5 Ton Goodman 15.4 SEER2 R-32 Two-Stage Gas Package Unit GPGM56014031
The Goodman GPGM56014031 is the flagship of the GPGM5 series. It is a 5 ton, two-stage R-32 gas package unit with the line's highest efficiency rating (15.4 SEER2), largest cooling capacity (58,000 BTUh), and biggest furnace. Its six-burner, two-stage gas section is rated at 135,000 / 101,250 BTU input, delivering up to 109,350 BTU of heat at 81% AFUE. A 1 HP variable-speed ECM blower moves 1,875 CFM across a 4-row aluminum-copper evaporator coil, built into Goodman's extra-large cabinet. Explore more 5 ton gas package units.
Is a 5 Ton Two-Stage Gas Package Unit 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 GPGM56014031 is a major step from the 4 ton: 12,000 BTUh more cooling, 600 CFM more airflow, and roughly 28,000 more BTU of high-stage heat output.
The 5 ton uses its own extra-large cabinet, roof curb, and duct layout, so plan the installation carefully. No square to round adapter is available for the 5 ton GPGM5. Round duct connections must be fabricated on site by your contractor, or made with Goodman's 18-inch concentric duct adapter kit. Confirm the duct system can carry 1,875 CFM before installing.
Ideal for: Very large homes in mixed and cold climates, restaurants, retail stores, offices, churches, and workshops with 5 ton cooling loads and heavy heating demand on single-phase power.

Frequently Asked Questions
Is a square to round adapter available for the 5 ton GPGM5?
No. The 5 ton GPGM56014031 does not have a square to round adapter available. If one is needed, it must be made on site by your contractor. Goodman offers the 0270L01338 18-inch concentric duct adapter kit for this size.
What is the heating input of the GPGM56014031?
Goodman's product specifications list a two-stage input of 135,000 BTU (high) and 101,250 BTU (low), with 109,350 and 82,000 BTU output at 81% AFUE. The model number uses a "140" heat input designation.
Does the 5 ton GPGM5 use the same cabinet as the 2–4 ton models?
No. The 5 ton uses an extra-large chassis of about 73-3/8 x 47-5/8 inches, with its own duct openings (17 x 12 supply, 11 x 25 return), its own 0221L00014 roof curb, and 0270L01250 hurricane restraint clips.
What type of evaporator coil does the 5 ton GPGM5 use?
The 5 ton uses a 4-row, 9.2 sq ft aluminum-copper evaporator coil. The 2–4 ton models use all-aluminum coils.
What electrical service does the GPGM56014031 need?
The unit requires a minimum circuit ampacity of 43.3 amps and a maximum 70 amp time-delay fuse or HACR breaker on 208/230V single-phase power.
Which propane and high-altitude kits fit the 5 ton GPGM5?
Goodman lists the LPHE-036072 LP conversion kit, the HAKT036150 high-altitude kit, and the HEFLUE048060 flue extension kit for the GPGM560 models.
