Air Duct Replacement Cost Factors 

Air duct replacement costs in Houston, TX, depend on several different factors, such as the type of ductwork and the size of your house. Consider these cost factors when budgeting for air duct replacement.

Size

The size of your home directly affects air duct replacement costs. Larger homes require more materials and labor to replace the entire duct system. On average, the cost ranges from $2,000 to $5,000 for a small- to medium-sized home. However, duct replacement can run as low as $1,400 for smaller homes and as high as $9,000 for larger homes. Here’s how the size of your home affects duct replacement costs:

Home Size (Sq. Ft.)Cost
1,000–2,000$813–$2,959
2,000–3,000$2,959–$5,000
3,000–4,000$5,000–$9,000
4,000+$9,000+

Duct Location

If only specific sections of your ductwork need replacement, such as in a renovation project, costs will depend on the location of the damaged or worn ductwork. Replacing ducts in hard-to-reach or concealed areas—like attics, basements, ceilings, walls, or crawl spaces—can increase labor costs. Here’s how the location of the ducts could affect their cost:

Duct LocationCost
Exposed$813–$2,959
Wall or ceiling$1,000–$4,000
Basement$1,852–$3,100
Attic$2,200–$5,600
Crawl space$2,959–$7,300

Duct Material

4 ductwork types compared visually, including metal sheet, flex, fiberglass, and fiberboard

The material you choose for your replacement ducts affects both their cost and longevity. The most commonly used duct material in Houston, TX, is metal sheeting.

Sheet metal ducts are durable but pricey. Flexible ducts, on the other hand, are more affordable but may need to be repaired or replaced sooner. Here’s a breakdown of air duct replacement costs based on duct material: 

Duct TypeCost per Linear Foot
Flex (non-insulated)$1–$3
Flex (insulated)$2–$4
Fiberglass$4–$6
Fiberboard$4–$6
Metal sheet$7–$13

HVAC Pro Costs

Labor accounts for about 60% of the total cost to replace air ducts, meaning that for the average cost of air duct replacement in Houston of $1,852, labor would make up $1,112 of the total. For hourly rates, expect to spend $50 to $110 per hour, with air duct replacement taking five to seven hours.

Your pro will also need to apply for a permit from the City of Houston, and they will build the cost of permits into the project total. Permit costs vary by project type and value, with most Houston building permits costing 1% of the project total.

Always leave air duct replacement to a local HVAC pro in Houston, TX. Attempting to handle ductwork yourself can lead to air leaks and costly energy bills, not to mention DIYing could void your homeowner’s insurance policy coverage and any HVAC part warranties. A pro can quickly and safely replace your ducts and have your HVAC working efficiently again.

Pro Tip

Quality ductwork will increase the efficiency of your HVAC, sometimes by 20% to 30%. This is because there is reduced air leakage due to better insulation and more optimized airflow. This means your HVAC doesn't have to work as hard to keep the desired temperature, so it uses less energy.

Does Air Duct Replacement Increase Home Value?

Air duct replacement has a very small effect on your home’s value. However, updated ducts are much more attractive to potential buyers than old, dirty ductwork that will need to be cleaned or replaced soon. 

By replacing old, inefficient air ducts, you’ll also benefit from an HVAC system that can work more efficiently, leading to lower energy bills each month.
