// Bottom Line
This Goodman system works best for homeowners replacing older equipment on a tight budget or contractors needing a reliable package unit for modest-sized homes. At $643, you're getting proven technology with respectable efficiency ratings without breaking the bank.

Review

This Goodman 3-ton packaged system combines a gas furnace and air conditioner in one downflow-capable unit, addressing a real market need for budget-friendly replacements. At $643, it undercuts most comparable combos by 30 to 40 percent. The system delivers 36,000 BTU cooling and 80,000 BTU heating in a compact A-coil configuration measuring 30 by 17.5 by 21 inches. Goodman's reputation for straightforward reliability supports this entry-level offering.

Performance specs are where this unit shows its value proposition. The 14 SEER rating on the cooling side keeps utility bills reasonable without the premium cost of 16+ SEER models. The 80% AFUE gas furnace is adequate for most climates, though it misses Energy Star certification that would unlock state rebates. Single-stage operation means the compressor and burner run at full capacity even during mild weather, which is less efficient than modulating equipment but proven durable across decades of field use.

Pros & Cons

Pros

  • 14 SEER cooling efficiency matches mid-tier systems at budget pricing
  • 80,000 BTU gas furnace with 80% AFUE provides consistent heating for 3-ton capacity homes
  • Multi-speed PSC blower motor delivers up to 1,600 CFM for better airflow distribution
  • Single-stage scroll compressor is proven reliable architecture used across thousands of installations
  • 10-year warranty with online registration covers parts and labor defects

Cons

  • 80% AFUE is not Energy Star rated, missing potential rebates in many states
  • Single-stage burner and compressor mean less modulation on mild weather days
  • 73 dB noise level is on the higher end for residential equipment

Who Should Buy

Best For

Budget-conscious homeowners in moderate climates replacing 10+ year old systems, or contractors building starter packages for rental properties. This system delivers acceptable efficiency without premium pricing that can't justify itself in 5-year payback periods.

Consider Alternatives If

Anyone prioritizing Energy Star status or needing variable-stage compressors for superior part-load efficiency should explore alternatives like higher SEER models or units with variable-speed technology.

Installation

Installation is straightforward for experienced technicians familiar with downflow configurations. The unit requires metal flue exhaust from the top, 3/8 inch liquid lines with 3/4 inch insulation, and 3/4 inch suction lines. Electrical needs are modest, 120V single phase with breaker sizing between 18.7 and 30 amps. Supplied documentation includes CAPF installation manuals and specification sheets.

Warranty & Reliability

Goodman offers a 10-year warranty upon online registration, covering parts and compressor defects. This is industry-standard protection that rewards proper registration. Ten years typically aligns with system lifespan under normal maintenance, making this a meaningful safety net for buyers at this price point.

Frequently Asked Questions

What's the actual cooling capacity in BTU? +
The unit delivers 36,000 BTU of cooling capacity, which matches its 3-ton rating. This handles homes between 1,200 and 1,500 square feet depending on insulation, climate, and sun exposure. Verify proper sizing with load calculations before purchasing.
Can this system work with both R410A and R22 refrigerant? +
Yes, the system is compatible with both R410A and R22 refrigerant types. However, R22 is being phased out, so R410A is the practical choice for new installations. Confirm refrigerant type with your installer before delivery.
Is 80% AFUE furnace efficiency acceptable? +
80% AFUE is acceptable but not premium. It means 80 cents of every heating dollar converts to home warmth, with 20 cents lost through the flue. Higher-efficiency models reach 95% AFUE but cost significantly more. This unit suits budget-conscious buyers in moderate climates.
How does 14 SEER compare to newer standards? +
14 SEER is solid mid-tier efficiency, about 10 to 15 percent better than 13 SEER baseline units. It's not cutting-edge, but cooling costs are reasonable. Units with 16+ SEER cost substantially more and require longer payback periods to justify investment.
What does the 10-year warranty actually cover? +
The warranty covers manufacturing defects in parts and the compressor when you register online. It does not cover improper installation, maintenance neglect, or refrigerant loss. Keep service records to validate coverage if claims arise.
