AC Causing Mold in Las Vegas Home
Air conditioning systems in Las Vegas cause mold in homes through three mechanisms: condensate line failures that release water inside ceilings, walls, or mechanical rooms; evaporator coil contamination that distributes mold spores through the duct system; and duct condensation from inadequate insulation that creates wet surfaces inside the ductwork. Any of these can create a significant mold problem in a home that otherwise has no visible moisture issue.
Condensate line failures are particularly insidious because the water releases inside the structure rather than on a visible surface. The condensate pan overflows, water enters the ceiling assembly or the wall cavity behind the air handler, and mold establishes over the following weeks before any symptom appears. I find this situation regularly in Las Vegas homes with air handlers installed in interior closets or attic spaces where condensate pan overflow has nowhere visible to drain.
How to Know If Your AC Is the Cause
If mold conditions are found near the air handler location in the ceiling below an attic-mounted unit, in the wall behind a closet-mounted unit, or in a utility room adjacent to the system the condensate system is a likely cause. A musty smell tied to system operation points to coil or duct contamination. Both can occur simultaneously in a system that has been operating with maintenance deferrals. A homeowner in North Las Vegas had mold in the ceiling below their attic air handler and HVAC mold simultaneously from a system that had not been serviced in three years.
