How the cooling fails in Hollywood
Original ductwork is the defining piece of equipment in Hollywood, because the cooling has been replaced two or three times since 1969 and the duct almost never has. What that produces is a modern, efficient condenser and air handler blowing into a distribution system designed for a different machine, with insulation that has aged out and joints that have opened. In the beachside blocks the picture is different again: through-wall and packaged terminal units serving one room each, with no whole-house dehumidification anywhere in the building and a wall sleeve detailed half a century ago.
Against that, one piece of building science is worth stating flatly because it is counter-intuitive enough to be missed: an oversized air conditioner dehumidifies worse than a correctly sized one, despite carrying more capacity on its nameplate.
The reason is timing. Moisture removal does not reach its full rate until roughly three minutes into a cooling cycle, because the coil has to get properly cold and wet before it strips much water out of the air crossing it. An oversized system reaches the setpoint and shuts off before it gets there. The house is cool. The house is also damp. The Florida Solar Energy Center put a worked figure on it: a building genuinely needing two tons, given four, is dehumidified worse by the larger machine despite twice the nameplate moisture capacity.
That is why so many of these calls in Hollywood describe a problem that started after new equipment was fitted. The other half of the job is more prosaic and more common still: the condensate line, which carries water just condensed out of warm humid air and closes gradually with biological growth until the pan overflows into a ceiling, a closet floor or a wall. It is the highest-frequency failure in this county and the cheapest to prevent.
The commercial position in Hollywood is the one published on every page of this site, because the rate card is not a Fort Lauderdale rate card. A flat price by property size, agreed before anyone drives out, with the accredited laboratory fee already inside it. It does not rise if the samples come back positive, nothing is added for the drive, and we take no payment of any kind from anyone who removes mold.

What Hollywood itself changes
The buildings in Hollywood
Hollywood has a median build year of 1969 across 72,843 housing units, which places most of the city in the first generation of Florida housing designed around central air conditioning from the outset rather than having it retrofitted later. That sounds like an advantage and it cuts both ways. These houses were designed to be cooled, so the envelope is tighter than the pre-war stock further south, but they were designed to a 1960s understanding of it: ducts sized generously, equipment specified by rule of thumb, and very little attention paid to what happens to humidity when the machine is satisfied early. Forty-three per cent of the stock is single-family detached and another 19% sits in buildings of fifty units or more, so the city carries both the single-storey slab house and the mid-century beachside block, and those two fail in completely different ways.
Where it hides in these buildings
The 1960s single-storey stock here puts almost everything that matters out of sight in two places. The first is the attic, where the air handler frequently sits along with duct runs that were insulated to the standard of the day and have had sixty years to compress, slip or split. The second is the slab edge, where a terrazzo or tiled floor meets an exterior block wall, which on a house of this era has no capillary break worth the name. Growth at a wall base behind furniture is the commonest Hollywood finding and it is invisible until something is moved.
Licensing, and who signs it off
Mold assessment is licensed by the state rather than permitted by the town, which is the opposite of how plumbing or electrical work is handled here. No Broward municipality issues a mold permit or keeps a mold register: the assessor licence comes from the Florida Department of Business and Professional Regulation under Chapter 468 Part XVI, it is searchable on the state register, and section 468.8419 bars the holder from remediating a structure they assessed within twelve months. That is identical at every address in the county and we will say so rather than inventing a local office. What Hollywood adds is a documented flood history and a large stock of 1960s buildings that have been altered repeatedly, so the question of when a water event happened comes up here more often than anywhere else in the county.
