Targeted source removal for the runs that actually need it.

What that means for ducts
Mixed-era stock
Schertz splits across build eras — 9% pre-1980, 27% 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 Schertz
The part that changes from street to street.
Schertz is unusual in two ways that matter for ductwork. Almost every home is detached single-family, with very little attached or stacked housing anywhere in the city, and almost every one of them heats with electricity rather than gas. That means no flue, no heat exchanger, and one cabinet doing all the work: blower, evaporator coil, filter rack and strip heaters in a single box that is where nearly every real air-quality issue in this city begins. It also explains the burning smell people report on the first cold morning, which is dust scorching on the heat strips rather than a failure. The other local factor is turnover. With Randolph and the wider joint base next door, houses here change hands and tenants often, and a system inherits whatever the last household did to it. We find that history in the cabinet before quoting anything.

03Supply & Return Duct Cleaning — in this stock
Cleaning where the street does not tell you the answer.
This is the stock where two houses forty feet apart genuinely need different work — one built when ducts were retrofitted, one built when they were designed in. Quoting a cleaning from an address here is guessing. It is the single strongest case for putting a camera in first and letting the footage decide whether you are buying a full system or two runs.
How do you know cleaning part of the system is enough?
The camera decides, not a hunch. We scope the whole system first; if debris is concentrated in the returns or specific branches, we clean those and document the rest as verified clean.
Why are return ducts dirtier than supply ducts?
Because they run upstream of the filter. Returns pull raw room air — dust, pet hair, fibers, pollen tracked in on shoes — straight into the ductwork before anything filters it.

05Questions
Asked in Schertz, answered straight.
How do you know cleaning part of the system is enough?
The camera decides, not a hunch. We scope the whole system first; if debris is concentrated in the returns or specific branches, we clean those and document the rest as verified clean. If footage shows buildup everywhere, we'll say a full cleaning is the honest recommendation — with the photos to prove it.
Why are return ducts dirtier than supply ducts?
Because they run upstream of the filter. Returns pull raw room air — dust, pet hair, fibers, pollen tracked in on shoes — straight into the ductwork before anything filters it. Supplies only see air the filter has already scrubbed. That asymmetry is why return-side cleaning is often the smartest partial job.
We're a military family renting near Randolph. What can we reasonably ask for?
A fair question and a common one here. Ask the owner for the filter size and a change schedule in writing, and report sweating vents or a whistling return promptly. Documented airflow complaints get repairs approved far more often than a general request for duct cleaning ever does.
First cold morning of the year, the house smells like burning. Is that dangerous?
Usually it is dust on electric heat strips, which nearly every Schertz home has instead of a gas furnace, and it burns off within minutes. If the smell lasts, repeats on later runs, or comes with tripping breakers, stop using heat and have the air handler inspected before anything else.
There's no furnace in our attic, just one cabinet. What actually gets inspected?
In an all-electric Schertz home that cabinet is the air handler: blower, evaporator coil, heat strips and filter rack in one box. It is also where nearly every genuine air-quality problem starts. We open it, photograph the coil and check the condensate drain before discussing the duct at all.
