Some Florida homeowners are running into a unique problem with imported Chinese drywall. The drywall was made from waste material from scrubbers on coal-fired power plants in 2004 and 2005. Unfortunately, it appears some of this material can leak off as sulfur and become sulfuric acid when it hits the moisture on an air conditioner coil. As a result of these gases, one homeowner has had to replace four air conditioner coils and one refrigerator. Another homeowner is reporting damage to his copper electrical wiring. A spokesman for the Lee Building Industry Association said homeowners should direct all concerns directly to their builder.
