// Bottom Line
This system works best for homeowners replacing aging equipment who want proven Goodman quality without premium pricing. The 80% AFUE furnace and 16 SEER2 condenser deliver solid efficiency for moderate climates, and the variable-speed blower helps with comfort control.

Review

Goodman has built its reputation on delivering dependable HVAC equipment at accessible price points, and this 3-ton combo system reflects that philosophy. At $2053, you're purchasing a complete gas furnace and air conditioner package featuring the company's proven scroll compressor technology and two-stage burner design. The upflow A-coil configuration suits homes with basements or crawl spaces where ductwork feeds upward through the structure.

The numbers tell a practical story. The furnace generates 80,000 BTU of heating with 80% AFUE efficiency, while the AC condenser delivers 34,800 BTU of cooling at 16 SEER2. The variable-speed blower motor adjusts between 0 and 2000 CFM, meaning the system doesn't blast air constantly but modulates output to match actual demand. Running on 120V single-phase power, it fits standard residential electrical infrastructure without upgrade costs. Scroll compressor technology keeps noise to 73.5 dB, roughly equivalent to a dishwasher.

Pros & Cons

Pros

  • 16 SEER2 cooling efficiency qualifies for Energy Star, reducing utility costs versus 13-14 SEER systems
  • 80% AFUE furnace with two-stage burners provides flexible heating output and better modulation than single-stage units
  • Variable-speed blower motor adjusts CFM up to 2000, improving temperature consistency and air distribution
  • Two-stage compressor and burner design reduces runtime waste and extends equipment lifespan
  • 10-year warranty with online registration covers parts and labor on most components
  • Scroll compressor technology delivers quieter operation at 73.5 dB compared to rotary alternatives

Cons

  • 80% AFUE trails newer condensing furnaces at 95%+ efficiency, costing more to operate long-term
  • Single-stage AC condenser cannot modulate cooling capacity, cycling on and off rather than ramping smoothly
  • Metal exhaust flue requirement adds installation complexity for some upflow configurations
  • R410A refrigerant phase-out beginning 2025 may limit future servicing options

Who Should Buy

Best For

Budget-conscious homeowners in moderate climates replacing older split systems or furnaces where the $2053 price point beats comparable Lennox or Carrier units. Contractors installing systems in rental properties or value-tier residential projects will appreciate the straightforward two-stage design and Goodman's solid service network.

Consider Alternatives If

Anyone in severe climates needing 95%+ AFUE efficiency, or those prioritizing variable-capacity cooling for premium comfort should explore condensing furnaces and dual-stage compressors instead.

Installation

Installation requires a metal exhaust flue for the furnace, standard refrigerant lines sized at 3/8 inch for liquid and 7/8 inch for suction with 3/4 inch insulation, and electrical connections between 18.7 and 30 amps. The unit dimensions of 30 inches tall by 21 inches wide by 21 inches deep fit most utility closets. Technicians should verify AHRI certificate 204633302 compatibility with your existing indoor coil before ordering.

Warranty & Reliability

Goodman backs this system with 10 years of parts coverage when you register online, a meaningful commitment that beats some competitors' 5-year baselines. Coverage includes the compressor, furnace components, and evaporator coil, though labor may carry separate terms depending on your installer. Registration takes minutes and activates immediately upon system startup.

Frequently Asked Questions

How does 16 SEER2 compare to modern high-efficiency units? +
16 SEER2 meets Energy Star standards and cuts cooling costs roughly 15-20% versus 13 SEER legacy equipment. However, dual-stage compressors rated 18-20 SEER2 provide superior part-load efficiency in mild weather, reducing cycling losses. Choose 16 SEER2 if budget is primary, upgrade if you live in hot climates where the AC runs frequently.
Will this fit my upflow basement installation? +
Yes. The unit measures 30 inches tall, 21 wide, and 21 deep, fitting standard utility closets. You'll need vertical ductwork clearance above and a metal flue to outside. Confirm your basement access width allows moving the 30-pound condenser through doorways during installation.
Does the two-stage burner really save money versus single-stage? +
Yes, in most climates. Two-stage burners run at reduced capacity during mild weather, cutting furnace runtime and gas consumption. In heating-dominated regions, this can lower seasonal heating costs 10-15% versus non-modulating units that cycle on at full output.
How does this compare to Lennox or Carrier systems at similar price points? +
Goodman typically undercuts both brands by 10-15% on identical SEER2 and AFUE ratings. You sacrifice some brand prestige and dealer networks, but performance specs remain competitive. Carrier's comparable 16 SEER2 unit often costs $300-500 more for identical efficiency.
What happens if I don't register the warranty? +
Goodman limits unregistered systems to 5 years parts coverage instead of 10. Registration is free and takes minutes online, so activate it before your installer leaves to secure full protection.
