Our newest inverter condenser line has completed AHRI certification testing with a peak SEER2 rating of up to 20 — the highest efficiency rating in DEPLUS product history, and among the top performers in the residential HVAC market.
What SEER2 Means for Contractors
SEER2 (Seasonal Energy Efficiency Ratio 2) is the updated efficiency standard implemented in 2023. Unlike the legacy SEER rating, SEER2 uses a higher external static pressure in testing — 0.5 in.w.g. vs. the original 0.1 — making it a more accurate representation of real-world installation performance.
For contractors, a system rated up to 20 SEER2 opens doors to utility rebate programs, ENERGY STAR qualification, and increasingly, building code compliance in states with progressive energy standards.
