// Bottom Line

This Goodman 2-ton combo system works best for homeowners in moderate climates needing to replace aging equipment without premium pricing. The 80% AFUE efficiency and 14 SEER cooling deliver solid year-round performance, while the $2,071 price makes it accessible for budget-conscious contractors and DIY installers.

Review

The Goodman 2-ton combo system sits squarely in the mid-market segment, offering proven reliability without premium pricing. This upflow configuration combines an 80,000 BTU furnace with a 24,000 BTU cooling coil, making it suitable for homes up to 1,200-1,500 square feet depending on insulation and climate. At $2,071, it undercuts many name brands while maintaining Goodman's solid reputation among contractors.

Performance specs are straightforward. The furnace delivers 80% AFUE through a two-stage burner system, while the air conditioner reaches 14 SEER with a single-stage rotary compressor and R410A or R22 refrigerant capability. The variable-speed blower handles up to 2,000 CFM, adapting to different ductwork configurations. Electrical requirements are modest at 208/230V single-phase, requiring only 14.3 to 25 amps.

Pros & Cons

Pros

80% AFUE furnace with two-stage burner provides dependable heating for 80,000 BTU output

Cons

Single-stage condenser compressor is less efficient than dual-stage models in partial-load scenarios
Not Energy Star certified, meaning you miss potential rebates in some utility programs
80% AFUE is standard baseline efficiency, not the 95%+ available in high-efficiency units
71 dB noise level runs louder than premium inverter-driven competitors

Who Should Buy

Frequently Asked Questions

Can this system run on both natural gas and propane? +

Yes, the unit is designed for dual-fuel compatibility. Natural gas is standard, but propane can be used with minimal field conversion. Confirm your fuel type before installation and coordinate with your fuel provider for proper line sizing and regulator setup.

What ductwork size do I need for the 2,000 CFM airflow? +

You'll need return and supply ducts sized for approximately 400-500 CFM per ton. For a 2-ton system, plan for supply runs around 4-5 inches and return runs around 16x20 inches or equivalent. Have your HVAC contractor verify your existing ductwork against these specs.

How does 80% AFUE compare to newer high-efficiency furnaces? +

80% AFUE is standard mid-tier efficiency. High-efficiency models reach 95%+ AFUE using condensing technology. You'll see lower gas bills with premium units, but recovery time on the $1,500-2,500 extra cost depends on your climate and local energy rates.

Is the 14 SEER rating good for cooling performance? +

14 SEER is solid mid-market cooling efficiency, roughly equivalent to SEER2 11.5. Premium models reach SEER2 13+. For moderate climates, 14 SEER delivers measurable savings without the premium price tag of ultra-high-efficiency units.

Do I need to register the unit for the warranty? +

Yes, online registration is required to activate the full 10-year warranty. Registration is free and can typically be completed within minutes using your AHRI certificate number (204633307) and proof of purchase.
