5 Ton 15 SEER 96% AFUE 100,000 BTU Goodman Gas Furnace and Air Conditioner System - Upflow Review 2026

// Bottom Line

This Goodman system works well for homeowners replacing aging equipment in moderate climates or contractors seeking reliable, efficient dual-fuel capability. The 96% AFUE furnace and 16 SEER2 condenser offer solid energy savings without premium pricing, though the single-stage compressor means less fine-tuned comfort control than variable-capacity units.

Review

The Goodman 5-ton combination system bundles a furnace and air conditioner designed for straightforward residential installations. This upflow configuration fits standard closet or basement applications where space is limited. Goodman's reputation for durability and straightforward serviceability makes this system popular with both contractors and homeowners handling replacements. The unit arrives complete and ready for professional installation, with proper refrigerant charge and factory testing completed.

Performance specs tell a balanced story. The furnace delivers 100,000 BTU at 96% AFUE efficiency, meaning nearly all fuel converts to usable heat rather than escaping through venting. The air conditioner produces 54,000 BTU cooling capacity with 16 SEER2 rating, substantially beating the federal minimum of 13 SEER2. Variable-speed ECM blower motor adjusts airflow from 0 to 2000 CFM, reducing energy waste during partial-load conditions. Single-stage compressor limits modulation capability compared to two-stage alternatives.

Pros & Cons

Pros

96% AFUE furnace efficiency means lower heating bills, especially valuable in colder regions
16 SEER2 cooling rating significantly exceeds minimum standards, qualifying for rebates and Energy Star certification
Variable-speed ECM blower motor reduces runtime and electricity consumption compared to fixed-speed alternatives
Two-stage burner allows efficient part-load heating, adapting to mild weather without full-fire operation
Dual-fuel capability supports natural gas or propane, offering flexibility for retrofit installations

Cons

Single-stage cooling compressor provides less modulation than variable-capacity units, missing fine-tuned capacity matching
73 dB noise level is moderately loud, potentially noticeable during operation in quiet neighborhoods
Listed price of $0 appears to be placeholder data, masking true market cost for budget planning

Who Should Buy

Best For

Homeowners in transitional or cold climates wanting to cut heating costs through a reliable, high-efficiency furnace paired with solid cooling performance. Contractors installing split systems in existing homes who need flexible fuel options and proven Goodman reliability without overspending on variable-capacity features.

Consider Alternatives If

Buyers prioritizing whisper-quiet operation, variable-capacity modulation, or ultra-premium 18+ SEER cooling should evaluate competing options from Carrier or Lennox.

Installation

Upflow configuration requires ducting connection above the unit and return air below. Plastic PVC exhaust flue is mandatory and must meet local venting codes. Electrical service needs 115V single-phase 60Hz with 29.6 to 50 amp breaker. Refrigerant lines use standard 3/8 inch liquid and 7/8 inch suction copper tubing with 3/4 inch insulation, supporting up to 50 feet of line set. Professional installation is strongly recommended for proper charge, airflow, and safety compliance.

Warranty & Reliability

Ten-year parts coverage through Online Supply with registration, providing meaningful protection against manufacturing defects. Evaporator coil carries separate Goodman warranty extending protection on freeze-up and refrigerant leak scenarios. Coverage does not include labor, maintenance, or damage from improper installation. Registration is required to activate full benefits, so complete paperwork promptly after installation.

Frequently Asked Questions

How does 16 SEER2 cooling efficiency compare to typical air conditioners? +

SEER2 of 16 exceeds the current federal minimum of 13 SEER2 by approximately 23 percent, translating to lower summer electric bills. This rating qualifies the unit for ENERGY STAR certification and many utility rebates. Most standard 5-ton units range between 13 to 15 SEER2, so this sits in the upper-middle efficiency tier without venturing into premium two-stage territory.

Is this system suitable for propane heating in rural areas? +

Yes, the furnace accepts both natural gas and propane fuel, making it practical for properties without municipal gas lines. Propane operation requires a separate regulator and supply tank, typically installed by a qualified propane technician. Verify local codes allow propane furnaces before purchasing, as some jurisdictions have restrictions.

What does the variable-speed ECM blower actually save? +

ECM blowers reduce electricity consumption by 30 to 40 percent compared to fixed-speed motors by varying speed based on actual heating or cooling demand. Moderate weather operation uses partial speed, cutting unnecessary runtime. Annual blower electricity savings typically range 150 to 250 kilowatt-hours, depending on local climate and usage patterns.

Why choose single-stage cooling over variable-capacity? +

Single-stage compressors cost significantly less while still delivering solid cooling performance. Variable-capacity units modulate between 25 and 100 percent output for finer temperature control and lower dehumidification. Single-stage runs at full power or off. For most homeowners in moderate climates, single-stage provides adequate comfort at lower upfront cost.

Does registration truly matter for the 10-year warranty? +

Yes, Online Supply and Goodman require registration within 30 days of installation to activate the full 10-year parts warranty. Without registration, coverage may be limited to one year or denied entirely. Keep purchase receipts and proof of professional installation to support warranty claims.
