Typical Cost Ranges
Air duct replacement expenses vary depending on a home’s size, the materials selected, and the overall complexity of the project. In Los Angeles, additional factors such as permit requirements and local labor costs significantly influence the final total. Homeowners benefit from access to highly skilled HVAC professionals like Air Plus HVAC, Inc., who deliver efficient, precise, and long-lasting results tailored to each home.

Key Cost Drivers
Home Size & Duct Length
The size and square footage of your home directly impact how much ductwork is needed. Larger homes require more materials and labor, while smaller spaces may allow for more straightforward layouts. Air Plus HVAC conducts detailed assessments to design duct systems that optimize airflow and energy efficiency.
Accessibility
If your existing ductwork is located in tight crawl spaces, attics, or behind finished walls, replacement becomes more labor-intensive. These challenging spaces require more time, effort, and precision. Using advanced tools and minimally invasive techniques, Air Plus HVAC ensures high-quality work with minimal disruption to your home.
Material Type
Duct materials vary in cost, durability, and performance. Options include:
- Flexible Ducts: Easy to install and adaptable to tight spaces.
- Fiberglass Ducts: Provide built-in insulation for energy savings.
- Sheet Metal Ducts: Offer the greatest strength and long-term durability.
Air Plus HVAC helps you select the best fit for your comfort goals, efficiency needs, and budget.
Labor & Expertise
Duct replacement requires more than simple removal and installation. Proper sealing, airflow balancing, and system design are essential for performance and efficiency. Air Plus HVAC’s trained professionals deliver craftsmanship backed by engineering knowledge—ensuring your system operates at its full potential.
Insulation Quality
Upgrading or adding insulation during duct replacement can dramatically improve energy efficiency. Quality insulation reduces heat loss and prevents air leaks, helping you maintain steady indoor temperatures and cut down on monthly energy bills.
Contaminant Concerns
Mold, asbestos, and heavy dust accumulation must be addressed before duct replacement. Air Plus HVAC identifies these issues early and recommends safe, professional remediation to protect your indoor air quality and your family’s health.
Drywall or Ceiling Modifications
When ducts are concealed behind walls or ceilings, portions of drywall may need to be removed and restored. Air Plus HVAC approaches these situations carefully, using clean, efficient methods to access hidden ductwork and ensure your home is professionally restored afterward.
Permits & Code Compliance
In Los Angeles, duct replacement often involves city permits and inspections. Navigating these requirements can be complex. Air Plus HVAC takes care of the entire process—securing permits, meeting local codes, and coordinating inspections to ensure your project meets all compliance standards.
Additional Vents & Layout Changes
Optimizing vent placement can greatly improve airflow and comfort. Whether you’re adding new vents or repositioning existing ones, Air Plus HVAC customizes layout changes to eliminate hot and cold spots, improve air circulation, and enhance overall comfort.
Zoning System Upgrades
Zoning divides your home into different climate-controlled areas, allowing personalized comfort and increased efficiency. If you’re looking to improve control and reduce energy waste, Air Plus HVAC can design and install a zoning system tailored to your home’s layout.
Los Angeles-Specific Considerations
Homes in Los Angeles range from historic bungalows with aging ductwork to new builds with modern efficiency expectations. Add to that the city’s hot climate and stringent building codes, and it becomes clear why expert local knowledge matters. Air Plus HVAC understands the region’s requirements and challenges, from navigating permit timelines to designing duct systems that handle summer heat and multi-story airflow dynamics. Their team brings a deep understanding of local construction styles, insulation needs, and compliance mandates to every project.
Estimated Scenario for Los Angeles Homes
The scope and cost of duct replacement projects vary significantly based on the home’s size, layout complexity, and choice of materials. Additional upgrades such as new insulation, zoning, or air purification can also extend the timeline and budget. Permitting and any required remediation (e.g., mold or asbestos removal) may add further considerations. A comprehensive home evaluation from Air Plus HVAC is the best way to determine a customized plan that fits your needs and ensures long-term value.
