If you typed air duct repair near me because the AC runs all afternoon and a Culver City living room still will not cool, the ducts are the first thing to put on a test. Culver HVAC Repair pressure-tests the duct system, shows you where the air is escaping and writes the repair price before anyone touches a joint. Ask for the duct test and your written quote.
What the duct test finds
Old galvanized ducts separate at the joints. When they do, cold air ends up in the crawlspace or the attic instead of in your rooms. The only way to see it is to pressurize the system and trace the leaks.
That is the visit. We pressure-test the runs, find each failed joint or section, and tell you what we found in plain words. You see the result before you decide anything. Our ductwork service covers the whole job from the test to the finished repair.
The fix comes in two forms:
- Sealing the leaking joints, including Aeroseal duct sealing where it suits the run.
- Replacing the sections that have failed past sealing.
When both apply, both go in the quote, so you choose with the numbers in front of you.
What sets the price of an air duct repair
The number comes from the visit, and it is written before work starts. A few things move it:
- How many joints and sections failed the test.
- Whether the run can be sealed or has to be replaced.
- How hard the run is to reach in your crawlspace or attic.
- Whether you want insulation upgraded or airflow balanced while the ducts are open.
Sealing a joint is a smaller job than replacing a section, and a whole failed run is a bigger one than either. We will not guess at that from the phone. Send us the room that stays warm and we will book the test.
Test the ducts before you buy a compressor
A system that runs and does not cool can look like a dead compressor. Sealing a leaking duct can solve what looks like a $1,300-$3,300 compressor problem, which is why we test the ducts before anyone blames the equipment.
If the test shows the ducts are sound, we move on to the equipment and say so. That is an AC repair call, and it gets the same written estimate before any part changes. If the system itself is beyond repair, the replacement is laid out beside the repair so you can compare.
How the duct job runs once you say yes
You call, we ask what the system is doing and which rooms fall behind, and we give you an arrival window on that same call. The technician tests the ducts, shows you the leaks and hands you the written price. Nothing starts until you approve it.
On the repair day, the failed joints are sealed or the failed sections are replaced, as the quote says. If you added insulation or airflow balancing, that is done in the same visit. You get a before-and-after efficiency report, so the result is on paper and not only in how the rooms feel.
Permit and code questions on duct work
Duct work in California is permitted work. In Culver City, the permit comes from the city's own building and safety division, not from the City of Los Angeles. Depending on the scope, Title 24 can require duct sealing and a duct leakage test verified by a third-party HERS rater who is not the installer.
If your job reaches that point, we tell you at the quote stage, not after the ducts are open. We handle the paperwork for the work we do.

Duct repair questions
Do I need to be home for the pressure test?
Someone should be there to let us in and to see the result. We show you where the leaks are while we are there, so you can ask about each one.
Can you repair part of the ducts and leave the rest?
Yes. The quote lists each section separately. You can approve the failed ones now and leave sound runs alone.
What if the ducts test fine and the house still will not cool?
Then the fault is in the equipment, and we say so. We move to the AC itself, test the capacitor, contactor, fan motor and refrigerant charge, and write that repair price too.
Will the price change after you open the ducts?
The quote is written from the test, before work starts. If we find something the test could not show, we stop and give you a new written price. Nothing proceeds without your approval.
Is a gas smell a duct problem?
No. If you smell gas, leave the house first and call SoCalGas or 911 from outside.
