Can I Hire an HVAC Technician for Ductwork Projects?

While ductwork contractors focus primarily on ducts, HVAC technicians handle the entire heating, ventilation, and air conditioning system. They understand how duct layout and sealing interact with equipment, which helps improve overall performance and efficiency. They also diagnose airflow issues or inefficiencies caused by faulty components.

Choose a ductwork contractor for duct design, installation, or duct-specific repairs. Choose an HVAC technician when you want broader system assessment and optimization. Confirm experience with your duct type.

How Do Ductwork Contractors Work On Ductwork?

Here is how pros plan, install or replace, and verify ductwork for reliable performance:

  1. Planning and assessment: Discuss your HVAC goals, home layout, and comfort needs. The contractor calculates duct size and layout, reviews vent placement, and evaluates insulation and ventilation requirements.

  2. Installation or replacement: The contractor cuts and assembles duct sections, then seals every joint and connection to prevent air leaks. They use specialized tools and materials to connect and insulate securely.

  3. Testing and wrap-up: After installation, they test the system for proper operation and code compliance, check for leaks, measure airflow, and share maintenance tips to keep everything running smoothly.

How Much Does Ductwork Installation Cost?

Ductwork installation averages $1,250, with homeowners paying between $450 and $2,200 on average. Labor represents 60% of project costs, with pros charging between $50 and $110 per hour. Total costs depend on the size of your ductwork system, accessibility, insulation, and other factors.
