2.5 Ton Goodman 15.2 SEER2 R32 A/C System GLXS5BA3010, AMST30BU1300
This GLXS5B package delivers 30,000 BTU/h from the high-efficiency GLXS5BA3010 condenser. It's matched with the slim AMST30BU1300 air handler and rated 15.2 SEER2 (AHRI #215380415). Many 15.2 SEER2 matches need a wider C-cabinet air handler, but this one keeps the 17.5" B cabinet. That makes it a practical upgrade for homeowners and installers replacing a 2.5 ton system in a narrow hall closet or tight attic. It uses a scroll compressor and R-32 refrigerant, and it's cooling only with optional field-installed Goodman heat strips.
Is a 2.5 Ton Air Conditioning System the Right Size?
With 30,000 BTU/h of nominal cooling, 2.5 tons commonly serves average single-family homes and townhouses, often around 1,200–1,500 sq. ft. as a loose guide. The GLXS5 upgrade raises efficiency, not capacity, so a load calculation should still set the tonnage.
Homes that feel sticky with an older 2.5 ton unit may have an oversized system, poor airflow or leaky ducts rather than a capacity shortage. It's worth checking all three before replacing. Big windows, second-floor bedrooms and dark roofing push the load up, while shade trees, radiant barriers and new windows bring it down.
Ideal for: 3-bedroom homes, townhouses and ranch homes with a narrow closet or attic space that still want premium 15.2 SEER2 efficiency.
Need more capacity? Step up to the 3 Ton Goodman 15.2 SEER2 R32 A/C System GLXS5BA3610, AMST36CU1300 for larger or sunnier homes.
Recommended home sizes are general guidelines only. Actual system requirements depend on insulation, climate, windows, ductwork, occupancy and a proper load calculation. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
Why is the 2.5 ton GLXS5 condenser so much larger than the GLXS4 version?
Goodman builds the GLXS5BA3010 on a 35-1/2" x 35-1/2" x 39-1/2" chassis at 192 lbs, compared with 29" x 29" x 32" for the GLXS4BA3010. The larger unit is part of Goodman's high-efficiency GLXS5B design.
How does this compare with the 2.5 ton GLXS4 15.2 SEER2 system?
Both are rated 15.2 SEER2. This system uses a scroll compressor and the slim 17.5" AMST30BU1300. The GLXS4 version uses a rotary compressor and the wider 21" AMST36CU1300.
Will the 17.5" AMST30BU1300 fit a narrow closet?
Its actual cabinet width is 16-5/16" and its depth is 17-9/16". Make sure the space also allows for its 53-7/16" height, the return plenum and service access.
Is a crankcase heater available for the GLXS5BA3010?
Yes. Goodman lists the 0163R00006 crankcase heater and the 0130M00106 CCH temperature switch as field-installed accessories for this model.
Is there a 2.5 ton heat pump version in the GLXS5 family?
Yes. The 2.5 ton Goodman GLZS5 R32 heat pump system with the AMST30BU1300 provides both heating and cooling.
What does the "A" region code in GLXS5BA3010 mean?
In Goodman's nomenclature, the seventh character "A" stands for All Regions, and the "B" before it indicates the standard feature package.
"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).
