// Bottom Line
This Goodman system works best for homeowners in temperate regions needing reliable heating and cooling without premium pricing. The 13 SEER rating and 80% AFUE deliver solid year-round efficiency for mid-range budgets, though it won't match high-efficiency systems in energy savings.

Review

The Goodman 5-ton gas furnace and air conditioner combo represents the practical middle ground in HVAC systems. It delivers solid performance for homeowners who need both heating and cooling without paying for premium efficiency tiers. This upflow configuration handles standard residential applications well, making it a popular choice for replacement jobs where space constraints exist and budgets run moderate.

Performance specs show a 60,000 BTU cooling capacity at 13 SEER efficiency and 100,000 BTU heating output at 80% AFUE. The two-stage burner reduces short cycling during mild weather, while the high-efficiency multi-speed blower moves up to 2,000 CFM. A reciprocating compressor handles single-stage cooling. These numbers deliver respectable comfort in moderate climates but trail modern 16+ SEER and 95% AFUE competitors in efficiency metrics.

Pros & Cons

Pros

  • Two-stage burner heating with 100,000 BTU output reduces temperature swings and improves comfort
  • 13 SEER cooling efficiency balances performance with affordability for moderate climates
  • High-efficiency multi-speed blower motor with 2,000 CFM maximum airflow optimizes comfort and dehumidification
  • Compact footprint (30 by 21 by 21 inches) fits standard closets and utility spaces
  • 10-year warranty with online registration provides meaningful protection at this price point

Cons

  • 80% AFUE falls below modern 95% AFUE standards, costing more in heating fuel over the system's life
  • Single-stage compressor in AC section lacks variable capacity, cycling on and off rather than modulating
  • 77 dB noise level is audible and louder than some competing mid-tier models
  • Not Energy Star certified, missing qualification for many rebate programs

Who Should Buy

Best For

Homeowners replacing older systems in moderate climates who prioritize upfront affordability and reliable performance. Contractors installing affordable combos for price-conscious customers who don't need premium efficiency ratings.

Consider Alternatives If

Buyers in cold climates needing maximum heating efficiency, homes with tight budgets for utility bills, or those seeking ENERGY STAR certification for tax credits.

Installation

Installation requires standard refrigerant lines (3/8 inch liquid, 7/8 inch suction with 3/8 inch insulation), a metal exhaust flue, and 120V single-phase 60Hz power. Breaker sizing runs between 32.8 and 45 amps. The compact 30-pound condenser unit suits both upflow and downflow configurations, though placement with adequate clearance simplifies service access.

Warranty & Reliability

The 10-year parts warranty applies when you register the system online, offering solid coverage for compressor failure, heat exchanger damage, and component defects. This warranty length matches competitor offerings at this price tier. Coverage excludes labor and refrigerant, which contractors handle separately.

Frequently Asked Questions

What makes the two-stage heating better than single-stage? +
Two-stage burners fire at partial capacity during mild heating days, reducing on-off cycling and temperature swings. This improves comfort and reduces heating runtime during shoulder seasons. The 100,000 BTU output still delivers full capacity on the coldest days.
Will this system fit in my existing closet? +
The 30 by 21 by 21 inch dimensions fit standard utility closets and compact spaces. Verify existing ductwork connections and allow 12 inches clearance on the service side for filter changes and future maintenance access.
How does 13 SEER compare to newer systems? +
13 SEER provides good cooling efficiency for moderate climates but lags behind 16-18 SEER systems. Expect higher summer cooling bills than premium units. Rebates typically require 14+ SEER, so check local incentive programs before purchasing.
Can this system handle R410A and R22 refrigerant? +
Yes, the condenser accepts both R410A (modern standard) and R22 (older systems). Confirm your furnace coil compatibility before ordering. Mixed refrigerant types require matched charging, which affects installation cost.
What happens if I don't register the warranty online? +
The 10-year warranty requires online registration. Without registration, coverage defaults to shorter terms. Complete registration immediately after installation to activate full protection.
