Southwest Houston inside the Beltway is where the 1970s building boom landed: Sharpstown is 48% 1970s housing, Braeburn 43%, Alief 40%, Westchase 28% with a lot of 1980s on top. Together they are 75,000 units, most of them single-story or modest two-story houses on one system, built in the decade when flex duct and ductboard plenums became standard, and the largest concentration of original 1970s duct systems anywhere in Houston.
A 1974 house in Sharpstown or Alief was built with a ductboard plenum, a short metal or ductboard trunk, and flex branches — the first generation of the construction that the whole metro uses now, fifty years on. The air handler has been replaced two or three times; the runs have not, because each replacement was a cheaper bid without them. The plenum has never been opened. This is the “original and never cleaned” case at its largest scale, and the honest first visit is an assessment that expects the flex to be past saving, the plenum to need a look for shedding, and the metal, where there is any, to clean well.
These are also the metro’s most affordable neighborhoods, which matters for the conversation: a $700 cleaning of duct that is delaminating is not a saving against a replacement, but a replacement is a large bill on a modest house. A good contractor lays out both honestly and lets the owner choose. What they should not do is sell the cleaning as though it were the fix.
A large share of this housing is rental, and rental attics get opened even less often than owner-occupied ones. A tenant with dust from the registers is a landlord’s duct question, and the assessment-first logic applies doubly: a landlord should know whether the system needs a $600 cleaning or a $5,000 replacement before the next lease. Westchase and the western edge of Alief have 1980s and 1990s stock and some 2000s infill, where a first cleaning still makes sense with the runs checked.
Assessment. Expect flex past its life and a plenum that may be shedding. The contractor should give the owner both numbers, cleaning and replacement, and say which is honest.
Thirty-six years on original flex is past rated life. Assessment; likely branch replacement plus cleaning of the rest.
