ratings, but it can help you decide between one brand of AC unit over another.
When we are talking about ETUs or BTUs, we are really talking about the mechanical functionality of an air conditioner unit. This means that two air conditioner units of similar make and size could have the same BTUs and there would be functionally no difference between them. However, let’s say two AC units are 1500 BTUs, but these two units could have very different SEER Ratings.
Considering The SEER Rating
Considering the SEER Rating is easy. SEER stands for Seasonal Energy Efficiency Rating. It is generally a number between 13 and 25, with the higher numbers indicating a better energy efficiency. The number is the energy efficiency during an average summer (89 degrees) and is measured on wattage needed to cool. In America, no unit with a base SEER Rating lower than 14 is allowed to be sold. We say base SEER Rating because for every 5 degrees over 89, 1 point is removed from the SEER rating. This means that your unit with a 14 SEER may only operate at a 12 when the temperature outside is 99 degrees.
How To Use The SEER Rating
The bottom line is that the SEER rating gives you a way to compare similar or identical units against one another. Once one of our trained technicians measures and determines the size of the unit you need, you will be able to go out and shop for units based on their energy efficiency or SEER rating.
