SEER2 Conversion Formula:
| From: | To: |
The SEER to SEER2 conversion allows you to convert traditional SEER (Seasonal Energy Efficiency Ratio) ratings to the newer SEER2 standard. SEER2 uses updated testing procedures that better reflect real-world conditions.
The calculator uses the SEER2 conversion formula:
Where:
Explanation: The 0.95 conversion factor approximates the difference between the older M1 testing procedure and the new M1 blower testing method used for SEER2 ratings.
Details: SEER2 ratings provide a more accurate representation of real-world energy efficiency performance. The updated testing standards account for higher external static pressure conditions that better simulate actual installation scenarios.
Tips: Enter the SEER rating in BTU/Wh. The calculator will automatically convert it to the equivalent SEER2 rating using the standard conversion factor.
Q1: Why was SEER2 introduced?
A: SEER2 was introduced to provide more accurate energy efficiency ratings that reflect real-world operating conditions with updated testing procedures.
Q2: Is the conversion factor always 0.95?
A: While 0.95 is the standard approximate conversion factor, actual conversion may vary slightly by equipment type and manufacturer specifications.
Q3: When did SEER2 become mandatory?
A: SEER2 ratings became mandatory for new HVAC equipment installations starting in 2023 in the United States.
Q4: Are higher SEER2 ratings better?
A: Yes, higher SEER2 ratings indicate better energy efficiency, which translates to lower operating costs and reduced environmental impact.
Q5: Can I use this calculator for all HVAC equipment?
A: This calculator provides a general conversion for standard air conditioning systems. Specialized equipment may have different conversion factors.
