1. What is SEER to SEER2 Conversion?

The SEER to SEER2 conversion allows you to convert traditional SEER (Seasonal Energy Efficiency Ratio) ratings to the new SEER2 standard. SEER2 uses updated testing procedures that better reflect real-world conditions.

2. How Does the Calculator Work?

The calculator uses the SEER2 conversion formula:

Where:

• \( SEER \) — Traditional Seasonal Energy Efficiency Ratio (BTU/Wh)
• \( SEER2 \) — Updated SEER2 rating (BTU/Wh)
• \( 0.95 \) — Conversion factor

Explanation: The conversion factor of 0.95 accounts for the more stringent testing conditions used in SEER2 calculations compared to traditional SEER ratings.

3. Importance of SEER2 Rating

Details: SEER2 ratings provide a more accurate representation of real-world energy efficiency performance. The updated testing standards better account for external static pressure conditions that affect system performance.

4. Using the Calculator

Tips: Enter the SEER rating in BTU/Wh. The value must be greater than 0. The calculator will automatically compute the equivalent SEER2 rating.

5. Frequently Asked Questions (FAQ)

Q1: Why was SEER2 introduced?
A: SEER2 was introduced to provide more accurate energy efficiency ratings that better reflect real-world operating conditions and updated testing standards.

Q2: Is the conversion exact?
A: The conversion is approximate. While 0.95 is the standard conversion factor, actual differences may vary slightly depending on specific equipment and conditions.

Q3: When should I use SEER2 ratings?
A: SEER2 ratings are becoming the new standard for HVAC equipment efficiency ratings and are required for new installations in many regions.

Q4: What are typical SEER/SEER2 values?
A: Standard efficiency units typically range from 13-16 SEER (12.35-15.2 SEER2), while high-efficiency units can reach 20+ SEER (19+ SEER2).

Q5: Does this affect energy costs?
A: Yes, higher SEER2 ratings indicate better energy efficiency, which typically translates to lower operating costs for cooling your home.
