// Bottom Line
This Goodman system excels for contractors and homeowners in cold climates prioritizing heating output and efficiency. The 100,000 BTU furnace with 96% AFUE paired with a 54,000 BTU, 16 SEER1 condenser makes it ideal for larger homes or regions with intense winters.

Review

This Goodman 5-ton split system represents solid mid-tier value for HVAC professionals and homeowners serious about heating performance. Combining a 100,000 BTU furnace with a 54,000 BTU condenser, it addresses the needs of larger homes or properties in regions where winters demand substantial output. Online Supply positions this as an ENERGY STAR qualified option with proven Goodman reliability, making it competitive against other conventional systems in its capacity class.

The heating side impresses with 96% AFUE and two-stage burner technology, meaning the furnace operates at partial capacity during mild winter days, reducing fuel consumption and improving comfort consistency. Cooling delivers 16 SEER1 efficiency through a scroll compressor and single-stage design, adequate for most residential applications. The variable-speed ECM blower motor caps airflow at 2000 CFM maximum, automatically adjusting speed to match demand rather than running constantly at full power. The 115V single-phase electrical requirement keeps installation straightforward for standard residential wiring.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency reduces heating costs in colder climates significantly
  • Two-stage burner allows modulating heat output, improving comfort and reducing fuel waste
  • 16 SEER1 cooling efficiency exceeds ENERGY STAR requirements for better AC performance
  • Variable-speed ECM blower motor optimizes airflow and reduces electricity consumption
  • Scroll compressor design offers proven reliability and quieter operation than reciprocating models
  • PVC exhaust compatibility simplifies venting in retrofit and new construction scenarios

Cons

  • 73 dB operating noise is louder than high-end competitors, potentially noticeable in quieter homes
  • Single-stage cooling condenser cannot modulate capacity like two-stage units, reducing efficiency in mild weather
  • Requires 29.6 to 50 amp electrical service, necessitating upgraded panels in older homes

Who Should Buy

Best For

Contractors building systems in colder regions and homeowners in climates where heating season dominates budget concerns. This unit rewards homes with strong heating demands and those seeking ENERGY STAR compliance at reasonable cost.

Consider Alternatives If

Buyers in consistently mild climates should consider units with two-stage cooling to maximize summer efficiency, and anyone needing whisper-quiet operation should audition quieter models first.

Installation

This upflow configuration suits most standard installations in basements or utility closets. The A-coil style integrates cleanly with furnace plenum setups. Refrigerant lines measure 3/8 inch liquid and 1 1/8 inch suction with 50 feet of included insulation. PVC exhaust venting simplifies ductwork runs compared to metal pipes. Professional installation remains recommended for electrical connections, refrigerant charging, and proper airflow certification.

Warranty & Reliability

Goodman backs this unit with a generous 10-year parts warranty upon online registration, covering compressor, coil, and furnace components. This extended protection reflects manufacturer confidence and provides meaningful cost protection against premature failures. Registration is straightforward and strongly recommended, as it activates the full warranty term.

Frequently Asked Questions

What does 16 SEER1 cooling efficiency actually mean for my monthly electric bill? +
SEER1 measures cooling efficiency; higher numbers mean lower electricity use. At 16 SEER1, this condenser uses roughly 15 to 20 percent less power than 13 SEER units. Exact savings depend on climate and usage patterns, but expect meaningful reductions in humid or hot regions.
Can I upgrade from my old R22 refrigerant system to this unit? +
Yes, this system accepts either R410A or R22 refrigerant, offering installation flexibility. However, R22 systems are phased out, so new installations should use R410A. Your HVAC contractor will confirm compatibility and charge accordingly during setup.
How much does the two-stage furnace burner actually help during winter? +
Two-stage burners run at reduced capacity on mild winter days, cutting fuel consumption and heat delivery cycles. This improves temperature consistency and reduces on-off cycling, translating to lower heating bills and better comfort in variable winter weather.
Should I choose this over a higher SEER2-rated unit for cooling? +
If heating dominates your climate, this furnace priority makes sense economically. In balanced or cooling-heavy regions, compare total-system cost against two-stage cooling units. SEER2 ratings are newer metrics, so verify compatibility with online specification sheets before deciding.
What happens if I don't register the warranty online? +
Without registration, warranty coverage defaults to a shorter standard period. Always register immediately after installation to activate the full 10-year protection on parts.
