The license line, the price, the $99 special, sanitizing, floods, and whether you need any of it. Short answers, with the longer pages linked.
Not as such. Under 16 TAC §75.100, cleaning the air distribution system between the supply plenum and the supply grilles, and between the return grille and the air handler intake, may be done without an air conditioning contractor license, provided nothing is cut, no wiring is touched and only removable grilles are taken off. Cleaning the coil or blower, opening the air handler, cutting an access panel, and applying any disinfectant or anti-microbial inside the system are licensed work and belong to a TDLR-licensed contractor.
There is none to show: this site performs no work and holds no license, and Texas rules forbid displaying a licensee’s number on a business it does not belong to. Where a job includes licensed items, the contractor doing them quotes under their own license, and the number belongs on their paperwork. Ask for it there.
The EPA says it has never been shown to prevent health problems and does not recommend it routinely. What it demonstrably does is remove accumulated material — remodel dust, debris from pests, decades of settled dust. This site sells it as that and nothing more.
There is no interval the EPA supports. Clean when one of five things is true: a remodel or new build, pests, visible debris from the registers, confirmed mold on hard-surface components, or decades on original ductwork that has never been opened. The triage page walks through each.
Roughly $390 to $800 for a one-system house and $860 to $1,325 for a two-system two-story, duct side only, with coil and blower cleaning quoted separately by a licensed contractor at $300 to $900 per system. The pricing page has the table and an estimator.
Not for a whole house. It covers one air handler’s supply registers with a vacuum and a deodorizer, and the returns, plenums and second system are added on the driveway or skipped. The KPRC 2 investigation of a Humble homeowner’s $199 job that became $960 in cash for “mold” is the standard version of the story.
Four to seven hours for one system in an ordinary house, most of a day for two. Houston’s Better Business Bureau put a legitimate job at several hours when the local TV station asked. Ninety minutes means the returns and plenums were skipped.
Two problems. Applying it is licensed work in Texas, so an unlicensed duct crew may not sell it. And the EPA says no chemical biocide is currently registered for use inside internally insulated ductwork, which is what nearly all Houston flex duct is. For a system that was simply dusty, decline it.
No. Wet flex duct and wet ductboard cannot be dried and cleaned to any standard; they are replaced, and the air handler is inspected by a licensed contractor. Mold inside wet ducts above 25 square feet is separately licensed remediation in Texas. The flex duct page covers what a flooded system needs.
No. It connects you with one independent duct and dryer vent cleaning contractor covering your zone of the metro, who quotes and performs the job under their own business name. Licensed items are done by a licensed air conditioning contractor under their own license.
All of the five-county metro, sold one zone at a time: Northwest, North, Northeast, East and Southeast, South and Bay Area, Southwest, and Inside the Loop. The service-area pages say what the housing stock in each part of the metro was built with.
Usually yes, and it is the cheaper half. $99 to $189 through a wall, more through the roof, on the same visit. A dryer that takes two cycles or a vent hood that has stopped closing is a reason on its own.
Often, once. Builders run the system during finishing, and drywall dust, sawdust and insulation end up in the runs. If the registers blew dust for the first few weeks, that is what you were seeing. One cleaning after move-in and then nothing until one of the five triggers applies.
Systems counted, supplies and returns counted, plenums named, negative-air equipment named, duration stated, and every licensed item labeled as licensed with the contractor who holds it. The checklist is the thing to compare it against.
Say what you are seeing and which part of the metro. The contractor covering your zone sorts out the rest, in writing, before anything is booked.
