Frequently Asked Questions
How much does air duct replacement cost?
The price depends on your home size, duct layout, and location. Most homeowners pay between $1,500 and $7,000 for a full replacement.
How much does it cost to replace air ducts in a home?
The cost changes with square footage. Plus the type of duct material, number of vents, and labor. The best way is to get quotes from licensed HVAC pros and compare.
How much does it cost to replace ductwork in an average house?
It can range widely. Factors include attic access, design, and system size. An expert inspection gives the most accurate estimate.
What is the cost to replace ductwork compared to repairs?
Repairs like sealing and insulation are cheaper at first. But full replacement is needed when ducts are too old or damaged.
Is AC duct replacement worth it?
Yes. If your ducts are leaking or causing poor air quality. New ducts improve comfort, lower bills and even prolong the life of your AC.
What does the duct 2-foot rule mean?
It means there should be at least two feet of space between duct fittings. This spacing helps airflow move smoothly. Also keeps energy costs lower.
Does homeowners insurance pay for duct replacement?
Usually, no, because ducts are seen as maintenance. But if damage is caused by a covered event, like fire or vandalism, insurance helps.
Should ductwork be replaced after 20 years?
Yes. After 20 years, ducts leak and lose efficiency. Replacing them keeps your system performing well. It also saves energy.
How long does replacing ductwork take?
It takes from a few days to a week. Timing depends on the size of your home. Also, on how complex the system is.
What costs more—metal duct or flex duct?
Metal ducts cost more to buy and install. But they last longer and have lower energy waste over time. Flex ducts are cheaper but less durable.
Can I replace my own ductwork?
You can. But it’s not advised. Ductwork replacement needs skill and special tools. A mistake can hurt airflow and waste energy.
Does new ductwork increase home value?
Yes. Buyers like energy-efficient systems and cleaner indoor air. Replacing old ducts can make your home more appealing.
How do I know when to replace my ductwork?
Look for uneven heating or cooling, higher bills, dust buildup, or musty smells. An HVAC technician confirms if replacement is needed.
How much does it cost to add a vent to my system?
Adding a vent costs $250 to $500. Price depends on labor and how hard it is to reach the duct.
