Buying Guide
- What width do I need? If your lines use 3″ components, choose 3″ width; 4″ options are for wider line sets. Ensure the kit includes the necessary straight ducts, elbows, and wall covers for your layout.
- Is length important? Longer runs need more ducting and longer wall exposure protection. Pick a kit that accommodates your total line length plus any extra for future expansion.
- Material considerations: PVC and PP are common. PVC is sturdy and weather-resistant; PP tends to be lighter and paintable. Choose based on climate and finish needs.
- Easy installation: Look for kits with snap-on designs or complete hardware. Some sets allow parts to be separated for easier mounting on existing structures.
- Finish and color: If exterior aesthetics matter, select a paintable or neutral gray option that blends with your home’s siding or brick.
