The SEER rating system comprises three regions based on the state's climatic conditions and locations. SEER stands for Seasonal Energy Efficiency Ratio and is a measure of the cooling output of an air conditioning system relative to the amount of energy it consumes. The higher the SEER rating, the more efficient the system is.
In the Southwest Region, specifically Prescott, AZ, where summers can be scorching and humid, having an air conditioning system with a high SEER rating is crucial. Not only will it keep you cool and comfortable, but it will also save you money on your energy bills in the long run.
History and Details of SEER Ratings
The U.S. Department of Energy and the Air Conditioning, Heating, & Refrigeration Institute created the SEER measurement ratings system in the 1990s to measure the efficiency of air conditioning systems. The rating is calculated by dividing the system's cooling output by the total energy consumed during a typical cooling season.
In 2011, the Department of Energy (DOE) started revising its energy conservation rules for heating, ventilation, and air conditioning (HVAC) systems. Previously, a "one-size-fits-all" approach was used. This no longer worked as it did not account for climate differences across the U.S. Therefore, the DOE implemented a new regional approach considering varying climate conditions. By April 2014, the DOE officially confirmed that starting January 1, 2015, efficiency standards for HVAC equipment would vary based on the region of the U.S. in which it was located. The country was divided into three regions - the North, the South, and the Southwest.
Each region has different climate conditions and, therefore, different SEER rating requirements for air conditioning systems. This regional approach ensures that air conditioning systems operate efficiently in various climates.
How It Applies in Prescott, Az Southwest Region
Hot and humid conditions can impact the SEER rating of an air conditioning system. In such situations, the air conditioner has to work harder to remove moisture from the air and cool it. This can result in lower efficiency and higher energy consumption, which can lower the SEER rating of the system.
Given Prescott's climate conditions, the appropriate SEER rating for an air conditioning system in Prescott, AZ, is now 15. A system with a SEER rating of 15 would provide relatively efficient cooling performance for the region, while a system with a higher SEER rating would be more energy-efficient and provide even greater cooling performance.
It's worth noting that the appropriate SEER rating for an air conditioning system in Prescott, AZ, may also depend on other factors, such as the size of the home or building being cooled, the orientation of the building, and the level of insulation. A qualified HVAC contractor can help determine the appropriate SEER rating for a particular application based on a thorough assessment of these and other relevant factors.
New SEER Standards for 2023
As of January 1, 2023, the federal minimum increased the SEER rating by 1 for all regions, A.C. units, and heat pumps. This change includes central air conditioners and split systems like ductless mini splits.
Region | A.C. Minimum SEER (2022) | A.C. Minimum SEER 2023 | Heat Pump Min. SEER (2022) | Heat Pump Min. SEER 2023 |
North | 13 | 14 | 14 | 15 |
Southeast | 14 | 15 | 14 | 15 |
Southwest | 14 | 15 | 14 | 15 |
Products affected by SEER2 Regulations:
Air Conditioner Condensing Units
Heat Pumps
Single Packaged Units
Evaporator Coils
Gas Furnaces
The United States Environmental Protection Agency mandates that
central air conditioners and heat pumps have a SEER efficiency rating of at least 14. However, numerous ENERGY STAR-qualified models exceed this rating, providing even more significant energy savings. By reducing the power required to cool your home, this rating can significantly decrease your monthly energy costs.
As SEER standards continue to increase and technology advances, choosing an air conditioning system that meets the highest efficiency and quality standards is more important than ever. By doing so, you can ensure that you stay cool and comfortable all summer while saving money and reducing your carbon footprint.
