When Custom Fabrication wins
Custom Fabrication tends to be the right call when upfront cost matters more than long-term operating cost, or when the existing infrastructure favors it.
When Pre-Fab Ductwork wins
Pre-Fab Ductwork typically wins on long-term efficiency, total cost of ownership, or environmental footprint — at the price of a higher up-front investment.
Side-by-side comparison
| Factor | Custom Fabrication | Pre-Fab Ductwork |
| --- | --- | --- |
| Up-front cost | Lower | Higher |
| Operating cost | Higher | Lower |
| Install complexity | Simpler | More involved |
| Lifespan | Standard | Comparable or longer |
Recommendation framework
Pick by horizon. If you're staying in the property less than 5 years, the cheaper option usually wins on net cost. If you're staying longer, run the math on operating costs.
