2.5 Ton Goodman 15.2 SEER2 R32 Heat Pump System GLZS5BA3010, AMST30BU1300
For mid-size family homes, the Goodman 2.5 ton heat pump system pairs the GLZS5BA3010 R-32 outdoor unit with the dedicated AMST30BU1300 ECM air handler (AHRI #218222709). It is rated at 15.2 SEER2 and produces about 28,600 BTU/h of cooling at 95°F and 28,600 BTU/h of heating at 47°F, with 1,060 CFM of rated airflow. This size moves to Goodman's larger 35-1/2" outdoor cabinet for more coil surface. It suits homeowners and contractors replacing aging 2.5 ton equipment with a modern R-32 system.
Is a 2.5 Ton Heat Pump System the Right Size?
A 2.5 ton system covers a broad range of three-bedroom and ranch-style homes. Its heating output stays close to its cooling output, which helps in climates with real winters as well as hot summers.
Window area, sun exposure, insulation levels, duct leakage, and local design temperatures can push a home's load up or down by half a ton or more. A proper load calculation keeps you from overbuying capacity that short-cycles and leaves the home clammy.
Ideal for: Three-bedroom homes, ranch-style houses, larger townhomes, and homes replacing an existing 2.5 ton heat pump.
Need more capacity? Step up to the 3 Ton Goodman 14.8 SEER2 R32 Heat Pump System GLZS5BA3610, AMST36BU1300 for homes with a higher calculated load.
Recommended sizing is a general guideline only. Actual system requirements depend on insulation, climate, ductwork, windows, occupancy, and home layout. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

The outdoor unit includes high- and low-pressure switches, a factory-installed suction-line accumulator, and a compressor crankcase heater.
GLZS5B Technical Specifications
Goodman Warranty Certificate"SEER2" stands for Seasonal Energy Efficiency Ratio 2. Specifically, SEER2 is the total heat removed from the conditioned space during the annual cooling season. The M1 testing procedure will increase systems' external static pressure by a factor of five to better reflect field conditions of install equipment. With this change, new nomenclature will be used to denote M1 ratings (including EER2 and HSPF2).
