Yes—Goodman is owned by Daikin Industries, the world’s largest HVAC manufacturer. Since 2012, both brands have shared:
- Manufacturing plants in the U.S.
- Engineering platforms (same coils, compressors, and internal parts)
- Dealer and warranty systems
However, Daikin is positioned as the premium brand, while Goodman is designed for value-focused homeowners. Think of it like Toyota vs. Lexus—same parent, different experience.
2. Efficiency Ratings (AFUE)
In Downey’s mild climate, super-high efficiency may not always bring a fast return on investment. That said, both brands offer ENERGY STAR®-rated furnaces that meet and exceed California’s Title 24 requirements.

- In Downey, even an 80–90% AFUE furnace may suffice for most homes since heating demand is relatively low.
3. Smart Thermostat & Tech Features
This is where Daikin has a clear edge.
