5 Ton Goodman 13.4 SEER2 R-32 Two-Stage Package Air Conditioner GPCH36031
The Goodman GPCH36031 is the largest unit in the GPCH3 series and the only one with a two-stage scroll compressor. It is a 5 ton package air conditioner that delivers 56,000 BTUh of total cooling and 1,675 CFM of airflow from a 5-speed ECM blower, with TXV refrigerant metering and a large 7.01 sq ft, 4-row evaporator coil. Two-stage operation lets the unit run at a lower stage when full capacity isn't needed, for steadier comfort in very large homes and commercial spaces. It is factory charged with R-32, rated at 13.4 SEER2, and approved for heat kits up to 20 kW. Shop more Goodman equipment.
Is a 5 Ton Package Air Conditioner the Right Size?
Five tons is the top of the single-phase residential range. It suits cooling loads of about 55,000 to 60,000 BTUh, such as very large homes, open commercial floors, restaurants, and high-occupancy spaces. The GPCH36031 adds 11,000 BTUh of total cooling over the 4 ton and moves to Goodman's large chassis, with a bigger 18.85 sq ft, 2-row condenser coil.
Because a 5 ton system moves a lot of air, confirm that the duct system can deliver about 1,675 CFM before installing. If the load exceeds 5 tons, two smaller units or a three-phase commercial rooftop unit is usually better than oversizing. Heat kits from 5 kW to 20 kW are approved for this size.
Ideal for: Very large single-family homes, restaurants, retail stores, offices, churches, and workshops with 5 ton cooling loads on single-phase power.

Recommended applications are general guidelines only. Actual system requirements depend on insulation, ductwork, climate, window area, occupancy, and a proper load calculation. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
What does a two-stage compressor do on the GPCH36031?
A two-stage compressor can run at a lower capacity stage when cooling demand is moderate, and switch to full capacity on the hottest days. The 5 ton is the only GPCH3 with a two-stage compressor. The other sizes use single-stage compressors.
How does the 5 ton GPCH36031 differ from the 4 ton GPCH3?
It adds 11,000 BTUh of total cooling (56,000 vs. 45,000), increases airflow to 1,675 CFM, and switches from piston to TXV metering. It also uses a two-stage compressor and the larger chassis. Electrical increases to 40.6 MCA with a 60 amp breaker.
Is a square to round adapter available for the 5 ton GPCH3?
Yes. Goodman lists the SQRPCH102-103 for horizontal applications and the SQRPC102-103 for downflow on a PCCP roof curb. Both cover the medium and large chassis, including the 5 ton.
What electrical service does the GPCH36031 need with a 20 kW heat kit?
With the HKTPD201 20 kW kit on a single-point connection, Goodman lists 135.64 MCA and a 150 amp maximum overcurrent device. Without a heat kit, the unit needs 40.6 MCA and a 60 amp maximum breaker.
How much refrigerant is in the 5 ton GPCH3?
The GPCH36031 is factory charged with 78 oz. of R-32, the largest charge in the GPCH3 series.
What warranty coverage does the GPCH36031 carry?
Goodman offers a 10-year parts limited warranty when online registration is completed within 60 days of installation. Registration is not required in California, Florida, or Québec, and coverage terms differ in some cases in Texas and Florida. See the warranty certificate for details.
