Duct Replacement in Culver City: Cost, Scope and How to Get It Quoted

You are weighing a duct replacement in Culver City, probably because a new system is going in or the old runs have failed a test. We replace and seal ducts as their own job or as part of an install. To get a price on your house, ask for the pressure test and written quote.

What a replacement costs

Replacing ductwork in a 1,200-square-foot bungalow with limited attic clearance can cost $3,500 to $8,300 before you even touch the air conditioning equipment. That is our figure for a bungalow job, and it is a range because the house sets the work.

A larger house, a two-story layout or a split between attic and crawlspace runs will price differently. We do not stretch the bungalow range to those. We test your ducts, measure the runs and write the number for your house before work begins. Nothing is ordered and nobody starts cutting until you have read it and said yes.

What moves the number

• Access. A roomy attic is faster than a tight one. Limited clearance is the main reason a bungalow lands higher in the range.
• Run length and count. More registers and longer trunks mean more material and more labor.
• Scope. Some jobs need only the leaking sections replaced. Others need whole trunks and branches.
• Sealing versus replacing. Where ducts can be sealed and pass the test, the quote reflects that instead.
• Equipment. If a new AC or furnace is going in the same visit, the duct work is coordinated with it.

What the quote lists

Our ductwork services quote is itemized so you can see where the money goes. Expect these lines.

• The pressure test result and which sections failed.
• Each section to be replaced, by run, with material named.
• Sections to be sealed instead, priced separately.
• Registers, boots and connections at the equipment.
• The mechanical permit and inspection, where the scope needs one.
• Cleanup and the final test.

Ask any company for the same breakdown. A single lump sum for the ducts makes it hard to tell a full replacement from a partial one, and the difference is the price.

How we decide replace or seal

We pressure test the ducts first. The test shows how much air leaks out of the system, and the quote follows the result. Sections that fail get replaced or sealed, and sections that pass stay. You see the finding before you approve anything.

Under Title 24 Part 6, California's Building Energy Efficiency Standard, duct work can require sealing and a leakage test, verified by a third-party HERS rater who is not the installer. Depending on the scope, we tell you whether your job triggers it.

Why do it with a new system

If a new AC or furnace is going into a house with failing ducts, the equipment is sized for air that never arrives. That is why we test before the equipment quote. Replacing the ducts during an AC installation saves a second visit, since the air handler and return are already open.

A heating installation works the same way. If the house heats through ducts, they are part of the job.

If you are a landlord with more than one unit, tell us how many systems share the building. Each set of ducts is tested and quoted on its own, so you can schedule the work unit by unit around your tenants.

From first call to finished ducts

• You send the address and a note on where the ducts run.
• A technician tests and measures the ducts on site.
• You get a written quote with the replaced sections itemized, before work starts.
• We file the permit with Culver City's building department when the work needs one, and book the inspection.
• The crew replaces the runs and seals the connections, and the system is tested at the end.

This applies to the Culver City area and the Westside neighborhoods around it, such as Mar Vista.

FAQ

Can you replace only part of the ducts?

Yes, if the test shows the rest passes. The quote names the sections that go and the sections that stay.

Does a duct replacement need a permit?

Replacing ductwork in California is permitted work. In Culver City the city's own building and safety division issues it, and we handle the filing and the inspection.

Can I do ducts and a new AC together?

Yes, and it often makes sense. One visit covers both, and the ducts are sized to the new equipment.

What if there is no room for ducts?

Then we price ductless mini split heads as an alternative. They skip the duct runs entirely, and the quote shows both paths.

Will the quote change after work starts?

The quote is written before any work starts, with each replaced section listed. If the scope changes, we talk to you first.
