3 Ton 17 SEER 80% AFUE 60,000 BTU Goodman Gas Furnace and Air Conditioner System - Upflow Review 2026

// Bottom Line

This Goodman combo system works best for homeowners upgrading from single-stage equipment who want measurable efficiency gains without premium pricing. The two-stage design cuts runtime and electric bills, making it ideal for moderate climates where heating and cooling seasons split the year.

Review

Goodman's 3-ton combo system sits solidly in the mid-market sweet spot where efficiency meets affordability. This unit pairs a two-stage 60,000 BTU furnace with a two-stage air conditioning condenser, Energy Star certified and built on proven Goodman engineering. At $2,645, it targets contractors and homeowners tired of paying premium prices for single-stage dinosaurs, yet unwilling to sacrifice real performance gains. The upflow configuration suits most residential installations without special modifications.

The cooling side delivers SEER1 18 efficiency using a scroll compressor and two-stage operation, though the spec sheet lists 17 SEER. Heating reaches 60,000 BTU at 80% AFUE, respectable for natural gas or propane applications. The variable-speed blower motor adjusts from minimal speed during mild days to full 1600 CFM capacity when demand peaks, reducing electricity waste. Two-stage design means the system runs at 50% capacity most of the time, only stepping to full output during extreme weather, extending equipment life noticeably.

Pros & Cons

Pros

SEER1 18 rating significantly outperforms the stated 17 SEER rating, delivering real cooling savings
Two-stage condenser and burner reduce short-cycling, improving comfort and component longevity
Variable-speed blower motor with 1600 CFM max airflow adapts to seasonal demands
80% AFUE furnace meets modern efficiency standards for natural gas and propane
10-year warranty with online registration covers parts and labor comprehensively

Cons

71 dBA noise level runs moderately loud during high-stage operation, noticeable to some users
Upflow/horizontal configuration limits flexibility for homes with basement or attic constraints
R410A and R22 refrigerant compatibility suggests potential older system integration rather than pure R410A focus

Who Should Buy

Best For

Contractors installing 3-ton systems in mixed-climate zones, and homeowners replacing 10-15 year old single-stage units. The efficient two-stage design and Goodman brand reliability make sense for someone prioritizing electricity savings over premium-tier SEER ratings.

Consider Alternatives If

Anyone needing SEER2 20+ or AFUE 95%+ should look at higher-tier systems, and homes with space constraints incompatible with 30-inch height upflow configuration should explore alternatives.

Installation

Installation demands standard 120V single-phase 60Hz power with 21.3 to 35 amp breaker capacity, typical for residential sites. The system uses sweat valve connections with 3/8-inch liquid line and 7/8-inch suction line, both standard for 3-ton equipment. Metal exhaust flue is required. Suction line insulation of 3/4-inch thickness comes factory-installed. Most licensed HVAC contractors complete installation in one day, including ductwork connections and refrigerant charging.

Warranty & Reliability

Goodman's 10-year parts and labor warranty applies with online registration, a straightforward process requiring SKU LS38783850 documentation. This coverage is solid for mid-market equipment, though not as extensive as some premium brands offering 12-year warranties. Registration is quick and essential to claim warranty benefits. Keep your receipt and installation documentation for any future claims.

Frequently Asked Questions

Why does the spec sheet list 17 SEER but the data shows SEER1 18? +

The product demonstrates SEER1 18 performance in testing, but marketing materials sometimes use conservative 17 SEER ratings. The AHRI certificate 204633301 will clarify exact ratings. You're getting better efficiency than the headline 17 SEER suggests.

Can this system replace my old R22 furnace and air conditioner? +

Yes, the R410A refrigerant is standard for new systems. The spec mentions R22 compatibility, likely for installer flexibility during transition. New installations use R410A exclusively. Confirm with your technician before purchase if replacing older equipment.

How much quieter is two-stage operation compared to single-stage systems? +

At 71 dBA full capacity, this matches many single-stage units. The advantage is runtime duration, not noise level. Two-stage systems run at lower BTU output 75% of the year, reducing overall noise exposure and energy consumption, though peak noise stays consistent.

Is 80% AFUE acceptable, or should I upgrade to 95% AFUE? +

80% AFUE is modern baseline, not outdated. High-efficiency models at 95% AFUE cost 40-60% more and require condensing exhaust systems. For most climates, 80% AFUE offers better payback periods than premium options unless you have extremely cold winters.

What does the 10-year warranty actually cover? +

Parts and labor for equipment failure under normal use, covered by online registration. It excludes maintenance, cosmetic damage, and improper installation. Keep documentation of professional installation to avoid disputes.
