Mold is a pesky, but common issue that occurs in HVAC systems. When moisture gets trapped in the system it can cause mold to grow, it can take as little as 48 hours for this process to begin. If you’ve found mold in your system, the best option is to contact an HVAC professional to come out and help you clean the system. However, here are some general steps to follow in order to remove the mold.

  • You should protect yourself by wearing a mask, this will keep the small airborne particles from entering your respiratory system.
  • Throw out any air filters or insulation that are moist. If these remain in the system the moisture will allow mold to grow again.
