What SEER2 Ratings Actually Mean

SEER2 stands for Seasonal Energy Efficiency Ratio 2, and it measures how efficiently an air conditioning system converts electricity into cooling. The higher the SEER2 rating, the less energy the system uses to cool your home.

In Phoenix, SEER2 ratings matter more than almost anywhere else in the country. That’s because air conditioners here run longer and harder due to extended periods of extreme heat. Even small efficiency differences can add up to significant energy savings over time.

SEER2 replaced the older SEER rating system and reflects more realistic operating conditions, including higher external static pressure. This gives homeowners a better understanding of how systems perform in real-world installations.

Higher-SEER2 systems typically offer better comfort as well. Variable-speed technology allows the system to adjust output based on demand, maintaining more consistent temperatures and reducing wear on components.

When comparing HVAC systems, focusing only on upfront price can be misleading. Over a 15-year lifespan in Phoenix, energy savings from higher efficiency often outweigh the initial cost difference.
