What that means for ducts
Retrofit-era ductwork
About 35% of Farmers Branch's homes went up before 1980, which is before central air was designed into a house rather than added to it. Duct runs in that stock were threaded through attics and crawl spaces after the fact, often more than once, and the flex in them has had decades of Texas attic heat. Expect route surprises, expect joints that have worked loose, and expect a system nobody has opened.
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 Farmers Branch
The part that changes from street to street.
Farmers Branch has almost exactly as much housing built before 1980 as it does housing built in the last dozen years, and the two halves have very little in common. The older half is the 1950s and 60s slab stock around Brookhaven and Webb Chapel, where central air was added to houses designed without it. In some of those we still find floor registers fed by supply runs cast below the slab rather than routed overhead, and that is not attic flex and cannot be treated like it. If a below-slab run has taken on moisture, the honest recommendation is to abandon it and go overhead, which is HVAC contractor work, not a cleaning. The newer half of the city is Mercer Crossing, where most units are attached, the equipment is a closet air handler and the entire system can be scoped in one pass. Electric heat is the majority on both sides of that divide, so the coil rather than a burner is where we start.

03Duct Sealing (Aerosol) — in this stock
Leakage in retrofitted runs.
Duct leakage is worst where the ductwork was added later, and in stock this age it is common to find a system losing a meaningful share of its conditioned air into an attic. That shows up on a summer bill long before anyone thinks about ducts. Sealing here is often the higher-value purchase than cleaning — and unlike a cleaning, it has a before-and-after number attached to it.

05Questions
Asked in Farmers Branch, answered straight.
Our 1958 house has vents in the floor. What does that tell you?
That the supply side may run below the slab, which changes the whole conversation. Those runs sit in ground contact, and once moisture or soil gets in there is no cleaning that makes them right again. We camera them before saying anything. When the finding is bad we say so plainly, because the correct answer is a new overhead system, not our brush.
We just moved into an apartment at Mercer Crossing. Should we clean the ducts?
Not on a schedule. In a new attached unit the duct is short, the system is young and the useful check is whether the filter fits its frame and whether the return closet is sealed against the chase behind it. Save the money for a better filter, and call us if something actually appears at the registers.
The old part of the house has one return in the hallway and it roars.
A single central return sized for the original equipment is typical in this stock, and every replacement since has moved more air through the same opening. That is what you hear. It also means the system draws harder on every gap it can find. Adding return area does more for comfort and for filtration than cleaning the supply branches would.
