What that means for ducts
Mixed-era stock
Friendswood splits across build eras — 7% pre-1980, 13% since 2010 — so two houses on the same street can need completely different work. It is the case where guessing from the curb is worst, and where a camera before a quote saves the most money.
That is a reading of the city’s stock, not a diagnosis of your home. Which of it applies to you is exactly what the camera settles — and why we would rather run one than quote from a postcode.
02Working in Friendswood
The part that changes from street to street.
Friendswood runs on natural gas more heavily than most of the bay-side suburbs, so the typical house here has a real furnace with a burner compartment and a flue rather than an air handler and heat strips, and skipping the cabinet leaves half the system uninspected. The other thing shaping this city is that many of these houses have been rebuilt from the floor up while the ductwork stayed exactly where it was. Clear Creek has been inside homes here more than once, and the repairs that followed replaced walls, flooring and cabinets without anyone going into the attic. In several of those rebuilds the system ran during demolition and sanding, which pulls gypsum dust past whatever filter happened to be in the rack and spreads it through the supply side. So the duct is frequently the oldest surviving component in a house that looks brand new inside. Most of the stock dates from the 1980s through the 2000s, old enough for the flex to matter and new enough that owners assume it was done right.

04Questions
Asked in Friendswood, answered straight.
We were gutted and rebuilt after a flood. The ducts looked fine from the attic hatch.
There are two separate questions in that. Was anything submerged, because soaked flex insulation and duct board cannot be restored by cleaning and need replacing. And did the system run while the house was being cut apart, because that is how fine gypsum dust ends up coating the inside of every supply run. A camera pass answers both in one visit.
The house feels clammy in August even with the AC running constantly.
That is usually not a duct problem, and we would rather say so before quoting. Equipment sized generously for a Gulf Coast summer satisfies the thermostat quickly, shuts off, and never runs long enough to pull moisture out of the air. Measure the indoor humidity first. If it sits high while the temperature is fine, cleaning the ducts will change nothing about how the house feels.
There is a musty smell for the first minute after the system starts.
Startup odor points at the coil and drain pan far more often than at the duct, because that is the only part of the system that stays wet. In a house that has flooded we also check whether the smell is coming from a wall cavity near a supply boot rather than from inside the run. If it is not ours, we will tell you where to look next.
