1.5 Ton Goodman 15.2 SEER2 R32 A/C System GLXS4BA1810, AMST30BU1300
This is the high-efficiency 1.5 ton match in the Goodman GLXS4B R-32 lineup. It pairs the 18,000 BTU/h GLXS4BA1810 condenser with the larger 30,000 BTU/h-rated AMST30BU1300 air handler, reaching 15.2 SEER2 under AHRI certificate #215214927. It suits condo owners, small-home owners and landlords who want the most rated efficiency from a 1.5 ton R-32 system and have closet or attic room for a taller air handler. It's cooling only as shipped, with optional field-installed Goodman electric heat strips.
Is a 1.5 Ton Air Conditioning System the Right Size?
With 18,000 BTU/h of nominal cooling, this system fits homes and units with a light cooling load. As a loose reference, that's often compact condos, apartments and small homes around 600–900 sq. ft. The larger air handler raises the efficiency rating, not the capacity. So sizing should still follow the home's calculated heat gain, just as it would with a standard 1.5 ton match.
Upper-floor condos under a hot roof, units with big sliding glass doors, and older homes with leaky ducts can all carry more load than their square footage suggests. Shaded ground-floor units and newer, well-sealed construction may need less. A Manual J load calculation confirms that 1.5 tons is correct before you invest in the higher-efficiency match.
Ideal for: Efficiency-minded condo and apartment owners, small single-story homes, in-law suites and rental units where lower operating cost matters.
Need more capacity? Step up to the 2 Ton Goodman 15.2 SEER2 R32 A/C System GLXS5BA2410, AMST24BU1300 to keep the same efficiency rating with more cooling capacity.
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.

Outdoors, the GLXS4BA1810 condenser keeps its compact 26" x 26" x 27" cabinet and 117 lb weight. Indoors, the AMST30BU1300 air handler keeps the slim 17.5" B cabinet width but stands 53-7/16" tall. That's about 8-1/2" taller than the AMST24BU1300 used in the standard 1.5 ton match. Measure closet height or attic clearance before choosing this package. If space is tight, the 1.5 ton GLXS4BA1810 with AMST24BU1300 offers a shorter cabinet.

Frequently Asked Questions
Why is a larger air handler paired with a 1.5 ton condenser?
The AMST30BU1300 has a coil rated for up to 30,000 BTU/h. Pairing it with the 18,000 BTU/h GLXS4BA1810 gives the refrigerant more coil surface to work with. That raises the AHRI-rated efficiency of this match to 15.2 SEER2 while keeping 1.5 ton capacity.
How does this system compare to the GLXS4BA1810 with AMST24BU1300?
Both use the same 1.5 ton condenser. This package steps up to the AMST30BU1300 for a 15.2 SEER2 rating. The trade-off is height: the AMST30BU1300 is 53-7/16" tall versus 45" for the AMST24BU1300.
Will the taller AMST30BU1300 fit where my old air handler was?
It keeps the 17.5" B cabinet width (16-5/16" actual) and 17-9/16" depth. Check that your closet, platform or attic has room for its 53-7/16" height plus plenum and service clearance.
What does a 15.2 SEER2 rating mean for operating cost?
SEER2 measures seasonal cooling efficiency. A higher rating means the system uses less electricity to deliver the same cooling. Actual savings depend on your climate, utility rates, thermostat habits and installation quality.
Can I keep my existing ductwork with this 1.5 ton system?
Often, yes, if the ducts are sealed and sized for 1.5 ton airflow. Your installer should check static pressure and choose the right ECM speed tap using the airflow tables in the AMST R32 Technical Specifications.
Is this system a good choice for humid climates?
Right-sizing matters most in humid climates. A properly sized 1.5 ton system with an internal TXV and a selectable ECM airflow tap helps with moisture removal, and Goodman offers the HHK0004 high humidity kit for the AMST30BU1300.
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).
