What that means for ducts
New-build ductwork
Roughly 68% of Prosper'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 Prosper
The part that changes from street to street.
Most of Prosper has gone up since 2010 and the houses are large, which moves the real question away from how dirty the ducts are and toward whether the system was ever balanced. A wide two-story plan in Windsong Ranch or Star Trail commonly runs two systems, sometimes three, with zone dampers in the attic and trunk lines long enough that the far bedroom is competing with the near one for air. None of that improves with cleaning. What a house this new can genuinely carry is construction leftover: gypsum dust that went in through open boots before the registers were set, a scrap of batt sitting at the first turn, occasionally a branch that was never connected to anything at all. Gas service is common here, so most of these homes have furnaces rather than heat pumps only. The honest part is that on a house this age the visit often ends without a cleaning. Verifying that two or three systems are clean and correctly connected takes longer than cleaning one would, and it can finish with nothing to show but a report.

03Plenum & Return-Box Cleaning — in this stock
Cleaning a system that is still carrying its own build.
A post-2010 system is usually not dirty in the way people picture. What comes out is the construction phase — drywall fines, sawdust, insulation fiber — that was pulled into open ducts before the house was ever occupied, plus whatever a kinked flex run has been collecting behind the crimp. That is a different cleaning: shorter, more targeted, and far more dependent on the before-and-after photographs, because the difference is not something you can smell.
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 Prosper, answered straight.

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.
Downstairs runs cold and upstairs never keeps up. Is that a duct problem?
It is a duct and damper problem far more often than a dirt problem. Prosper's larger plans use zoning to serve very different loads off one trunk, and a zone damper stuck part open makes an entire floor feel wrong. Cleaning does not move air. We read the registers first, and if the fix is a damper or a bypass setting we say that instead of quoting a cleaning.
The house is three years old. Is there any reason to look inside the ducts?
One reason: what the trades left. Boots stay open through drywall and paint on nearly every build, and anything heavy settles at the plenum and the first turns. That is where we scope. If it is clean, a house this age should be left alone for several years, and we will put that in the report so the next company that knocks has something to argue with.
We honestly do not know which system serves which rooms.
Neither do most people in these plans, and it matters the moment somebody quotes you. On a two or three system house we tag the equipment, trace what each unit feeds and hand you a simple map with the report. Beyond keeping the quote honest, it tells you which filter to change on what schedule, which is not the same for a system serving bedrooms and one serving rooms nobody uses on a weekday.
