Rerouting ductwork improves HVAC efficiency and adapts to home changes like remodels or additions. Here's a breakdown of costs, factors, and tips to help you plan.

1. Average Costs

• Basic Rerouting: $1,200–$6,000
• Per Linear Foot (Materials + Labor): $6–$23
• New Vent Installation: $250–$500 per vent

2. Duct Material Costs

| Material | Cost per Linear Foot | Features | |-------------------------|--------------------------|------------------------------------------------------------------------------| | Non-insulated Flex | $1–$3 | Affordable, easy to install, less durable | | Insulated Flex | $2–$4 | Better energy efficiency | | Fiberglass | $4–$6 | Resistant to noise and temperature changes | | Sheet Metal | $7–$13 | Durable, long-lasting, higher cost |

3. Cost Factors

• Length of Ducts: Longer duct systems increase costs due to material and labor requirements.
• Accessibility: Difficult-to-reach spaces like crawlspaces or attics can add labor costs.
• Return Air Drops: Replacing or adding a return air drop costs $300–$800.
• Ceiling/Drywall Repair: Post-project aesthetic fixes cost:
• Drywall Repair: $150–$330
• Ceiling Repair: $300–$1,200
• Mold or Asbestos Removal: Adds significant costs:
• Asbestos Testing/Removal: $250–$2,200
• Mold Remediation: $450–$6,000

4. Labor Costs

• Installation Fees: $5–$10 per linear foot
• Complex projects or limited access areas (e.g., small crawlspaces) can lead to higher rates.

5. Add-Ons to Consider

| Add-On | Cost |
|------------------------|-------------------------|
| HVAC Inspection | $70–$500 |
| Air Duct Cleaning | $150–$780 |
| Duct Insulation | $1–$6 per sq. ft. |
| Adding Vents | $250–$500 per vent |

6. DIY vs. Hiring a Pro

• DIY:
• Suitable for minor tasks like duct insulation or vent adjustments.
• Requires proper tools and HVAC knowledge.

• Risk of errors that may cause long-term inefficiencies.

• Hiring a Pro:

• Essential for complex rerouting or asbestos/mold issues.
• Ensures compliance with building codes and HVAC efficiency.

7. Ways to Save Money

• Compare Quotes: Get multiple estimates to find competitive pricing.
• Choose Affordable Materials: Opt for flexible or fiberglass ducts over expensive sheet metal.
• Bundle Services: Combine duct rerouting with other HVAC needs like cleaning or inspections.
• DIY Simple Tasks: Handle minor repairs or insulation to reduce labor costs.
• Avoid Peak Seasons: Schedule the project during off-peak times for better rates.

Summing it up

Rerouting ductwork can range from $1,200 to $6,000, depending on the materials, complexity, and additional repairs. Hiring a professional ensures a seamless, efficient installation while maximizing long-term HVAC savings. Proper planning, material choices, and strategic scheduling can help you stay within budget!
