2.5 Ton Goodman 14.5 SEER2 R32 A/C System GLXS4BA3010, AMST30BU1300
The midpoint of the GLXS4B lineup pairs the 30,000 BTU/h GLXS4BA3010 condenser with the AMST30BU1300 air handler, a combination listed under AHRI certificate #215214932. This 14.5 SEER2 R-32 split system suits growing families and homeowners in average-sized homes. It also works well for contractors replacing aging 2.5 ton central air where the existing air handler sits in a closet or attic. It's cooling only as shipped, and you can add field-installed Goodman heat strips for backup heat on cooler mornings.
Is a 2.5 Ton Air Conditioning System the Right Size?
A 2.5 ton system provides 30,000 BTU/h of nominal cooling. It's a common choice for homes that have outgrown a 2 ton unit but don't have the load for 3 tons. As a very general reference, that's often around 1,200–1,500 sq. ft. The decision should still rest on calculated heat gain, not floor area alone.
Open kitchens, vaulted living rooms, large sliding doors and a second-floor bedroom wing can all push a home toward the upper end of the 2.5 ton range. Upgraded attic insulation, low-E windows and sealed ducts can pull it back down. Room-by-room load math also shows how airflow should be split across supply registers.
Ideal for: 3-bedroom ranch homes, townhouses, split-level homes and average-sized single-family houses with moderate sun exposure.
Need more capacity? Step up to the 3 Ton Goodman R32 A/C System GLXS4BA3610, AMST36CU1300 for larger homes, two-story layouts or higher cooling loads.
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.

The GLXS4BA3010 moves into a larger 29" x 29" x 32" cabinet with a 1/6 HP fan motor. Goodman gives it a 71 dBA sound rating, which is quieter than the 1.5 and 2 ton models. Indoors, the AMST30BU1300 keeps the slim 17.5" B cabinet but stands 53-7/16" tall to house a larger coil. That makes it a practical swap in a standard utility closet. If you prefer higher rated efficiency, compare it with the 2.5 ton GLXS4BA3010 system matched with the AMST36CU1300. You can browse more indoor options in our air handlers category.

Frequently Asked Questions
Who typically buys a 2.5 ton central AC system?
Owners of 3-bedroom ranch homes, townhouses and average single-family homes often land at 2.5 tons, where 2 tons falls short but 3 tons would be oversized.
How does the GLXS4BA3010 differ from the 2 ton model?
The GLXS4BA3010 adds 6,000 BTU/h of capacity. It uses a larger 29" x 29" x 32" cabinet, a 1/6 HP fan motor and a lower 71 dBA sound rating. It's paired with the taller AMST30BU1300 air handler instead of the AMST24BU1300.
What compressor is inside the GLXS4BA3010?
Goodman uses a single-stage rotary compressor with Advanced Copeland® Technology in the GLXS4BA3010. The 3 through 5 ton models move to scroll compressors.
Can the AMST30BU1300 be installed horizontally in an attic?
Yes. The AMST30BU1300 supports horizontal and vertical configurations. It has a coil mounting track for repositioning and secondary drain connections for attic installs.
What filter does the AMST30BU1300 take?
The B cabinet uses a 16" x 20" filter (Goodman part ALFH16201E), with tool-less access for routine changes.
What electric heat kits fit the AMST30BU1300?
Goodman lists HKTS heat kits from 3 kW through the dual-circuit HKTSD15 for this air handler. Kits are sold separately and field installed.

AMST Technical Specifications
AMST Installation Manual"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).
