Key Features

What sets the GPCH34831 apart

Built for Manufactured & Mobile Homes

Engineered specifically for manufactured and mobile home installations. Sized and configured for the typical ductwork, electrical service, and installation footprint of these home types — where standard residential split systems often don't fit cleanly.

All-in-One Package Design

Compressor, indoor coil, blower, and controls are all housed in a single outdoor cabinet — no separate indoor air handler required. Saves indoor floor space and simplifies installation.

Cooling + Optional Heat Kit

A cooling system with optional electric heat capability. Add a field-installable electric heat kit for supplemental heating, or pair with an existing heat source in your mobile home for year-round comfort.

R-32 Refrigerant

Built for R-32 — the next-generation residential refrigerant with lower environmental impact than R-410A. Requires less charge per system and meets current EPA and AIM Act phase-down requirements.

Single-Stage Scroll Compressor

A proven single-stage scroll compressor provides reliable, consistent cooling performance. Scroll technology is known for smooth operation, high efficiency, and long service life.

Backed by Goodman

Model GPCH34831. This 4-ton packaged air conditioner is part of the Goodman GPCH34831 from the GPCH3 R-32 series — a single self-contained outdoor unit using R-32 refrigerant. Rated at 13.4 SEER2 with 45,000 BTU/h cooling capacity. Features a single-stage compressor, multi-speed ECM indoor blower, all-aluminum evaporator coil, and copper-tube/aluminum-fin condenser coil with quiet horizontal discharge. Maximum voltage 230V single-phase.

  • Energy-efficient compressor — designed for efficient cooling operation.
  • Multi-speed ECM indoor blower motor — electronically commutated motor delivers steady airflow with lower electrical draw than legacy PSC motors.
  • Quiet horizontal discharge — horizontal-discharge airflow design.
  • Copper tube / aluminum fin condenser coil — outdoor coil construction for heat rejection durability.
  • All-aluminum evaporator coil — corrosion-resistant aluminum tube and fin construction on the indoor coil.

Why R-32 Refrigerant?

The GPCH34831 uses R-32 — here's how it compares to the outgoing R-410A standard

Feature R-32 (This Unit) R-410A (Old Standard)
Energy Efficiency Up to 10% higher Baseline
Refrigerant Charge Required Up to 30% less Standard

Frequently Asked Questions

What is a mobile home AC package unit?
A mobile home package unit houses the entire air conditioning system — compressor, indoor coil, blower, and controls — in a single outdoor cabinet sized specifically for manufactured and mobile home installations. Unlike a split system (which has separate outdoor and indoor units connected by refrigerant lines), everything is self-contained.
Why is this designed specifically for mobile homes?
Mobile and manufactured homes have different ductwork sizing, electrical service configurations, and installation footprints than traditional site-built homes. The GPCH line is engineered with these differences in mind — sizing, airflow, and connection points are tailored to common mobile/manufactured home layouts so installation is faster and more straightforward for your HVAC contractor.
Does this unit provide heat?
Not as shipped, but the unit accepts a field-installable electric heat kit for supplemental electric heat. The heat kit installs inside the package unit and kicks on when the thermostat calls for heat — ideal for the mild winter conditions typical in mobile home applications. For colder climates or homes where heat is the primary need, consider a Heat Pump Package Unit (GPHH series) instead, which heats and cools using a reversing valve.
AC package vs. heat pump package — which should I choose?
Choose an AC package unit if you already have a separate heating source (furnace, electric heat, etc.) and just need cooling — this tends to be the lower upfront cost option. Choose a heat pump package unit if you want one unit that handles both heating and cooling, or if you're in an all-electric home and want efficient electric heating. Your HVAC contractor can recommend the right fit based on your existing equipment and climate.
What size home does a 4.0-ton AC package unit serve?
A 4.0-ton mobile home AC unit is generally appropriate for mobile/manufactured homes in the 1,800–2,400 sq. ft. range, though climate zone, insulation, window area, and home layout affect sizing. A professional Manual J load calculation is the most accurate way to size cooling capacity for your specific home.
What do SEER2 and EER2 mean?
SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling efficiency across a typical cooling season — a higher number means lower electricity bills over the summer. EER2 measures efficiency at peak summer conditions (hot afternoon use) — useful if you're in a hot, humid climate where peak-demand efficiency matters. The GPCH34831 is rated at 13.4 SEER2 and 10.6 EER2.
What is R-32 refrigerant?
R-32 is the next-generation residential refrigerant replacing R-410A. It has lower environmental impact, requires up to 30% less charge per system, and offers improved energy efficiency. R-32 is being adopted industry-wide to meet EPA and AIM Act requirements phasing down legacy refrigerants.
Where does a mobile home package unit install?
Most mobile home package units install on a pad at ground level, adjacent to the home, with supply and return ductwork routing through the wall or floor into the home's existing ducts. Some installations use a rooftop platform. Your HVAC contractor will select the location based on ductwork access, electrical service, and local codes.
How do I register for the 10-year warranty?
Register the unit online at Goodman's warranty registration page within 60 days of installation. You'll need the model number (GPCH34831), serial number (from the data plate), installation date, and installing contractor information. Without timely registration, the warranty reverts to a shorter base term.
