Does your home smell like rotten eggs or ammonia (sometimes a sweetish smell)? Is it more noticeable when entering
your home and then seems to dissipate? The level of odor varies greatly in each home as does each person’s ability to
detect the odor. Of course, the strength of the odor also depends on how much drywall was used in the home.
Significantly, some homeowners report no smell, but their home clearly has Chinese drywall. In short, do not rely on
your nose alone, particularly since many develop olfactory fatigue after being exposed to Chinese drywall.
One of the telltale signs is corrosion/pitting of the air conditioner evaporator coils (which are located inside the air
handler). Many owners are first advised of a freon leak, and as the corrosion progresses, evaporator coils eventually
need replacement. An examination of the coils typically (but not always) reveal a black sooty deposit, which may also
appear on the freon line. Chinese drywall also corrodes electrical wiring.
