AC Mold Inspection Fort Lauderdale, FL

It is inside the standard inspection price rather than charged as an extra, because in this county the system gets examined on every job regardless of what the call was about: $325 for a condo up to 1,000 square feet, $425 for a home up to 2,000, $525 up to 3,500. That includes a sample taken at a supply register where the survey indicates one, the laboratory analysis and the outdoor control. Multi-zone properties are quoted on the number of independent systems rather than the floor area, because each one is effectively a separate building.

The commonest reason is that the new system is larger than the house needs. Replacement equipment is frequently specified by matching the tonnage of whatever came out, and a house that has had its roof, windows or insulation improved since then needs less cooling than it did. The oversized machine satisfies the thermostat in a short cycle, and because moisture removal does not reach full rate until roughly three minutes in, the house ends up cool and damp. The symptom is a house that feels clammy at a temperature that used to feel fine.

Very often yes, and it is the single most repeated story in local complaint threads. The line carries water that has just been condensed out of warm humid air, and biological growth inside the pipe gradually closes it. When it blocks, the pan overflows into whatever is underneath: a ceiling, a closet floor, a garage, or the insulation around the air handler. That water is not noticed for weeks or months because none of those places gets looked at. The prevention is trivial and the damage is not, which is why it has its own section in the report.

Sometimes, and less often than it is sold. Duct cleaning is genuinely indicated where there is visible growth or deposition inside the duct, where the system has been running with a failed filter, or after construction dust or a water event has entered the system. It is not indicated as routine maintenance and it does nothing at all about humidity. The more important point: if fibrous duct lining or insulation has been wetted, it holds moisture within the material and cleaning does not recover it. That is a replacement, and a cleaning quote for it is money spent on the wrong job.

Easily, because the air handler is upstream of every room. A wet coil, a pan holding standing water or a saturated section of plenum lining sits directly in the supply air path, so whatever is growing there is distributed to every register in the building on every cycle. The recognisable pattern is a smell strongest in the first minute after the system starts and then fading, and a smell that is present in every room roughly equally rather than in one. Both of those point at the system rather than at any single room.

A correctly placed and correctly sized germicidal lamp aimed at the evaporator coil will keep the coil surface clearer of biological growth than it would otherwise be, which is a real if modest benefit on a system that fouls quickly. What it will not do is address standing water in the pan, a blocked condensate line, wetted duct lining or growth anywhere else in the building, because it only affects the surfaces it directly illuminates. It is a maintenance aid for one component and it gets sold as a whole-house solution.

No, and a fair number of these calls should be one instead. An air conditioning contractor measures refrigerant charge, airflow and electrical performance, and can clean a coil, clear a line and repair a pan. We do none of that. What we do is establish whether there is a moisture and growth problem, where its water is coming from, and what it would take to close it, in a document with laboratory results attached. Where a call is plainly a maintenance issue we say so on the phone rather than booking an inspection for it.

It changes the consequences considerably. An attic air handler sits in a space that is hot and humid for most of the year, so the cabinet, the plenum and every duct run are working against a much harder condition than one in a conditioned closet. Duct insulation that has been compressed or has slipped will condense on the sheathing behind it. And a pan overflow discharges into a ceiling rather than onto a floor, which is why it is discovered as a stain rather than as a puddle. Attic systems get more of the survey time for those reasons.

Frequently, yes, and it is usually the cheaper answer. Where the finding is that the cooling equipment is oversized for the load, a whole-house dehumidifier on a humidistat controls the variable that is actually causing the problem rather than fighting it with a colder setpoint. It is a fraction of the cost of new cooling equipment and it does not depend on anyone agreeing the existing system was wrongly sized. We have no interest in either purchase, which is why the report sets out both and lets you price them.
