Why does my car AC smell musty or moldy?

A musty or moldy car AC smell in Miami is almost always caused by mold and bacteria growing on a damp evaporator core, or by a clogged cabin air filter. Our high humidity makes this extremely common, since moisture condenses inside the AC system and never fully dries out. The smell usually hits hardest in the first few seconds after you turn the AC on. The fix is straightforward: replace the cabin air filter and treat the evaporator with an antibacterial cleaner that kills the mold at the source. In stubborn cases the evaporator housing needs a deeper flush. At Motoro Cars, our technicians clear the odor and replace your filter so the smell does not come right back. Driving with the AC off and the fan on for a few minutes before parking also helps dry the system. Call (786) 634-2002 or visit motorocars.com.
