Managing mold in commercial HVAC systems is part of any good, solid Indoor Air Quality (IAQ) process. In fact, it is specific in by national organizations that managing for bacterial growth needs to be part of routine maintenance.

The dangers of not managing mold and mildew growth in HVAC are far more than “dirty sock syndrome” where HVAC systems take on a moldy, musty odor. In fact, mold spores can be dangerous, causing difficulty breathing and also can cause major damage to buildings and infrastructure.

Given the recent events of hurricane Sandy, we are offering some steps to making sure commercial HVAC systems are free of mold growth and odor. When power is lost to commercial HVAC systems, mold can begin to grow in as quickly as 24 hours. If left untreated it can quickly become a major issue.

Take these 4 steps to manage mold in commercial HVAC systems.

1. Clear all water sources. Identify any additional water or high humidity sources and fix them.
2. Clean surfaces with an EPA registered disinfectant specially labelled form Mold and mildew cleaning in HVAC systems. Make sure to clean all surfaces per directions.
3. Apply an EPA registered mold growth inhibitor. Make sure this is labelled for HVAC use and is OK to be applied while buildings are inhabited, otherwise you will have to vacate buildings.
4. Apply an odor cleaner and remover. This will make sure any lingering odor will be neutralized.
