Efficiency Metrics: Understanding SEER and Beyond
Calculating and interpreting HVAC efficiency ratings for optimal system performance
Your Progress
Section 3 of 5HVAC efficiency is measured through standardized ratings that help consumers compare system performance. Understanding these metrics is crucial for making informed decisions about equipment purchases and upgrades.
SEER (Seasonal Energy Efficiency Ratio) is the most common metric, but EER, HSPF, and other ratings provide additional insights into system performance under different conditions.
System Specifications
Efficiency Ratings
📊 SEER Standards
Minimum 14 SEER for new systems, 20+ SEER for high efficiency
🎯 Efficiency Impact
Higher SEER ratings can reduce energy costs by 30-50%
🌡️ Real-World Performance
Actual efficiency varies based on installation and maintenance
Efficiency Rating Guide
Poor (SEER < 13)
Older systems, high operating costs, inefficient performance
Good (SEER 13-16)
Standard efficiency, reasonable operating costs
Very Good (SEER 16-20)
High efficiency, significant energy savings
Excellent (SEER 20+)
Premium efficiency, maximum energy savings and comfort
