2.5 Ton Goodman 15.2 SEER2 R32 A/C System GLXS4BA3010, AMST36CU1300
This package takes the 30,000 BTU/h GLXS4BA3010 R-32 condenser up to 15.2 SEER2 by matching it with the AMST36CU1300, a 36,000 BTU/h-rated C-cabinet air handler. The pairing is listed under AHRI certificate #215214933. It's a good fit for homeowners in average-sized homes who want better rated efficiency than the standard 2.5 ton match. It also suits installers working with a wider closet, attic platform or existing 21" return plenum. It's cooling only, with support for optional field-installed electric heat.
Is a 2.5 Ton Air Conditioning System the Right Size?
This system still delivers 2.5 tons (30,000 BTU/h) of nominal cooling. The larger indoor coil improves the efficiency rating, not the capacity. As a general benchmark, 2.5 tons often serves homes around 1,200–1,500 sq. ft. The real answer comes from a load calculation that accounts for how your home is built and where it sits.
Think about attic insulation depth, the direction your largest windows face, whether a second-story bedroom wing gets afternoon sun, and how well the ducts are sealed. Choosing the high-efficiency match makes the most sense once you've confirmed 2.5 tons is the right capacity. Then the SEER2 upgrade pays off over every cooling season.
Ideal for: 3-bedroom homes, townhouses and split-level homes where the owner wants a higher-efficiency 2.5 ton R-32 system.
Need more capacity? Step up to the 3 Ton Goodman 15.2 SEER2 R32 A/C System GLXS4BA3610, AMST42CU1300 for larger homes at the same efficiency rating.
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.
What's Included

| Application | High-Efficiency Cooling-Only Split System (Electric Heat Kit Optional) |
| Refrigerant | R-32 |
| Compressor | Single-Stage Rotary Compressor with Advanced Copeland® Technology |
| Metering Device | Factory-Installed Internal Thermal Expansion Valve (TXV) |
| Electrical | 208/230V, Single Phase, 60 Hz Condensing Unit — 15.0 MCA / 25A Max Overcurrent |
| Air Handler Electrical | 208/240V, Single Phase — 7.1 MCA / 15A Max Overcurrent (No Heat Kit) |
The GLXS4BA3010 condenser measures 29" x 29" x 32" with a 71 dBA sound rating and a 63 oz. factory charge. The AMST36CU1300 air handler is shorter than the AMST30BU1300 used in the standard 14.5 SEER2 2.5 ton system, at 49" versus 53-7/16". It's wider, though, at 19-13/16" in the 21" C cabinet, with an 8"-wide blower wheel. That makes it a smart choice where height is limited but width isn't. For condos with an in-wall closet, the 2.5 ton Goodman R32 central wall mount system is another option.

Frequently Asked Questions
What do I gain choosing this 2.5 ton system over the 14.5 SEER2 version?
A higher efficiency rating. Pairing the GLXS4BA3010 with the AMST36CU1300 is AHRI rated at 15.2 SEER2, compared with 14.5 SEER2 for the AMST30BU1300 match. Cooling capacity stays at 30,000 BTU/h.
Is the AMST36CU1300 too big for a 2.5 ton condenser?
No. It's an AHRI-certified match (#215214933). The installer sets the ECM blower to the airflow tap suited to 2.5 ton operation, and the larger coil is what improves the SEER2 rating.
Why is this air handler shorter but wider than the AMST30BU1300?
The AMST36CU1300 fits its coil in a wider 21" C cabinet, so it only needs 49" of height. The AMST30BU1300 stays in the narrower 17.5" B cabinet and grows to 53-7/16" tall.
Is there a wall-mount option for a 2.5 ton R-32 system?
Yes. For in-wall closet installs common in condos and apartments, see the 2.5 ton Goodman R32 central wall mount system GLXS4BA3010, AWST30LU13.
What does choosing an ECM speed tap do?
The AMST36CU1300's multi-speed ECM motor has nine speed taps (T1–T9). Your installer picks the tap that delivers the right airflow for the condenser and your duct static pressure, using Goodman's airflow tables.
How often should I check the filter in the AMST36CU1300?
Inspect the 19.5" x 20" filter regularly and replace it as recommended by the filter manufacturer, or sooner in dusty homes or homes with pets. Tool-less access makes the swap quick.
GLXS4B Technical Specifications"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).
