What the equipment in Coconut Creek can and cannot remove
Split systems throughout, plus a meaningful share of manufactured homes at 4.4% of units, which run their own equipment and their own failure pattern. In the older houses the duct is as likely to be the issue as the machine. In the newer ones the sizing question dominates, for the reason it dominates everywhere in this county: a replacement chosen by matching what came out, fitted to a building that has been improved since.
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 Coconut Creek 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 Coconut Creek 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 Coconut Creek itself changes
The buildings in Coconut Creek
Coconut Creek sits at a 1989 median across 27,340 units, and that number lands the town squarely on the crossover. A meaningful share of the housing went up before Hurricane Andrew and the strengthened code that followed in 1994, and a meaningful share went up after. Those two cohorts behave differently enough that a diagnosis correct for one is frequently wrong for the other. The pre-1994 houses leak air, which means they dry themselves out to some extent and also means humid outdoor air finds its way in continuously. The post-1994 houses do neither, so whatever gets in stays until the equipment removes it.
Where the water comes from
The town is laid out around a network of lakes and water management tracts, which is characteristic of building on drained land in this part of the county. That gives a good deal of the housing a water body within a short distance and a correspondingly high local humidity at ground level in the early morning, which is when the lowest surface temperatures of the day coincide with the highest relative humidity. It is a marginal effect on its own and it narrows the margin on a building that has something else wrong with it.
Where it hides in these buildings
The mixed stock means the survey has to establish which kind of building it is in before it can decide where to look, and the giveaway is usually the windows rather than the date on the record. A single-glazed aluminium frame with no thermal break is a cold surface in an air conditioned house and condenses on its interior face and on the wall immediately below it. An impact-rated post-1994 assembly does not, and moves the problem elsewhere.
