Ductwork repair & replacement in San Diego County
Half the "my AC is too weak" calls in inland San Diego's 1970s–80s tract homes aren't the AC at all — they're original ducts leaking cooled air into the attic. We test airflow instead of guessing, then seal, repair, or replace what's actually wrong.
Signs your ducts are the problem
- Two rooms are always hot while the rest of the house is fine
- Vents whisper when they should blow
- Dust builds up fast no matter how often you clean
- The system is newer but the comfort never improved
- Your attic ducts are original to a 40-year-old house
- Sky-high bills with mediocre cooling — you're conditioning the attic
What we do
We measure airflow at the registers, inspect the attic run by run, and show you photos of what we find — crushed flex, disconnected boots, leaky plenums, insulation that gave up in the Reagan years. Then we fix what needs fixing: reattach and seal, replace bad runs, or re-duct the house. Replacements meet the state's ≤5% leakage standard, verified by an independent HERS test.
What things actually cost
| Job | San Diego market range |
|---|---|
| Duct repairs & sealing | varies with scope |
| Ductwork replacement (San Diego market) | $1,000 – $6,000 |
These are the ranges San Diego homeowners actually pay across the market — not a quote. We price your exact job before any work starts, and the number doesn't move after.
The honest order of operations
If a company quotes you a bigger AC for a hot-room problem without ever going in the attic, get a second opinion. Fixing airflow first is cheaper — and sometimes it makes the "too small" AC suddenly adequate. One of our favorite reviews is from a customer two other companies couldn't help; the fix was the ducts.
“We called out two other companies who could seem to fix the problem. [...] Mr. John came right in and checked our unit and found the problem right away he fixed the entire air flow problem [...] He is very nice and works hard to ensure he finds the problems and will fix it.”
