GPCM32431 is a 2.0-ton Goodman GPCM3 R-32 packaged air conditioner built for ducted cooling. Convertible airflow: horizontal or downflow (packaged AC-only).
A packaged air conditioner combines the compressor, condenser coil, evaporator coil, and blower into a single outdoor cabinet—often installed at ground level or on a rooftop—so you don’t need a separate indoor air handler cabinet inside the building.
At-a-glance (this exact model)
| Nominal size | 2.0 ton (model code 24) |
|---|---|
| Rated cooling capacity | 24,000 BTU/h total |
| Sensible capacity (temperature drop portion) | 18,480 BTU/h |
| Efficiency ratings | 13.4 SEER2 / 10.6 EER2 — SEER2 reflects seasonal cooling efficiency and EER2 reflects efficiency at peak conditions; higher numbers mean more cooling per unit of electricity. |
| Refrigerant | R-32 (charge: 63 oz) |
| Indoor airflow (nominal) | 800 CFM via 5-speed ECM blower |
| Sound level | 74 dB (per spec sheet) |
Sizing & selection guidance
“Ton” is a nominal sizing label (1 ton ≈ 12,000 BTU/h). Proper sizing still requires a load calculation (for example, ACCA Manual J/S or a commercial heat gain analysis). Oversized equipment can short-cycle and under-dehumidify; undersized equipment may struggle on design days.
What the model number tells you
Goodman packaged unit model numbers encode the nominal size and electrical configuration.
- 24 = 2 ton nominal size
- 3 = 13.4 SEER2 efficiency tier in this series
- 1 = 208/230 V, 1 phase, 60 Hz
Core components & performance details
| Compressor | Scroll compressor, single-stage (RLA 10.6, LRA 56.5) |
|---|---|
| Condenser coil | Copper tube / aluminum fin |
| Evaporator coil | All-aluminum |
| Metering device | Piston |
| Condensate drain connection | 3/4" NPT |
| Indoor blower motor | ECM, 1/2 HP, 3.8 FLA, 5 speeds |
| Outdoor fan motor | 1/6 HP, 0.95 FLA, 22" blade |
This unit uses R-32 refrigerant (ASHRAE safety class A2L: lower toxicity with mild flammability). Installation and service should follow current local code requirements for A2L refrigerants and be performed by qualified technicians.
Airflow, ductwork & installation planning
| Duct openings (supply / return) | 16x16 / 16x16 (W×H, inches) |
|---|---|
| Airflow configuration | Convertible airflow: horizontal or downflow (packaged AC-only) |
An electric heat kit is available as a field-installed option if you need supplemental/backup heat. Heat kit selection should match local design loads and available electrical capacity.
Downflow note: Downflow installs have extra requirements. Per the spec sheet: a Horizontal Duct Cover is required for all downflow installations, and either a Downflow Economizer or a Downflow Conversion Kit is mandatory for all downflow installations.
Electrical requirements (verify before installation)
| Power supply | 208/230 V, 1 phase, 60 Hz |
|---|---|
| Minimum Circuit Ampacity (MCA) | 18.0 A |
| Maximum Overcurrent Protection (MOCP) | 25 A (use time-delay fuses or HACR breakers per spec sheet) |
Always verify final electrical data on the unit’s nameplate and size wiring per the National Electrical Code and local codes. Long wire runs may require larger conductor sizes.
Dimensions, clearances & weight
| Cabinet footprint (W×D) | 47" × 51" |
|---|---|
| Cabinet height references (A / B) | 32" / 34.75" (chassis size: Medium) |
| Weight (operating / shipping) | 310 / 320 lb |

Warranty
10-Year Parts Limited Warranty available with online registration completed within 60 days of installation (registration not required in California, Florida, or Québec; other limitations and exceptions may apply).
Before you order (quick checklist)
- Confirm you need an AC-only packaged unit (not a heat pump).
- Confirm nominal size: 2.0 ton and rated capacity 24,000 BTU/h.
- Confirm installation orientation/duct configuration: Convertible airflow: horizontal or downflow (packaged AC-only).
- Confirm your electrical service supports the unit’s MCA and MOCP.
- If adding an economizer or downflow setup, confirm the required curb/duct cover/relay kits and chassis-specific part numbers.
- Confirm local requirements for installing and servicing A2L refrigerants (R-32).
