2.5 Ton Goodman 15.2 SEER2 R-32 Single Stage Heat Pump Split System GLZS4BA3010 AMST42CU1300

This Goodman R-32 heat pump system is designed for efficient year-round heating and cooling. The outdoor unit is a 2.5-ton single-stage heat pump, paired with a larger-capacity 3.5-ton multi-position air handler to support higher airflow and system efficiency. The combination is AHRI-certified (Reference #215218038) and delivers up to 15.2 SEER2 cooling efficiency and 7.8 HSPF2 heating efficiency. Together, these Goodman units form a reliable, cost-effective all-electric heat pump system suitable for residential applications. Both are AHRI Certified, ETL Listed, and come with a 10-year limited parts warranty (with online registration).

• Energy Efficiency: Up to 15.2 SEER2 and 7.8 HSPF2 help lower operating costs compared to lower-efficiency systems.
• Year-Round Comfort: Provides both reliable cooling and efficient heating in a single system.
• Quiet Operation: SmartShift® defrost and ECM blower reduce noise levels (outdoor unit rated at 77 dBA).
• Installation Flexibility: Multi-position air handler and pre-charged outdoor unit simplify setup; 21″ cabinet depth aids attic installations.
• Durability & Reliability: Robust construction, protective features, and long warranty coverage.
• Future-Ready Refrigerant: Uses lower-GWP R-32 refrigerant (A2L compatible).
• Airflow Performance: Oversized indoor unit supports higher CFM for better comfort and system matching.
