Review
Goodman remains a trusted equipment manufacturer for budget-conscious homeowners and contractors seeking solid efficiency without luxury pricing. This 3-ton system pairs a 100,000 BTU furnace with a 35,000 BTU air conditioning condenser in a horizontal A-coil configuration. The combination delivers both heating and cooling solutions in single equipment strategy, simplifying replacement projects and reducing installation complexity for experienced technicians.
The 97% AFUE furnace rating ranks among the highest efficiency gas furnaces available, converting nearly all fuel energy into usable heat. Its modulating burner adjusts output continuously rather than cycling full on and off, reducing temperature swings and improving comfort. The 18 SEER2 air conditioner with two-stage compressor and variable-speed ECM blower matches modern efficiency expectations while maintaining the scroll compressor reliability Goodman is known for. These ratings translate directly to lower utility bills, particularly in climates with extended heating seasons.
Pros & Cons
Pros
- Exceptional 97% AFUE heating efficiency reduces natural gas consumption and monthly heating costs significantly
- 18 SEER2 cooling rating substantially outperforms standard 13-14 SEER systems, earning Energy Star certification
- Modulating burner stages optimize comfort by adjusting heat output to actual demand rather than cycling on and off
- Variable-speed ECM blower motor adjusts airflow intelligently, improving comfort and reducing fan noise at 71 dBA
- Two-stage scroll compressor with R410A/R22 compatibility provides system flexibility and reliable cooling performance
Cons
- Price listed at $89 appears incomplete, likely reflecting coil cost only without installation labor or complete system components
- Horizontal configuration limits placement options, requiring adequate attic or crawlspace height of at least 21 inches
- 10-year warranty requires online registration, adding a step that some homeowners may overlook
Who Should Buy
Best For
Homeowners in climates with significant heating and cooling demands who can accommodate a horizontal unit in their attic or crawlspace. This system suits those replacing 10-15 year old equipment and wanting measurable energy savings without ultra-premium pricing.
Consider Alternatives If
Buyers with space constraints or those needing a vertical upflow configuration should explore alternative unit orientations, as the horizontal-only design won't fit all installations.
Installation
This horizontal unit requires attic or crawlspace installation with minimum 21-inch clearance. Technicians must run 3/8-inch liquid line and 7/8-inch suction line with 3/4-inch insulation to outdoor condensers. The unit accepts both natural gas and propane, requiring proper fuel line connection and venting through plastic or PVC exhaust flues. Electrical connection needs 115V single-phase 60Hz service with 21.3 to 35-amp breaker capacity.
Warranty & Reliability
Goodman backs this system with a 10-year parts warranty following online registration at purchase. This protection covers defects in materials and workmanship, providing meaningful security for component failures. Registering immediately after installation ensures no coverage gaps and establishes documentation for future service claims or warranty transfers if you sell the home.
