What Does SEER Mean?

July 2019 – SEER or Seasonal Energy Efficiency Ratio is an important rating in the HVAC industry. Knowing what it is and what it means can mean a big difference in what kind of air conditioning system is best for you.

SEER is the cooling generated during a typical summer divided by the total of electricity used during that time.  The higher the SEER rating, the more energy efficient the air conditioner will be. In other words, the higher the rating the more money you will save. Note, however, that while all air conditioners have a SEER rating, it is a maximum value and most likely will never be reached unless conditions are ideal.

In Canada all air conditioners must have at least a 13.0 SEER rating or better. Most air conditioners on the market will meet that and more. But like anything else, it is only one factor in maintaining a certain level of comfort in your home and place of business at a reasonable price. Proper maintenance and certain practices like replacing your furnace air filter on a regular basis can also make a big difference to your bottom line.
