// Bottom Line
This Goodman combo works best for budget-conscious homeowners in moderate climates who need reliable dual-fuel heating and cooling without premium pricing. It delivers solid efficiency gains over older systems at an accessible price point, though it won't compete with high-efficiency alternatives on operating costs.

Review

Goodman's 5-ton combination system sits comfortably in the practical middle of the residential HVAC market. This upflow configuration pairs a gas furnace with an air conditioning condenser, designed for homes requiring both seasonal heating and cooling. With a 14 SEER rating and 80% AFUE efficiency, it represents a meaningful step up from basic equipment while remaining accessible to budget-conscious buyers. Online Supply offers this unit as a complete package, simplifying the purchasing process for contractors and DIY homeowners alike.

Performance specifications tell a straightforward story of competent mid-range equipment. The cooling side delivers 60,000 BTU capacity through a single-stage scroll compressor, achieving 14 SEER efficiency without variable-speed technology. On heating, the two-stage burner produces 80,000 BTU at 80% AFUE efficiency. The high-efficiency multi-speed blower motor maxes out at 2000 CFM, allowing better modulation than single-speed alternatives. Electrical requirements fall between 32.8 and 50 amps at 120V, standard for equipment this size. Noise output registers 75 dB, noticeable but not unusually loud for traditional split systems.

Pros & Cons

Pros

  • 14 SEER rating provides meaningful cooling efficiency improvement over 13 SEER baseline units
  • Two-stage burner on furnace allows better part-load efficiency during milder winter days
  • High-efficiency multi-speed blower motor (max 2000 CFM) reduces runtime and energy waste
  • Compact A-coil footprint (30x21x21 inches) fits tight attic or closet installations
  • 10-year warranty with online registration covers both major components
  • Scroll compressor is proven technology with excellent reliability track record

Cons

  • 80% AFUE is mid-range, not best-in-class, meaning higher heating costs than 95%+ AFUE units
  • Single-stage condenser limits cooling efficiency at partial loads during shoulder seasons
  • R410A or R22 refrigerant compatibility creates uncertainty during installation and future servicing
  • 75 dB noise level is moderately loud, noticeable from adjacent rooms during operation
  • Not Energy Star certified, missing efficiency recognition and potential utility rebates
  • Requires 32.8 to 50 amp breaker, demanding proper electrical infrastructure

Who Should Buy

Best For

Homeowners replacing 10+ year old systems who want measurable efficiency gains without spending on premium models, particularly those in climates with balanced heating and cooling demands. Contractors installing budget systems for rental properties or cost-conscious customers who prioritize reliability over absolute efficiency.

Consider Alternatives If

Buyers in extreme climates needing aggressive heating or cooling, those seeking ENERGY STAR certification, or anyone unwilling to accept mid-range operating costs versus high-efficiency alternatives.

Installation

Installation demands standard skills and equipment. The 30x21x21 inch footprint fits most attic and utility closet spaces. Upflow/downflow flexibility accommodates various ductwork configurations. You'll need metal exhaust flue for the furnace, proper refrigerant line sizing with 3/8 inch liquid and 7/8 inch suction connections, and 3/8 inch suction line insulation. Electrical work requires proper breaker sizing between 32.8 and 50 amps. Most contractors complete installation within a single day.

Warranty & Reliability

Goodman extends 10 years of parts coverage when you register the system online. This protects major components including the compressor, furnace heat exchanger, and evaporator coil against defects. Registration is straightforward and critical for claim eligibility. Ten years falls behind industry leaders offering 12-year coverage, but matches most mid-tier competitors. Coverage begins from the installation date.

Frequently Asked Questions

How much will this system save me compared to my 10-year-old unit? +
The 14 SEER cooling and 80% AFUE heating represent solid efficiency gains. Compared to older 10 SEER and 78% AFUE equipment, you'll see roughly 15-20% annual HVAC energy reductions. Actual savings depend on your climate, usage patterns, and local electricity rates. Budget $150-300 annually in utility savings for moderate climates.
Will this fit in my existing ductwork? +
Likely yes, since this is a standard 5-ton system with 2000 CFM maximum airflow. The 30x21x21 inch dimensions suit typical attic and utility closet installations. Have a technician verify your ductwork can handle this CFM without creating excessive velocity. Older systems sometimes require minor duct adjustments.
Is 14 SEER good enough, or should I upgrade to 16+ SEER? +
14 SEER is solid for moderate climates with balanced heating and cooling loads. 16+ SEER units cost 20-40% more but only improve cooling efficiency by 15-20%. For warm climates with heavy cooling demand, the upgrade makes sense. For milder regions, 14 SEER delivers better value.
How does this Goodman compare to a Lennox or Carrier at similar price? +
Goodman competes on reliability and value, not premium features. Competitors at this price often offer similar SEER and AFUE ratings but sometimes quieter operation or better aesthetics. Goodman's scroll compressor is proven and durable. Real-world performance differences are minimal, so choose based on warranty terms and local service availability.
Do I need to register for the 10-year warranty? +
Yes, online registration is mandatory. Without it, warranty coverage drops to 5 years. Registration takes minutes through Goodman's website with your serial number. Keep the receipt and registration confirmation for service calls.
