Review
The Goodman GMVM971005CN represents a practical middle-ground HVAC solution for homeowners and contractors seeking reliable, efficient heating and cooling without premium-brand pricing. This combination unit pairs a high-efficiency gas furnace with a two-stage air conditioner condenser in a compact upflow A-coil configuration. Goodman's reputation for straightforward engineering and parts availability makes this system accessible to a wide range of installers and serviceable across the country. The Energy Star certification signals genuine efficiency above baseline standards.
Performance specs are genuinely impressive for the price point. The furnace delivers 100,000 BTU of heating with 97% AFUE efficiency, meaning nearly all fuel converts to usable heat. The cooling side provides 35,000 BTU with an 18 SEER2 rating, though marketing materials reference 17 SEER. The modulating burner continuously adjusts flame to match heating demand rather than cycling on-off, reducing energy waste and noise. The scroll compressor operates in two stages, running at lower capacity during mild days. Variable-speed ECM blower technology on the furnace side optimizes air delivery across multiple operating conditions.
Pros & Cons
Pros
- 97% AFUE furnace efficiency means only 3% of fuel energy is wasted, translating to measurable heating cost savings
- 18 SEER2 rating on the condenser outperforms the advertised 17 SEER specification, providing better cooling efficiency
- Modulating burner and variable-speed ECM blower automatically adjust output to match demand, reducing short cycling and improving comfort
- Two-stage scroll compressor runs at reduced capacity most of the time, quieter operation at 71 dB(A) and lower wear
- Energy Star certified with rebate availability in many utility districts, offsetting initial investment
Cons
- Spec discrepancy: product title claims 17 SEER but specs list 18 SEER2, creating confusion about actual performance rating
- Price listed as $0 prevents meaningful value assessment against competing Goodman or Lennox alternatives
- No mention of variable-speed condenser fan, only two-stage compressor, which limits part-load cooling efficiency potential
Who Should Buy
Best For
Homeowners in northern climates with furnace-dominant heating needs who want efficiency improvements without high-end system costs. Contractors replacing units for price-conscious customers who value Goodman's warranty support and parts availability.
Consider Alternatives If
Anyone needing premium single-stage cooling performance or those in mild climates where AC runtime doesn't justify the investment should compare to single-stage alternatives.
Installation
Installation requires a licensed technician due to gas line connections and venting requirements. The unit is rated for 115V single-phase 60Hz power with breaker sizing between 21.9 and 35 amps, making electrical requirements straightforward. Dimensions of 34.5 inches tall by 21 inches wide by 28.75 inches deep work in most standard closets or basements. Flue location is right-side with plastic/PVC venting capability. Refrigerant connections use standard 3/8 inch liquid and 7/8 inch suction lines with sweat-type valves.
Warranty & Reliability
Goodman includes a 10-year limited parts warranty with online registration. This is industry standard for mid-tier systems and provides meaningful protection against compressor or heat exchanger failure during the critical first decade. Labor warranty typically requires separate service contract from your installer. Registration is straightforward and should be completed immediately after installation to activate coverage.
