Nortek is a lesser-known HVAC conglomerate that owns several brands including Gibson, Frigidaire HVAC, Westinghouse HVAC, and others. If you've encountered a Gibson or Nortek furnace quote and are comparing it to Goodman, here's what you need to know.
Who Is Nortek?
Nortek Global HVAC (now part of Nortek Inc.) manufactures furnaces and air handlers sold under multiple brand names including Gibson, Frigidaire (HVAC), Westinghouse (HVAC), and Tappan. These brands are largely the same manufactured product with different nameplates — a common practice in the HVAC industry. Goodman, by contrast, is a distinct Daikin-owned brand with its own manufacturing facilities.
Efficiency Comparison
| Feature | Goodman | Nortek/Gibson |
|---|---|---|
| AFUE Range | 80%–98% | 80%–96% |
| Top Model AFUE | 98% (GMVC98) | 96% |
| Two-Stage Models | Yes | Yes (select models) |
| Variable-Speed Blower | Yes | Limited |
| Modulating Models | Yes (GMVC98) | No |
Warranty Comparison
| Coverage | Goodman | Nortek/Gibson |
|---|---|---|
| Heat Exchanger | Lifetime (registered) | 20 years (varies) |
| Parts | 10 years (registered) | 5–10 years |
| Registration Required | Yes (60 days) | Yes |
Goodman's lifetime heat exchanger warranty is a significant advantage. For a component that costs $1,500–$3,000 to replace, this matters over a 20-year ownership period. See our guide on furnace warranty registration.
Parts and Serviceability
Goodman parts are stocked at virtually every HVAC supply house in Minnesota. Nortek/Gibson parts are less universally available and may require special ordering in some areas. In a Minnesota winter where furnace downtime is serious, parts availability matters. See our guide on where to buy Goodman furnace parts.
Market Position
Nortek/Gibson furnaces tend to occupy the contractor-installed budget segment and are not typically sold factory-direct. Goodman is available both through contractors and factory-direct through suppliers like Furnace Direct, where you avoid the dealer markup entirely. This makes Goodman's effective price-to-value ratio very competitive.
Which Should You Choose?
If a contractor is quoting you a Gibson or Nortek furnace at a price similar to Goodman, ask about the warranty, parts availability, and efficiency specs. In most cases, Goodman purchased factory-direct through Furnace Direct offers better warranty protection, wider parts availability, and higher efficiency options at a lower effective cost.
