About this system
The Goodman GPGM33606031 is a 3-ton, multi-positional gas/electric package unit combining a 60,000 BTU gas furnace section running at 81% AFUE with a 13.4 SEER2 cooling side charged with R-32 refrigerant. As a self-contained package unit, the entire system ships in one cabinet that mounts either on a rooftop curb or a ground-level slab and connects directly to your ductwork, making it a common choice for homes without a basement or indoor mechanical closet, manufactured housing, and light commercial spaces that need a single footprint for both heating and cooling.
The 13.4 SEER2 rating sits right at the current federal minimum efficiency threshold for most U.S. climate zones, so this is an entry-level efficiency choice rather than an energy-saving upgrade. The 81% AFUE heating section means roughly 19 cents of every dollar spent on gas escapes as exhaust, which is acceptable for mild-winter climates but noticeably less economical than 90%-plus condensing alternatives in colder regions. R-32 refrigerant is a meaningful step forward from older R-410A units in terms of lower global warming potential, and it is now common across the industry at this price tier. Multi-positional installation means the unit can be set up in downflow, horizontal, or upflow configurations, giving installers flexibility across different job-site conditions.
The GPGM33606031 is a straightforward, budget-conscious package unit that delivers baseline efficiency and a familiar installation footprint at a price point meaningfully below Carrier, Trane, or Lennox equivalents. It is not the most efficient or the most durable option on the market, but for homeowners who need a direct replacement without premium pricing and who have access to a competent installer, it does the job. Long-term ownership costs depend heavily on install quality and whether common weak points like dual-run capacitors and evaporator coils hold up past the mid-warranty years.
Overall score is the average of the five ratings above.
What we like
- Purchase price runs 15 to 25 percent below comparable Carrier, Trane, and Lennox package units
- All-in-one cabinet simplifies replacement jobs and keeps installation labor relatively straightforward
- R-32 refrigerant is a lower-GWP choice that aligns with evolving industry and regulatory direction
- Multi-positional design covers a wide range of application types, from rooftop commercial to slab-mount residential
- 10-year registered parts warranty is competitive for this price tier
Trade-offs
- 13.4 SEER2 is minimum-code efficiency, so monthly utility savings versus a mid- or high-efficiency unit are essentially zero
- 81% AFUE gas section is noticeably less efficient than 90-plus percent condensing alternatives, adding meaningful heating costs in cold climates
- Compressor lifespan averages 10 to 14 years in documented owner experience, shorter than the 15 to 20 years typical of premium brands
- Evaporator coil leaks and dual-run capacitor failures are the most frequently reported repair events, with repair costs typically rising after year 7
What homeowners and pros say about Goodman
Goodman carries a split reputation among homeowners and the technicians who service their equipment. On Google dealer reviews, Goodman-installed systems average around 3.8 out of 5, where the most consistent praise centers on affordability and the ability to get a working system installed without a significant financial strain. ConsumerAffairs tells a more cautious story, with scores hovering around 2.5 out of 5 on a platform that tends to attract owners who have already run into problems. The recurring theme there is repair costs that start climbing after roughly year 7, a timeline that aligns with the documented failure patterns for dual-run capacitors and evaporator coil leaks.
For this specific package unit, technicians tend to point out that the all-in-one cabinet is straightforward to drop in as a replacement and that the multi-positional design reduces the number of judgment calls during installation. The cautions they raise are consistent across the brand: make sure the refrigerant charge is verified with a gauge set, confirm airflow against the manufacturer specifications, and do not skip the startup checklist, since a meaningful share of first-year refrigerant leak reports trace back to installation or initial charge errors rather than product defects. Compressor longevity averaging 10 to 14 years versus the 15 to 20 years typical of premium brands is the honest long-term trade-off buyers are making when they choose this unit for its lower upfront cost.

What it costs to run
At 13.4 SEER2, cooling this 3-ton system for a typical 1200-hour cooling season at the U.S. average electricity rate of $0.17/kWh works out to roughly $548 per year in cooling, about $0 less per year than a minimum-efficiency 13.4 SEER2 unit of the same size. Your real cost depends on your climate and local rate.
Method: (36,000 BTU/hr ÷ 13.4 SEER2) × 1200 hours ÷ 1000 × $0.17/kWh. Rate source: U.S. EIA average; cooling hours: moderate-climate estimate.
How it compares
| Brand | Comparable model | SEER2 | Stage | Price position |
|---|---|---|---|---|
| Goodman | GPGM33606031 | 13.4 | Single-stage | Value pick |
| Carrier | WeatherMaster 50XC Series | 14.0 | Single-stage | Typically 15 to 25 percent higher than Goodman |
| Trane | Precedent XR13 Package Unit | 13.4 | Single-stage | Typically 15 to 25 percent higher than Goodman |
| Lennox | LRP16GE Package Unit Series | 16.0 | Single-stage | Noticeably higher than Goodman, reflecting higher efficiency tier |

Questions about this system
Can this unit really be mounted on a rooftop, or is it only for ground-level slab installation?
It is designed for both. The multi-positional cabinet is compatible with standard rooftop curb mounting as well as ground-level slab or downflow configurations. Your installer will need to confirm the correct duct connection orientation and any local code requirements for the mounting method you choose.
Is 81% AFUE good enough, or should I be looking at a higher-efficiency heating section?
For climates where winter temperatures rarely drop below freezing and heating represents a small share of your annual energy bill, 81% AFUE is workable. In colder regions where you run the heat for several months, the gap between 81% and a 90-plus percent unit will show up clearly on your gas bill over the years. Package units with condensing heat sections exist but cost more upfront.
What are the most common repairs I should budget for over the life of this unit?
Based on documented owner experience with Goodman equipment, dual-run capacitor failures are the most frequently reported issue and typically run 300 to 600 dollars to fix. Evaporator coil leaks appear in a meaningful share of reviews, and compressor replacement becomes a realistic possibility somewhere in the 10-to-14-year range. A service agreement that covers annual inspections can catch capacitor wear early.
Does R-32 refrigerant require any special handling or add complexity for future service calls?
R-32 requires technicians with updated equipment for handling, as it is mildly flammable (A2L classification) and calls for specific recovery and charging procedures. Most established HVAC service companies are already equipped for it, but it is worth confirming your service provider has R-32 capability before signing a maintenance contract.
How important is the installer when it comes to how long this unit will last?
Critically important. HVAC technicians consistently identify install quality as the single largest factor in Goodman equipment lifespan. Proper refrigerant charge, correctly sized ductwork, accurate airflow balancing, and secure electrical connections at startup are all areas where shortcuts lead to early failures, including some of the refrigerant leak reports that appear within the first year of ownership.
