2 Ton 15 SEER 96% AFUE 80,000 BTU Goodman Gas Furnace and Air Conditioner System - Upflow Review 2026

// Bottom Line

This Goodman system makes sense for homeowners replacing older 2-ton equipment in moderate climates where upflow installation works. The 96% AFUE furnace and 16 SEER cooling unit deliver solid efficiency without premium pricing, though the title lists 2 ton while specs show 3 ton tonnage, creating confusion you'll need to clarify before purchase.

Review

The Goodman 2-ton gas furnace and air conditioner system sits in the mid-range of the residential HVAC market, targeting homeowners seeking reliable performance without premium pricing. This unit combines a 96% AFUE gas furnace rated for 80,000 BTU heating output with a 16 SEER1 air conditioner handling 23,600 BTU cooling capacity. Priced at $2,666, it competes directly with builder-grade systems while offering efficiency ratings that satisfy Energy Star requirements and potentially qualify for utility rebates in many states.

The furnace operates at 96% Annual Fuel Utilization Efficiency, meaning 96 cents of every heating dollar directly heats your home rather than venting away. The two-stage burner adjusts between low and high fire for more consistent temperature maintenance. Cooling performance reaches 16 SEER1 efficiency through a scroll compressor paired with a variable-speed ECM blower motor capable of delivering up to 1,200 CFM. The blower's ability to modulate from minimum to maximum airflow independently reduces energy consumption during moderate cooling demand, offsetting the single-stage compressor's all-or-nothing operation.

Pros & Cons

Pros

96% AFUE furnace efficiency reduces heating costs substantially, qualifying for some state rebates
16 SEER1 cooling efficiency exceeds the 15 SEER rating claimed in title, delivering better AC performance
Variable-speed ECM blower motor automatically adjusts airflow from 0 to 1200 CFM, improving comfort and reducing runtime energy use
Two-stage burner modulates heat output, maintaining consistent temperature without temperature swings
$2,666 price point undercuts comparable Goodman systems by 15 to 20 percent at most retailers

Cons

Product title states 2 ton but specifications list 3 ton tonnage, creating significant confusion about actual cooling capacity
Single-stage compressor doesn't modulate cooling output, running full-capacity or off with no intermediate setting
71.5 dB noise level is moderately loud, potentially noticeable in quiet residential settings during operation

Who Should Buy

Best For

Homeowners in moderate climates replacing aged 2 or 3 ton systems who have vertical attic or basement space suitable for upflow A-coil installation. Budget-conscious buyers wanting solid efficiency without paying premium brand prices will appreciate the 96% AFUE and 16 SEER combination.

Consider Alternatives If

Anyone needing variable-capacity cooling should skip this model since the single-stage compressor cannot modulate, and buyers uncertain about upflow versus downflow configuration should consult an installer before committing.

Installation

This upflow A-coil system requires vertical installation, typically in an attic or basement closet with adequate headroom for the 34.5-inch height. The unit needs 115V single-phase 60Hz electrical service with a 12.4 to 20 amp breaker capacity, standard in most homes. Refrigerant lines connect via 3/8-inch liquid and 3/4-inch suction ports with 50 feet of insulated suction line included. PVC or plastic exhaust flue is required, which simplifies installation compared to metal vent requirements in some competitor models.

Warranty & Reliability

Goodman provides a 10-year parts and labor warranty when you register the unit online after installation. This extended coverage applies to defects in materials and workmanship, though coverage excludes maintenance-related failures. Ten years is industry-standard for mid-tier furnace systems. Registration is straightforward through Goodman's website, and Online Supply includes all warranty documentation in the product resources section.

Frequently Asked Questions

The title says 2 ton but specs show 3 ton. Which is correct? +

This discrepancy is a red flag you must resolve before purchasing. Cooling capacity is listed as 23,600 BTU and tonnage as 3 ton in the specifications, but the product title claims 2 ton. Contact Online Supply's sales team with the SKU (LS38343850) to confirm actual cooling capacity, as this significantly affects whether the system properly conditions your square footage.

Can this system use both R410A and R22 refrigerant? +

The specs list both R410A or R22 compatibility, but modern Goodman systems typically default to R410A. Verify refrigerant type with your installer before purchase, as mixing refrigerants or using the wrong type damages the compressor. R22 availability and cost have increased substantially, making R410A systems more practical for long-term ownership.

How does the variable-speed blower save energy? +

The ECM blower automatically adjusts speed from zero to 1,200 CFM based on heating or cooling demand. During light cooling loads, it runs at lower speeds, consuming less electricity than fixed-speed motors that run at full capacity regardless of need. This results in 10 to 15 percent energy savings for homeowners in moderate climates with seasonal temperature swings.

Should I choose this over a single-stage Lennox or Carrier system? +

Goodman's 96% AFUE and 16 SEER1 ratings match or exceed comparable Lennox and Carrier units at significantly lower cost. Lennox and Carrier typically charge 20 to 25 percent premiums for equivalent efficiency. Goodman reliability is solid, though some buyers perceive Lennox as higher quality. Contractor service availability varies by region, so verify local support before deciding.

What does the 10-year warranty actually cover? +

Goodman's registered 10-year warranty covers parts and labor for manufacturing defects and workmanship failures. It does not cover normal wear, maintenance neglect, improper installation, or refrigerant loss from leaks. Review the warranty document on Goodman's site for complete exclusions before purchase.
