SEER (Seasonal Energy Efficiency Ratio) rating is defined by the Air Conditioning, Heating, and Refrigeration Institute. The SEER rating is the key efficiency rating for air conditioners and air-source heat pumps. SEER rating of a unit it's a measurement of an air conditioner's cooling capacity to power input. SEER rating reflects overall system efficiency on a seasonal basis.


Substantial energy savings can be obtained from more efficient systems. The higher the unit's SEER rating the more energy efficient it is. For example, by upgrading your Air Conditioner from SEER 9 to SEER 13, the power consumption is reduced by 30%.


In the U.S., the SEER is the ratio of cooling in British thermal unit (BTU) to the energy consumed in watt-hours. The Southwestern Region of the United States of America including Nevada must be at least 14 SEER. Most modern Air Conditioners have a SEER that ranges from 13 to 22.


How manu SEER needed for a typical House in Las Vegas?

In Las Vegas, Nevada - 14 SEER is the minimum because the air conditioning season here is much longer, often from early spring into fall.
