What that means for ducts
New-build ductwork
Roughly 38% of McKinney's homes were built since 2010. New does not mean clean: the commonest thing we pull out of a five-year-old system is the construction phase itself — drywall fines, sawdust, insulation fiber — plus builder-grade flex that was kinked or crushed on the day and has been throttling that run ever since. Photographs matter more here, not less.
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 McKinney
The part that changes from street to street.
McKinney is two housing markets a few miles apart, and confusing them leads to bad advice. Around the historic square, houses from the turn of the last century were ducted generations after they were built, threaded through balloon-framed walls and tight attics wherever a chase could be found. The findings there are usually mechanical, a run that came apart above a ceiling or a return far too small for a modern blower, rather than a dust problem. North and west of that core sits a very large post-2000 ring where systems are clean from use and carry only what the builders left behind. Underneath both is blackland prairie clay, which swells and shrinks through the year and slowly works boot connections loose where duct meets floor or ceiling. Those gaps let attic and crawl air into your supply, and sealing them is cheaper, and does more for the air you breathe, than a cleaning.

03Duct Sanitizing & Antimicrobial Treatment — in this stock
Treatment in new stock — usually the wrong purchase.
In a house built since 2010 there is rarely a documented indication for an antimicrobial or a UV lamp, and we will normally say so. Where a UV light does earn its place here it is a coil-hygiene decision on a system that runs long humid cycles, not an air-purity claim. If someone has quoted you a treatment on a five-year-old system without showing you a reason on camera, ask what the reason was.
Is the antimicrobial treatment safe for my family and pets?
We only use products EPA-registered specifically for use in HVAC systems, applied exactly as the label directs — including any re-entry and ventilation instructions, which we walk you through before we start. You also get the product name and label documentation for your records.
Why won't you sanitize without cleaning first?
Because fogging product over a layer of dust treats the dust, not the duct surface — the buildup simply shields what's underneath. It wastes your money and violates the spirit of the label.

05Questions
Asked in McKinney, answered straight.
Is the antimicrobial treatment safe for my family and pets?
We only use products EPA-registered specifically for use in HVAC systems, applied exactly as the label directs — including any re-entry and ventilation instructions, which we walk you through before we start. You also get the product name and label documentation for your records. No off-label products, no improvised mixes, ever.
Why won't you sanitize without cleaning first?
Because fogging product over a layer of dust treats the dust, not the duct surface — the buildup simply shields what's underneath. It wastes your money and violates the spirit of the label. Source removal first, then treatment where there's a documented indication. Any company that offers it the other way around is selling theater.
We bought an old house near the downtown square. Do different rules apply?
Completely different from the newer parts of McKinney. Century-old houses were ducted generations later, through balloon-framed walls and tight attics with almost no room to work. We map the routing before quoting, because disconnected runs and badly undersized returns are far more common findings than genuinely dirty duct.
Our house is in a 2010s subdivision on the north side. Is it the same visit?
No. There the question is construction leftovers rather than accumulation. Drywall dust and cut-off scraps sitting in a boot are a one-time cleanup, not a recurring service. We inspect, show you what is in there, and if the builder sealed the system properly during the build there is nothing to do.
Does the blackland prairie soil under McKinney affect ductwork?
Indirectly, and it is worth knowing. Expansive clay under these slabs moves seasonally, and that movement works joints loose where boots meet floors and ceilings. A separated boot quietly pulls attic or crawl air into your supply. Sealing those is cheaper and more effective than cleaning the branches they feed.
