Entrainment is a major cause of condensation and mold in Texas. Entrainment is when an AC contractor installs an AC to large for the square foot if the home. It's all about balance. The AC pulls to much return air and pulls the additional air directly from the attic. This causes the condensation and eventually mold. If the AC tonnage is excessive the only recommended action is replacing the AC to a lower tonnage. But in many cases of slight entrainment an attic air seal and insulation upgrades can resolve the issue. Call me today for a free evaluation. 281-813-0657
