3 Ton Goodman 15.2 SEER2 R32 Heat Pump Wall Mount System GLZS4BA3610, AWST36LU13 Apartment/Condo Type
The largest system in Goodman's R-32 wall-mount line, the 3 ton heat pump pairs the GLZS4BA3610 outdoor unit with the AWST36LU13 large-chassis air handler. It's a 15.2 SEER2, AHRI-certified match (AHRI #215217494). It's also the only size in this group with a scroll compressor and a wider 35-1/2" outdoor cabinet, and the air handler delivers the most airflow of any AWST model. It's built for big condos, penthouses, and multi-family units that need full 3 ton capacity in a wall-hung closet.
Is a 3 Ton Heat Pump System the Right Size?
Three tons is the top of the AWST wall-mount range. It's meant for larger condos and apartments with three or more bedrooms, open living areas, or significant glass and sun exposure.
Before choosing it, confirm the load with a calculation. Also check that the supply and return ductwork can carry about 1,100–1,230 CFM and that the closet fits the 24" W x 21" D large chassis. An oversized system in a small unit can short-cycle and struggle with humidity.
Ideal for: Three-bedroom condos, penthouses, large corner apartments, and multi-family units with high heating and cooling loads.

Frequently Asked Questions
What makes the 3 ton GLZS4BA3610 different from the smaller wall-mount systems?
It's the only size in this group with a scroll compressor (the 1.5–2.5 ton models use rotary compressors). It also has a wider 35-1/2" outdoor cabinet and a 7/8" suction line.
Is 3 tons the largest AWST wall-mount air handler Goodman makes?
Yes. The AWST series runs from 1.5 to 3 tons, so the AWST36LU13 is the top of the range.
What line set size does the 3 ton outdoor unit need?
Goodman specifies a 3/8" liquid line and 7/8" suction line for the GLZS4BA3610, while the AWST36LU13 coil connects at 3/8" and 3/4". Any suction adapter must be supplied in the field. Follow both installation instructions.
How much space does the GLZS4BA3610 outdoor unit need?
The unit measures 35-1/2" W x 35-1/2" D x 35-3/4" H, larger than the 29" cabinets on the smaller sizes. Allow the clearances listed in the installation manual.
Will this heat pump work in climates that drop below 0°F?
Goodman requires the OT18-60A outdoor thermostat with lockout where temperatures fall below 0°F with 50% or higher relative humidity. The factory heat strip provides backup heat.
Can the GLZS4BA3610 be anchored for hurricane-prone areas?
Yes. When properly anchored, Goodman states it meets 2023 Florida Building Code unit-integrity requirements for hurricane-type winds. The ABK-20 anchor bracket kit is available.
"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).
