// Bottom Line
This Goodman system works well for homeowners upgrading from older equipment or contractors building budget-conscious installs. The 92% AFUE furnace and 14 SEER air conditioner deliver solid efficiency without premium pricing, making it practical for mid-range residential applications.

Review

The Goodman 5-ton upflow system represents a straightforward approach to residential heating and cooling. It pairs a 100,000 BTU gas furnace with a matching air conditioner in a compact A-coil configuration, designed for homes averaging 2,000 to 2,400 square feet. Online Supply positions this unit as a value option for contractors and homeowners balancing performance with budget constraints. The upflow orientation suits basement or utility closet placement in most new construction and retrofit scenarios.

Performance numbers reveal a competent mid-range system. The furnace delivers 92% AFUE efficiency, meaning 92 cents of every heating dollar converts to usable warmth, a respectable figure for single-stage combustion. Cooling capacity reaches 60,000 BTU with 14 SEER efficiency, translating to roughly 14 BTU of cooling per watt consumed. The multi-speed blower motor supports airflow up to 1,600 CFM, enabling proper air distribution across ductwork. These specs won't rival premium systems, but they align well with homes seeking cost-effective climate control.

Pros & Cons

Pros

  • 92% AFUE furnace hits high heating efficiency for gas-fired systems, reducing winter fuel bills noticeably
  • 14 SEER cooling efficiency meets modern standards for decent summer performance across climate zones
  • 5-ton capacity handles most single-family homes up to 2,500 square feet without oversizing issues
  • Multi-speed blower motor allows flexible airflow matching, improving comfort and reducing noise
  • Single-stage scroll compressor design is durable and field-serviceable by most HVAC contractors
  • 10-year warranty with online registration provides meaningful protection on both components

Cons

  • Single-stage compressor and burner mean less modulation, so efficiency gains diminish in mild weather
  • 75 dBA noise level is moderate but noticeable, especially during heating cycle startup
  • Not Energy Star certified, so it misses rebate eligibility in some utility programs
  • R410A refrigerant requires proper recovery and handling, adding to service costs over time

Who Should Buy

Best For

Homeowners with homes between 1,800 and 2,500 square feet who want reliable performance without premium features or pricing. Contractors looking to balance efficiency ratings against customer budgets will find this system a practical middle-ground choice.

Consider Alternatives If

Anyone seeking Energy Star certification or variable-capacity equipment should look at higher-tier Goodman models or competitors like Lennox or Carrier.

Installation

Installation requires standard HVAC practices and materials. The unit needs a 32.8 to 50-amp electrical circuit at 115V, manageable on most residential panels. Refrigerant line sizing calls for 3/8-inch liquid and 7/8-inch suction lines with 3/8-inch insulation on the suction side. Gas hookup is straightforward single-stage burner work. PVC flue venting exits the right side, simplifying routing in attics or crawlspaces. Professional installation typically takes 4 to 6 hours.

Warranty & Reliability

Goodman covers this system for 10 years when registered online, a standard duration in the industry. Coverage includes compressor and furnace components, protecting against manufacturing defects. Registration is simple and typically completed at installation. Extended warranties are available from Online Supply if additional peace of mind matters to your buying decision.

Frequently Asked Questions

How does 14 SEER compare to newer SEER2 ratings? +
SEER2 tests under higher outdoor temperatures, typically showing 15 to 20 percent lower scores than SEER. This 14 SEER unit likely ranks around 11 to 11.5 SEER2 equivalent, still respectable but not cutting-edge. Regional climate affects real-world performance, with hot zones seeing better efficiency.
Can this system work with existing ductwork from an older unit? +
Yes, if the existing 5-ton or similar ductwork is in good shape. Verify duct sizing matches the 1,600 CFM maximum airflow and check for leaks, which rob efficiency. Professional duct testing before installation prevents airflow problems and ensures warranty protection.
What does 92% AFUE actually mean for my heating bills? +
92% AFUE means you lose only 8 percent of gas energy to exhaust and minor losses. On a $1,200 annual heating budget, expect to save roughly $60 to $100 yearly versus an 80% AFUE unit, depending on usage patterns and regional gas rates.
Is this better than budget brands like Frigidaire or Amana? +
Goodman and Amana share parent company Daikin, so component quality is similar. This unit's 92% AFUE and 14 SEER edge out Frigidaire's typical offerings. Goodman's parts availability through supply houses is a practical advantage contractors appreciate during service calls.
What happens to the warranty if I don't register? +
Standard Goodman policy voids online registration warranty benefits without registration. Contact Goodman directly at the time of installation or purchase to confirm current terms and registration procedures for your specific serial number.
