Explaining HVAC SEER ratings
SBS-NC, LLC Commercial HVAC • February 6, 2023

Explaining Air Conditioning SEER ratings with examples!

     SEER (Seasonal Energy Efficiency Ratio) is a measurement used to determine the efficiency of air conditioning units. It is calculated by dividing the total cooling output of a unit over a season by the total energy used during that same time period. According to the US Department of Energy, the higher the SEER rating, the more efficient the unit is, and the lower the energy costs for the homeowner.


     SBS-NC, LLC HVAC is committed to providing the highest-quality air conditioning units to our customers. That's why we only offer units with high SEER ratings, ensuring that our customers are getting the most efficient units on the market. With our units, customers can expect to save money on their energy bills, as well as reduce their carbon footprint by using less energy, as stated by the Environmental Protection Agency (EPA).


     When considering an air conditioning unit, it's important to keep in mind that not all units are created equal. For example, a unit with a SEER rating of 13 is much less efficient than a unit with a SEER rating of 21, according to Energy Star, a program of the EPA. This is why it's so important to choose a unit with a high SEER rating, and why SBS-NC, LLC HVAC only offers units with high ratings.


     To give you an idea of the difference a high SEER rating can make, let's take a look at three examples:


  • A unit with a SEER rating of 13 will use approximately 15% more energy than a unit with a SEER rating of 21, according to Energy Star. This means that a homeowner could save hundreds of dollars each year on their energy bills by choosing a unit with a high SEER rating.


  • A unit with a SEER rating of 21 will last longer than a unit with a SEER rating of 13, as it will not have to work as hard to maintain a comfortable temperature, according to Energy Star. This means that homeowners will not only save money on their energy bills, but they will also save money on repairs and replacements.


  • A unit with a high SEER rating will also produce less carbon emissions, making it a more environmentally friendly option, according to the EPA. By choosing a unit with a high SEER rating from SBS-NC, LLC HVAC, homeowners can enjoy a comfortable home while also reducing their carbon footprint.


     In conclusion, SEER ratings are a critical factor to consider when choosing an air conditioning unit. By choosing a unit with a high SEER rating from SBS-NC, LLC HVAC, homeowners can save money on their energy bills, reduce their carbon footprint, and enjoy a comfortable home for years to come, as confirmed by the US Department of Energy, Energy Star, and the EPA.
