// Bottom Line
This Goodman system is ideal for contractors and homeowners needing a straightforward 5-ton combo unit in climates requiring both cooling and heating. The 16 SEER2 rating and variable-speed blower keep operating costs reasonable, while the $2,071 price point sits well below premium brands without sacrificing core performance.

Review

Goodman's 5-ton gas furnace and heat pump combo targets the sweet spot between budget and performance. This horizontal configuration suits contractors working in tight spaces while delivering both heating and cooling from a single unit. At $2,071, it undercuts premium manufacturers, making it accessible for mid-range residential applications. The system carries AHRI certification number 204633307, confirming matched performance between components. Goodman's reputation for durability and parts availability has made them a contractor favorite for decades.

Cooling performance reaches 16 SEER2 with a two-stage scroll compressor and two-stage condenser, positioning it as Energy Star certified. The 60,000 BTU cooling capacity handles standard 5-ton loads. Heating delivers 60,000 BTU via a two-stage gas burner at 80% AFUE, accepting both natural gas and propane. The variable-speed blower modulates between 0 and 2000 CFM, reducing compressor short-cycling and lowering runtime noise. Electrical requirements call for 208/230V single-phase, 60Hz service with a 37.2 to 60-amp breaker range.

Pros & Cons

Pros

  • 16 SEER2 cooling efficiency with two-stage condenser matches or beats many mid-tier systems
  • Variable-speed blower motor adjusts airflow between 0-2000 CFM for comfort and reduced cycling
  • Two-stage gas burner with 60,000 BTU output allows modulation based on heating demand
  • Energy Star certified with available rebates further reducing out-of-pocket cost
  • Horizontal A-coil configuration suits tight attic or closet installations
  • 10-year warranty with online registration provides solid coverage for parts and labor

Cons

  • 80% AFUE heating efficiency is industry baseline, not premium, meaning higher heating bills in cold climates versus 95%+ AFUE systems
  • 75 dB noise level is moderately loud during operation, noticeable in finished spaces
  • R410A refrigerant phase-out beginning in 2025 may complicate future repairs or recharges

Who Should Buy

Best For

Contractors seeking reliable equipment for moderate-budget residential retrofits and new construction will appreciate Goodman's parts availability and straightforward specs. Homeowners in mixed climates wanting balanced heating and cooling without premium pricing find real value here.

Consider Alternatives If

Buyers in harsh winters should explore 90%+ AFUE furnaces to offset long heating seasons. Customers seeking ultra-quiet operation should compare units rated below 70 dB.

Installation

Horizontal configuration with A-coil design fits attics, basements, and mechanical closets where upflow won't work. Suction line uses 1 1/8 inch tubing with 1/2 inch insulation, while liquid line runs 3/8 inch sweat connections. Lineset extends 50 feet maximum. Metal exhaust flue venting is required. Variable-speed blower integration demands compatible ductwork calibration for rated airflow. Professional installation ensures proper refrigerant charge and gas pressure settings.

Warranty & Reliability

Coverage includes 10 years on all parts and components when registered online after purchase. Labor warranty terms depend on installer agreements. This positions Goodman competitively against mid-tier brands offering similar timeframes. Registration is straightforward and essential, as unregistered units default to shorter coverage periods.

Frequently Asked Questions

How does 16 SEER2 compare to other 5-ton systems in this price range? +
16 SEER2 performs solidly for budget-oriented packages. Entry-level competitors like basic Ruud or Rheem models sit around 14-15 SEER2, while Lennox or Carrier premium lines exceed 18 SEER2. This Goodman offers the sweet spot, beating cheaper alternatives without premium pricing.
Can this unit work with my existing ductwork? +
Maybe. The 2000 CFM maximum airflow is standard for 5-ton units, but your ducts must be sized correctly. Undersized ducts restrict airflow and reduce efficiency. Have an HVAC tech perform a Manual D calculation before installation to confirm compatibility.
Why is 80% AFUE considered standard rather than efficient? +
AFUE measures how much fuel converts to heat. At 80%, one-fifth of gas energy escapes unused. Modern high-efficiency units hit 95%+ AFUE, cutting heating costs significantly over time, especially in northern climates where furnaces run 6+ months yearly.
Is this better than a heat pump only system without gas backup? +
It depends on climate. This combo handles cold winters effectively with gas backup. Pure heat pumps struggle below 35 degrees Fahrenheit, requiring expensive resistive heating. In mild climates, heat pump only makes sense; in cold zones, this dual-fuel approach wins.
What does online registration actually unlock for warranty? +
Registration activates the full 10-year parts coverage. Without it, you're limited to shorter terms. The process takes minutes online and protects your investment, so do it immediately after installation.
