Duct Cleaning & Repair in Jacksonville, FL — AC All Stars Jax
Your ductwork is half your AC system, and it's the half nobody looks at. In Jacksonville, ducts run through attics that hit 130°F all summer — and when they leak, tear, or sweat, you pay to cool the attic while your bedrooms stay warm.
Duct leakage is one of the most common problems we find in Northeast Florida homes. Typical houses lose 20–30% of their conditioned air through leaky ducts. That's money out of your pocket every month, plus humidity pulled into the system from the attic.
We inspect, seal, repair, and replace ductwork: crushed flex duct, disconnected runs, torn insulation, sweating trunks, and the flimsy builder-grade installs that were never sized right in the first place. If a room has never cooled properly, the duct serving it is the first suspect.
On the cleaning side, we're honest about it: duct cleaning helps when ducts have real contamination — construction debris, rodent activity, visible mold or dust buildup. It's not a magic cure-all, and we'll tell you if your ducts don't need it. What matters more in most homes is sealing the leaks.
Every job ends with airflow verified at the registers. You should feel the difference in the rooms that used to lag behind.

Frequently Asked Questions
Do I actually need duct cleaning?
Maybe not — and we'll tell you straight. Cleaning makes sense with visible contamination, rodent issues, or post-construction debris. If your real problem is leakage, sealing is the better spend.
Why is one room always hot?
Usually a crushed, kinked, disconnected, or undersized duct serving that room. Occasionally it's a return-air problem. An inspection finds it fast.
How much air do leaky ducts really lose?
Studies and our own measurements put typical Florida homes at 20–30% loss. Sealing that is one of the highest-return fixes in HVAC.
