Air Duct Cleaning in Southchase, FL

Frequently Asked Questions

My house is from the early '90s and the ducts have never been touched. Is cleaning even safe on flex that old?

Usually yes, but it has to be inspected first. Southchase homes were built with flex duct throughout, and after 25 to 35 years the outer jackets get brittle and crack, especially the runs that sit in direct attic heat. We look at the condition of the jacket and inner liner before anything spins. If a run is already split or the inner liner has pulled loose at the collar, cleaning it won't fix anything. That section needs repair or replacement, and we'll tell you that instead of agitating a duct that can't take it. Sound flex cleans fine with soft brushing and negative air.

Why does my house get dusty again so fast after a cleaning?

Two things happen together around here. The lots are flat with sandy ground, so fine sand tracks in and gets kicked up constantly, and it's light enough to stay airborne and get pulled into returns. The bigger factor is usually leakage: on duct this age, boots pull loose from ceiling drywall and the mastic or tape at the collars has dried out, so the system draws unfiltered attic air straight into the supply side. Clean ducts that are still pulling from the attic will load back up. Sealing the boots and collars is what changes the dust level.

What do you find wrong most often in Southchase houses?

Sagging runs between the trusses is the most common one. Builder-grade straps were spaced wide and the flex has settled over decades, so you get low spots that trap debris and cut airflow to the far rooms. Right behind that is strap crush, a tight strap pinching a run down to a fraction of its diameter. We also see a lot of original boot and register hardware with rusted screws and warped register frames that no longer seat flat against the ceiling. None of that shows up from inside the house. It shows up when someone's in the attic looking at the runs.

We get standing water in the yard after the summer storms. Does that affect the ducts?

It affects the attic more than the ducts directly. Water sitting on these flat lots keeps the ground saturated and humidity high, and that moisture works its way into the attic space where most of your duct run lives. Humid attic air around cool supply duct means condensation on the jacket, and where a jacket is already cracked that moisture gets into the insulation. If you're seeing damp spots at ceiling registers or smelling something musty when the system kicks on after a storm week, that's worth looking at sooner rather than later.
