Pasadena is the second-largest city in Harris County and it has the oldest housing stock of any suburb in the metro: median build year 1977, a fifth of the city from the 1950s, 20% from the 1970s. Deer Park next door is 1982. These are single-story houses on one system, built with metal trunk lines and, where anyone has touched them since, flex branches from the 1980s or 1990s. The plenum has been closed for fifty years.
This is the strongest “original and never cleaned” case anywhere in the metro, and it is also the one where cleaning and replacement are hardest to separate without a look. A 1962 Pasadena house has a metal supply trunk that may be in excellent shape — galvanized duct does not age the way flex does — feeding flex branches added in 1988 that are long past saving, and a ductboard plenum that has been shedding fiberglass into the airstream since the Reagan administration. The honest visit is an assessment that says which is which: clean the metal, replace the branches, and replace the plenum if it is coming apart, which is licensed work.
Return air is the other thing. Houses of this era were often built with one return in a hallway, undersized by modern standards, and the system pulls attic air through every unsealed boot to make up the difference. Sealing the boots does more for what comes out of the registers than any cleaning, and a good crew says so.
Pasadena, Deer Park and La Porte sit along the Ship Channel, and the refinery corridor’s particulate is a real difference from the rest of the metro: it settles on windowsills and it settles in the returns. It is a reason to change the filter on time and to use a better one, not by itself a reason to clean ducts. If the registers are blowing visible material, that is the trigger; the corridor just makes it likelier.
Probably, for the metal, after fifty years — and the plenum should be checked for shedding. If flex branches were added later, those are past their life. Ask for the assessment.
It is a filter problem first. If the supply registers blow it into the room, then the ducts need it.
