// Bottom Line
This $762 system works best for cost-conscious homeowners upgrading older equipment or contractors stocking rental properties where upfront expense matters more than premium efficiency. The 80% AFUE furnace and 16 SEER cooling handle moderate climates adequately, though high-efficiency seekers should look elsewhere.

Review

The Goodman 2.5-ton combo system represents the accessible entry point in the residential HVAC market. At $762, this upflow furnace and air conditioner combination targets budget-conscious buyers and professional contractors who need dependable equipment without premium pricing. Goodman holds strong market share in the value segment, and this configuration is commonly found in retrofit applications where space constraints and cost control drive purchasing decisions.

Performance specs show the furnace delivers 100,000 BTU heating with 80% AFUE efficiency and two-stage burner operation. The air conditioning side provides 29,000 BTU cooling with an impressive 16 SEER1 rating, Energy Star certification, and R410A/R22 refrigerant compatibility. The scroll compressor operates at 71.5 dB, and the high-efficiency multi-speed blower reaches 2000 CFM maximum. Electrical requirements stay modest at 120V single phase, 17.1 to 25 amp breaker capacity.

Pros & Cons

Frequently Asked Questions

Why does the spec sheet list 3.5 tons when this is marketed as 2.5 tons? +
This appears to be a data discrepancy in the manufacturer specs. The 29,000 BTU cooling capacity aligns with 2.5-ton equipment (approximately 12,000 BTU per ton). Request clarification from the retailer before purchase to confirm actual tonnage.
Can I use this system in my existing home with older copper line sets? +
Yes, with proper refrigerant conversion. This unit supports both R410A and R22, making it compatible with legacy systems during retrofit. However, system flushing and oil compatibility checks are essential. Professional installation is strongly recommended.
How does 16 SEER1 compare to newer efficiency standards? +
SEER1 replaces the older SEER rating. A 16 SEER1 is respectable for entry-level equipment, roughly equivalent to older 13 SEER ratings. Modern premium units reach 18-22 SEER1, so this isn't cutting-edge but handles standard cooling adequately.
Is 80% AFUE furnace efficiency acceptable in 2024? +
80% AFUE meets minimum federal standards but isn't competitive. Modern mid-range units offer 90-95% AFUE, reducing heating costs by 10-15%. Consider this a budget option, not an upgrade for efficiency-focused homeowners seeking payback within 10 years.
What does the 10-year warranty actually cover? +
Parts coverage on manufacturing defects including compressor and heat exchanger. Labor and refrigerant aren't included. Registration is required to activate. Read the full warranty document before purchase to understand exclusions.
