What that means for ducts
Mixed-era stock
Lewisville splits across build eras — 6% pre-1980, 21% 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. Under half the units here are single-family, so a fair number of systems are shared or stacked, and access is the first thing we check.
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 Lewisville
The part that changes from street to street.
Most of Lewisville was built after 2000 and a great deal of it is rented. Between the apartment corridors along I-35E and Vista Ridge and the townhome and condominium stock nearer the lake, fewer of the addresses here are detached houses than in almost any city around it, and the systems behind those addresses are young. That turns our answer to not yet more often than to yes. What we do find, over and over, is a filter problem rather than a dirt problem. This era of construction favors the filter-back return, a hinged grille in a hallway ceiling or wall with a one-inch slot behind it, and a one-inch filter is a compromise before anyone touches it. Someone reads that a higher rating is better, buys the densest one on the shelf, and the blower spends the summer pulling against it. Airflow drops, the coil runs colder than it should, and the house feels humid while the thermostat insists everything is fine. The right filter for your blower is not the highest number on the shelf, and that is worth saying plainly.

04Questions
Asked in Lewisville, answered straight.
We bought the best filter they sell and the house feels worse. How?
Because rating and airflow trade against each other. A dense one-inch filter in the shallow return slot these Lewisville buildings use adds resistance the blower was never sized for. Air slows, the coil gets too cold, dehumidification suffers and the house feels clammy. Either step the rating back or move to a deeper media cabinet that filters finely without choking the system.
Our building is fifteen years old. Do the ducts need cleaning yet?
Usually not for accumulation. In a unit that age with a maintained filter there is rarely enough in the runs to justify the work, and there is not much run to begin with. We scope it and show you. Where we do find something worth doing in these buildings it is normally at the coil and the drain pan rather than in the duct.
Who is responsible in a rented townhome?
The owner, for anything past the grille, and that is worth establishing before you spend anything. A large share of these units in Lewisville are owned by someone who does not live in them. A written inspection with photographs is the thing that gets an owner to act, and it costs a fraction of what a cleaning does.
