What the equipment in Parkland can and cannot remove
Modern split systems, frequently multi-zone on the larger houses, and the zone count rather than the floor area is what shapes an inspection here. The imported wallboard issue is tied directly to the equipment: sulphur compounds emitted by that product corrode copper, so an evaporator coil that has failed well ahead of its expected life on a house of this age is a recognised indicator. Where that is the picture, the smell people arrive describing is not fungal and no remediation will address it.
The reason that matters is a gap between two numbers, both from the Florida Solar Energy Center at the University of Central Florida. Through the hot months, with cooling running, indoor relative humidity should not exceed 55% during the day on a regular basis. And the great majority of mold species need a material moisture content corresponding to a relative humidity of at least 70% to grow at all.
Note where that second number is measured. Not in the room. At the material. Air holds less moisture as it cools, so the film of air against a chilled surface sits at a far higher relative humidity than the room average. A wall at 68F with 78F room air at 55% is close to saturation at its own face, and it does not need a leak to get there. That is the mechanism behind almost every complaint where nobody can find a source.
So in Parkland we read surface temperatures with an infrared thermometer alongside the room air, calculate the dew point of that air, and record the margin at every surface that has one worth recording. FSEC also give the point at which cooling alone stops being enough: sustained readings of 70 to 75% mean dehumidification rather than a colder thermostat, and turning the thermostat down at that stage chills the surfaces further and makes it worse.
The commercial position in Parkland 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 Parkland itself changes
The buildings in Parkland
Parkland holds the newest housing stock in Broward County, at a 2006 median across 11,501 units with 84% of them single-family detached. Building to the 2002 Florida Building Code produced the tightest residential envelopes in the county: impact-rated glazing, well-sealed sheathing, minimal accidental air leakage. Those are excellent buildings and they concede nothing to a mistake. A house that cannot leak air cannot dry itself, so anything that puts moisture inside it depends entirely on the mechanical system to take it back out again.
Where the water comes from
On a 2006 house the envelope is generally doing its job, so water rarely arrives from outside. What arrives instead is humidity, and it arrives through the routes a tight building still has: an unbalanced ventilation arrangement, a duct system leaking into or out of an attic, or an exhaust fan running without make-up air and pulling the whole house negative against a 73F dew point outside. All three put outdoor air into a wall cavity without anything resembling a leak.
Where it hides in these buildings
The difficulty in Parkland is that nothing looks wrong. Finishes are intact, the building is young, and there is no visible history to follow, so almost the entire survey rests on instruments. The two things worth opening are the least glamorous: the air handler cabinet, and a switch or socket plate on an interior wall, because blackened copper behind one is the first accessible indicator of the imported drywall question in a house of this vintage.
