SEER Conversion Formula:
| From: | To: |
The SEER (Seasonal Energy Efficiency Ratio) to SEER2 conversion allows you to convert between the new SEER2 rating system and the original SEER rating. SEER2 uses updated testing procedures that typically result in slightly lower values for the same equipment.
The calculator uses the SEER conversion formula:
Where:
Explanation: The conversion factor of 1.05 accounts for the differences in testing procedures between the original SEER and newer SEER2 standards.
Details: Understanding the conversion between SEER and SEER2 is crucial for comparing energy efficiency ratings across different generations of HVAC equipment and making informed purchasing decisions.
Tips: Enter the SEER2 rating in BTU/Wh. The calculator will provide the approximate equivalent SEER rating. All values must be valid (SEER2 > 0).
Q1: Why is there a conversion between SEER and SEER2?
A: SEER2 uses updated testing procedures that better reflect real-world conditions, resulting in slightly lower ratings for the same equipment compared to the original SEER standard.
Q2: Is the 1.05 conversion factor exact?
A: The 1.05 factor is an approximation. Actual conversion may vary slightly depending on the specific equipment and testing conditions.
Q3: When did SEER2 become standard?
A: SEER2 standards were implemented for new HVAC equipment installations starting in 2023 in the United States.
Q4: Can I use this for all types of HVAC equipment?
A: This conversion is primarily designed for central air conditioners and heat pumps. Other equipment types may have different conversion factors.
Q5: Why are SEER2 ratings typically lower?
A: SEER2 testing uses more realistic conditions including external static pressure requirements that better simulate actual installation scenarios.
