2.5 Ton 13 SEER 96% AFUE 60,000 BTU Goodman Gas Furnace and Air Conditioner System - Horizontal Review 2026

// Bottom Line

This horizontal A-coil system works well for homeowners upgrading existing single-stage setups in modest-sized homes up to 2,500 square feet. It's best suited for straightforward installations where contractors have standard PVC exhaust venting and adequate electrical service already in place.

Review

Goodman's 2.5-ton horizontal system represents straightforward HVAC engineering without unnecessary complexity. At its price point, this unit competes directly against other single-stage combos from carriers like Lennox and Payne. The horizontal A-coil configuration targets attics and basements where vertical space is limited. This is not a premium offering, but rather a practical choice for contractors managing budget-conscious replacement jobs.

The 96% AFUE furnace rating puts heating efficiency well above 90% federal minimums, handling 60,000 BTU heat output effectively for moderate-sized homes. Cooling performance hits 13 SEER with 30,000 BTU capacity, matching industry middle ground rather than exceeding it. The single-stage reciprocating compressor operates consistently but lacks the modulation efficiency of two-stage or variable designs. Multi-speed blower control helps compensate with better temperature management across different demand levels.

Pros & Cons

Pros

96% AFUE furnace efficiency delivers solid heating performance with minimal gas waste
13 SEER cooling rating provides reasonable air conditioning efficiency at mid-market tier
Multi-speed blower motor allows better temperature control and quieter operation during partial loads
Compact horizontal configuration at 34.5" height fits tight attic or basement spaces
10-year warranty with online registration covers both heating and cooling components

Cons

Single-stage compressor and burner limit efficiency gains compared to modulating competitors
73 dB noise level runs noticeably louder than variable-capacity systems during cooling
R410A and R22 refrigerant compatibility may complicate service if older R22 system remains nearby
1200 CFM maximum airflow suits smaller homes, potentially undersized for larger open-concept layouts

Who Should Buy

Best For

Contractors replacing worn-out 2.5-ton systems in established homes where horizontal mounting is necessary. Homeowners in moderate climates seeking honest efficiency ratings without premium pricing for variable-stage technology.

Consider Alternatives If

Anyone prioritizing whisper-quiet operation, maximum cooling efficiency, or future-proof high-capacity systems should explore SEER 15+ and variable-stage alternatives.

Installation

This unit requires PVC exhaust venting and 115V single-phase 60Hz electrical service with 16.7 to 25 amp breaker capacity. Standard sweat-connection refrigerant lines use 3/8 inch liquid and 3/4 inch suction piping. Horizontal mounting demands careful condensate drainage planning. Most qualified contractors complete installation in 4-6 hours for straightforward replacements without complications.

Warranty & Reliability

Goodman backs this system with 10 years of parts coverage when you register online after purchase. Coverage includes compressor, blower motor, and heat exchanger against manufacturing defects. Online registration is mandatory to activate full protection, so contractors must ensure homeowners complete this step immediately after installation.

Frequently Asked Questions

How does 13 SEER cooling compare to newer air conditioners? +

13 SEER meets current federal minimum efficiency standards but trails premium units at 15-18 SEER. You'll see higher utility bills compared to variable-capacity systems, but performance remains reliable for moderate climates. Expect roughly 13-15% higher cooling costs versus SEER 16+ equipment.

What electrical work does a horizontal installation require? +

Standard 115V single-phase service requires a dedicated 20-25 amp breaker and proper grounding. Most homes built after 1990 already have suitable electrical panels. Have a licensed electrician verify breaker availability before ordering to avoid costly rewiring surprises.

Is 96% AFUE furnace efficiency worth the upgrade? +

Yes. 96% AFUE extracts significantly more heat from gas compared to 80-90% older units. Annual heating cost savings typically range from 15-25% depending on climate severity. This efficiency pays for itself through energy savings over the system's 15-20 year lifespan.

Can I replace my existing system with this horizontal unit? +

Yes, provided your current system uses compatible dimensions and ductwork. The 34.5-inch height fits most attic spaces. Have your contractor verify CFM capacity matches your home's duct system. Wrong sizing creates poor airflow and comfort problems.

What happens if I don't register for warranty coverage? +

Without online registration, Goodman limits warranty to 5 years instead of 10. Registration takes 10 minutes and protects your investment fully. Most contractors handle this during startup, but verify completion before leaving the job site.
