1. What is SEER and EER?

SEER (Seasonal Energy Efficiency Ratio) and EER (Energy Efficiency Ratio) are measures of air conditioning and heat pump cooling efficiency. EER measures immediate efficiency while SEER measures seasonal efficiency.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• SEER — Seasonal Energy Efficiency Ratio (BTU/Wh)
• EER — Energy Efficiency Ratio (BTU/h per W)
• 0.875 — Conversion factor for fixed speed units

Explanation: This formula provides an estimate of SEER from EER for fixed speed air conditioning units.

3. Importance of SEER Calculation

Details: SEER is important for understanding the seasonal energy efficiency of cooling equipment, which affects energy costs and environmental impact.

4. Using the Calculator

Tips: Enter the EER value in BTU/h per W. The calculator will estimate the corresponding SEER value.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between SEER and EER?
A: EER measures efficiency at a specific temperature (95°F), while SEER measures seasonal efficiency across varying temperatures.

Q2: Is this conversion accurate for all units?
A: This is specifically for fixed-speed units. Variable-speed units may have different conversion factors.

Q3: What is a good SEER rating?
A: Modern units typically range from 14-25 SEER. Higher numbers indicate better efficiency.

Q4: Why is SEER important?
A: Higher SEER units consume less energy for the same cooling output, reducing electricity costs.

Q5: Can I use this for heat pumps?
A: This conversion applies to cooling efficiency. Heat pumps have separate HSPF ratings for heating efficiency.
