2 Ton 18 SEER 80% AFUE 60,000 BTU Goodman Gas Furnace and Air Conditioner System - Horizontal Review 2026

// Bottom Line

This Goodman system makes sense for homeowners replacing older equipment on a tight budget, particularly in mild to moderate climates where 80% AFUE meets code. At $1,909, you're getting respectable efficiency without premium pricing, though high-efficiency furnaces (95% AFUE) will save more on heating bills long term.

Review

The Goodman 2-ton horizontal gas furnace and air conditioner system lands in the practical middle ground of the HVAC market. At $1,909, it undercuts premium brands while delivering genuine two-stage efficiency on both heating and cooling sides. The horizontal configuration and compact 21-inch height make it ideal for retrofit installations where traditional vertical units won't fit. This SKU (LS38343850) is built for contractors and homeowners who need reliable performance without overbuying features.

Performance numbers tell the story here. The 18 SEER cooling rating and ENERGY STAR qualification mean measurable reductions in summer energy bills, while the 80% AFUE heating efficiency meets modern codes without premium pricing. The unit handles 60,000 BTU heating output and 23,000 BTU cooling through two-stage components, meaning it ramps down to part-load operation on mild days instead of cycling on and off. The variable-speed blower caps at 1,600 CFM, adjusting to match actual demand rather than running at fixed speed.

Pros & Cons

Pros

18 SEER cooling efficiency qualifies for ENERGY STAR, reducing summer electrical costs noticeably
Two-stage burner and two-stage condenser allow modulated operation, improving comfort and efficiency
Variable-speed blower motor adjusts airflow from 0 to 1,600 CFM, matching load precisely
Horizontal configuration fits tight attic or crawl space installations where vertical units won't work
10-year warranty with online registration provides solid protection on both heating and cooling components
$1,909 price point undercuts most comparable dual-fuel combos by $400 to $600

Cons

80% AFUE is baseline efficiency, not best-in-class, so heating fuel costs remain higher than 95% AFUE systems
23,000 BTU cooling capacity creates a slight tonnage mismatch (listed as 3.5 ton condenser but 2 ton system), which may indicate this pairs with a specific indoor coil
71 dB noise level is moderate, potentially audible in quiet neighborhoods during two-stage operation
Metal exhaust flue requirement adds installation cost and complexity versus direct vent options
R410A refrigerant compatibility limits future service flexibility as industry shifts toward low-GWP alternatives

Who Should Buy

Best For

Homeowners in HVAC zones 2-4 (mild to moderate winters) seeking cost-effective replacement of split systems or packaged units where space is limited. Contractors installing horizontal equipment in attics or tight crawlspaces will appreciate the compact 21-inch height and side-access design.

Consider Alternatives If

Anyone in cold climates (zones 5-7) should explore 95% AFUE furnaces instead, as the 15-point AFUE gap will cost thousands over 15 years. High-end homes or customers prioritizing whisper-quiet operation should look at premium lines with lower decibel ratings.

Installation

Installation requires a metal exhaust flue and proper 208/230V single-phase electrical service with 15.3 to 25-amp breaker capacity. The horizontal coil orientation demands careful ductwork planning and condensate drain routing. Refrigerant connections use 3/8-inch liquid and 3/4-inch suction lines with 3/4-inch insulation on the suction line. Most contractors complete this in 4 to 6 hours for experienced crews. Online Supply provides installation manuals and specification sheets as PDF resources.

Warranty & Reliability

Goodman extends a 10-year warranty when you register the unit online after purchase. Coverage applies to compressor, heat exchanger, and component failures, providing real peace of mind for $1,909 equipment. Registration typically takes five minutes and requires proof of purchase and installation date. This warranty is non-transferable, so residential homeowners get full benefits only if they stay in the home.

Frequently Asked Questions

Why does the specs show 3.5 ton condenser with 2 ton cooling? +

This unit is designed to pair with a specific 2-ton indoor coil and furnace. The condenser tonnage listing reflects the physical component, but the system operates as a true 2-ton unit with 23,000 BTU cooling capacity. Verify AHRI match (certificate 204633301) with your indoor equipment before purchasing to ensure proper pairing and efficiency ratings.

Can this handle propane instead of natural gas? +

Yes. The unit accepts both propane and natural gas with fuel-specific burner adjustments at installation. Your contractor will set orifices and pressures for your local fuel type. Propane systems may require additional tank sizing considerations, but the furnace itself handles both without modification.

How much will this save compared to a 95% AFUE furnace? +

In zone 5 climates, expect 15 to 20 percent higher heating fuel costs over 15 years. If natural gas costs $1.20 per therm and your home burns 600 therms annually, the 80% unit costs roughly $150 more per winter. Over 15 years, that approaches $2,250 in extra heating costs, offsetting the initial $400 to $600 savings.

Is 71 dB noise level acceptable for residential use? +

71 dB equals normal conversation volume, comparable to a dishwasher. During two-stage operation at 50 percent load, noise drops slightly. If your unit runs in a basement or garage with distance from bedrooms, it's acceptable. For upstairs attic installations near sleeping areas, consider sound wrap or premium units rated below 68 dB.

What does 18 SEER actually mean for my cooling bills? +

18 SEER means the unit delivers 18 BTU of cooling per watt consumed over a summer season. Compared to 10 SEER units from 15 years ago, you'll save roughly 40 to 45 percent on air conditioning electricity. Actual savings depend on local rates and cooling degree days, but expect $200 to $300 annual savings in moderate climates.
