What that means for ducts
Mixed-era stock
Tomball splits across build eras — 18% pre-1980, 16% 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 Tomball
The part that changes from street to street.
For a town this size Tomball carries an unusual amount of attached housing, and duplexes, townhome rows and senior buildings do not behave like detached houses. Each unit normally has its own small system, but the attic above a row is one continuous space cut up by draft stops that seldom seal well, so a leaking return plenum in your unit is drawing on air the whole building shares. The footprint is small, the duct is short, and the useful work is almost never a cleaning. It is filter fit and getting the return sealed to the cabinet. The detached half of town divides by age. Around the old depot the houses predate 1980 and had central air added to them, and out north and west the 2000s subdivisions brought attic flex and plenty of it. Gas and electric are close to evenly matched here, which means there is no safe assumption about what is in your closet, and a furnace brings a combustion cabinet into a visit that would otherwise be about airflow.

03Plenum & Return-Box 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.
What if the plenum liner is in bad shape?
We stop and show you rather than bill for a cleaning that can't help. Degraded or moldy duct-board liner can't be restored by cleaning — EPA guidance is clear that porous materials in that condition need replacement, which is HVAC-contractor work.
Can you clean just the plenums without doing the whole system?
Yes — that's precisely what this service is. The plenums are the highest-traffic surfaces in the system, so cleaning them alone delivers outsized value on older systems, from $199.

Asked in Tomball, answered straight.
What if the plenum liner is in bad shape?
We stop and show you rather than bill for a cleaning that can't help. Degraded or moldy duct-board liner can't be restored by cleaning — EPA guidance is clear that porous materials in that condition need replacement, which is HVAC-contractor work. Our photos give you exactly what that conversation needs.
Can you clean just the plenums without doing the whole system?
Yes — that's precisely what this service is. The plenums are the highest-traffic surfaces in the system, so cleaning them alone delivers outsized value on older systems, from $199. If the camera later shows the runs need work too, that's a separate, honest conversation with evidence attached.
We own half a duplex. Does the neighbor's system affect our air?
Not through the duct, which is separate. Through the attic, sometimes. The draft stop between units is often incomplete, and if either unit has a leaking return plenum up there, both are pulling on the same shared attic air. That is why we scope the return side first in attached housing. Two units done on the same day also costs less than two separate visits.
My mother is in one of the senior buildings and says the air bothers her.
Worth investigating, with one caveat we give up front: no cleaning company can promise a health outcome, and the evidence has never supported routine cleaning as a way to prevent illness. What we can do is check whether the filter actually seals in its rack, whether the return is drawing from the corridor, and what the coil and pan look like. Those are the things that change what she breathes.
Our place by the depot is from the 1960s. Is it a different job?
A different starting point. Central air was added to those houses decades after they were framed, so the trunk went wherever there was room and the return is usually one undersized grille. We take a static pressure reading first, because on a small retrofit system a poor number normally means a crushed or disconnected run rather than accumulation, and those two lead to very different work.
