Plenum & Return-Box Cleaning in The Colony
Deep cleaning of the distribution boxes at your air handler.
01The Colony — the housing record

What that means for ducts
Mixed-era stock
The Colony splits across build eras — 4% 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 The Colony
The part that changes from street to street.
Almost nobody in The Colony heats with gas. This is an electric city, which means heat pumps with resistance strips as backup, and that changes both what we inspect and what we get called about. Every year in the first week of real cold we take calls about a hot metallic burning smell coming out of the vents, and in a house like this it is almost never the duct. It is dust burning off the resistance elements the first time they energize after nine idle months, and it clears within a few cycles. What is worth checking in these houses is the coil and the drain pan, because a heat pump cools in long low-temperature cycles and the coil stays wet for hours at a stretch. The city itself splits cleanly. There is the original 1980s build-out on the peninsula, where the flex has now had forty years and the systems are compact and closet-mounted, and there is the newer wave around Grandscape and the Austin Ranch side, where nothing has been in service long enough to accumulate much of anything.

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 The Colony, 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.
The vents smelled like burning on the first cold night. Should we be worried?
Almost certainly not, and we will not sell you a cleaning over it. In an all-electric house that smell is dust burning off the resistance heat strips the first time they run after a long summer, and it goes away within a few cycles. If it lasts longer than that, or smells acrid rather than dusty, call us and we will look properly.
Our house is from the late eighties on the lake side. What is the realistic condition?
Original flex of that era is at the end of a long life. Insulation compressed at every strap, liner often torn at the bends, and a system that was compact to begin with. We scope it and give you a verdict run by run. Sometimes the useful spend here is replacing two bad runs rather than cleaning twenty.
We have a heat pump, not a furnace. Does that change the inspection?
It removes combustion and adds moisture. There is no cabinet or flue to check, so the attention goes to the indoor coil, the drain pan and the first few feet of supply plenum. Heat pumps run long low-temperature cycles that leave the coil wet longer, and that is where a biological problem in a Colony house usually starts.
