- Warranties and support: A transferable warranty and U.S. manufacturing can be valuable for future home ownership and serviceability.
- Installation approach: Some kits are DIY-friendly with complete instructions; others may require professional installation, especially longer runs.
- Code compliance: Confirm local codes require listed liners and proper clearance from combustibles in your area.
