// Bottom Line
This Goodman 5-ton system suits contractors and homeowners upgrading mid-sized homes, particularly in regions with moderate heating demands. The 96% AFUE furnace and 16 SEER air conditioner balance operational costs with upfront affordability, though expect mid-tier brand reliability rather than premium durability.

Review

Goodman's 5-ton upflow gas furnace and air conditioner system positions itself as a practical middle-market choice for residential HVAC replacement. The combination of 120,000 BTU heating capacity and 54,000 BTU cooling capacity targets homes in the 2000 to 3500 square foot range. Sold through Online Supply and backed by a 10-year warranty with registration, this unit competes directly with other Goodman offerings and similar-tier brands like Amana. It's engineered for straightforward installation and long-term operation in standard residential configurations.

The 96% AFUE furnace rating means 96 cents of every heating dollar converts to usable warmth, among the highest standards for gas furnaces. The 16 SEER air conditioner delivers strong cooling efficiency for its price point, qualifying for ENERGY STAR rebates in many states. Two-stage burner modulation and an ECM multi-speed blower motor let the system adjust output to actual demand rather than cycling on and off constantly. Electrical requirements are modest at 29.6 to 50 amps on 208/230V single-phase, compatible with most home service panels.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency recovers more heat than most competitors, reducing winter energy waste significantly
  • 16 SEER cooling efficiency qualifies for ENERGY STAR, lowering summer cooling costs in warm climates
  • Two-stage burner and ECM multi-speed blower allow the system to modulate output, improving comfort and reducing short-cycling
  • Plastic/PVC exhaust flue compatibility simplifies venting in homes without existing metal flues
  • 2000 CFM maximum airflow handles 5-ton cooling and heating capacity without requiring oversized ductwork

Cons

  • Single-stage condenser means the air conditioner runs at full capacity or off, reducing efficiency in mild weather months
  • 73 dBA noise level is moderate to loud for some residential applications, especially during heating ramp-up
  • R410A refrigerant compatibility limits future repairs if R22 systems are phased out in your region

Who Should Buy

Best For

Contractors installing complete systems in mid-sized residential homes (2000-3000 square feet) and homeowners seeking efficient heating and cooling without premium pricing. The two-stage furnace and ECM blower appeal to those prioritizing comfort and utility bill reduction.

Consider Alternatives If

Buyers prioritizing ultra-quiet operation or those in very small homes where 5-ton capacity exceeds actual load requirements should explore smaller systems or higher-tier brands with variable-speed compressors.

Installation

Installation demands standard HVAC skills and tools. The upflow configuration suits most basement or utility closet placements. PVC exhaust venting simplifies routing compared to metal flues, reducing installation time and cost. Refrigerant line sets require proper brazing and evacuation; suction line insulation thickness is 0.5 inches. Technicians should verify ductwork matches the 2000 CFM maximum airflow to prevent static pressure issues. A qualified installer should handle all connections.

Warranty & Reliability

Ten-year parts warranty requires online registration after purchase. Coverage applies to manufacturer defects in the furnace and air conditioner components. Labor and refrigerant are typically excluded, so actual out-of-pocket repair costs vary by service provider and failure type. Extended warranties are often available at purchase for an additional fee, protecting against compressor failure.

Frequently Asked Questions

How much heating does the 120,000 BTU furnace actually deliver? +
All 120,000 BTU input doesn't reach your home because of combustion losses. With 96% AFUE, approximately 115,200 BTU of useful heat output occurs, meaning 4,800 BTU is lost through exhaust. This efficiency ratio significantly reduces winter natural gas consumption compared to older 80-85% AFUE units.
Can I install this system myself? +
No. Gas furnace and air conditioner installation requires EPA refrigerant certification, gas line testing, and electrical connections. Improper installation voids warranty and creates safety hazards. Hire a licensed HVAC contractor for complete system setup and startup commissioning.
Is 16 SEER good cooling efficiency? +
Yes. 16 SEER ranks as good efficiency for a mid-market system. It's notably better than minimum 13 SEER standards and qualifies for rebates. However, premium brands reach 18-20+ SEER with variable-speed compressors. At 16 SEER, expect solid performance without top-tier energy savings.
How does this compare to a Bryant or Carrier 5-ton system? +
Goodman systems typically cost 15-20% less than Bryant or Carrier equivalents because they use shared parent-company designs with simpler branding. Performance metrics match well, but Bryant and Carrier often provide better regional support and slightly longer component warranties.
What if my furnace fails after year five? +
Parts are covered under the 10-year warranty at no cost. You pay labor and any refrigerant needed. Service calls typically run $150-300 for diagnostics. Extended warranties available at purchase can cover labor costs for compressor or heat exchanger failure.
