How To Remove Mold From Air Conditioner Ducts
Molds, such as black mold, are always present in the environment. When molds encounter areas with the right conditions, they may multiply to the point where they become an issue for building owners. Dust and moisture in the vents of an HVAC system can provide a fertile breeding ground for mold. If not removed promptly, the forced air from an HVAC system may spread mold to the rest of your building.
Removing Black Mold From HVAC Systems
Eliminating mold from an HVAC system is a multi-step process.
1. Confirm You Have a Mold Problem
Before you spend time and money attempting to eliminate a mold problem, it is a good idea to confirm that you have one. Inspect your HVAC system for signs of mold and moisture. Additionally, you may notice mold signs throughout your building. A musty odor is often one of the first signs of a problem. You may also notice stains or dark spots on walls, ceiling tiles, or carpets. Pay particular attention to any areas with high moisture levels, such as kitchens and bathrooms, or water damage.
2. Remove Moisture
Shut down your HVAC system. Make sure anyone working on the HVAC system is equipped with an N-95 respirator. Remove and replace filters or insulation that is wet. Use a wet/dry vacuum to remove any standing water in the air ducts. Repair anything that is leaking or any drainage systems that are clogged.
3. Clean the System
Thoroughly cleaning your HVAC system will help remove mold and dirt that provides food for mold growth. Use a disinfectant that is registered with the EPA and labeled for HVAC use. Use a mechanical coil cleaning system to remove debris from the evaporator coils. As you clean ducts, separate them with bladders so that spores from the ducts you are cleaning don't spread to the ducts you already cleaned.
4. Prevent Mold From Returning
Prevent mold from coming back by applying a mold and mildew inhibitor to all parts of your HVAC system. Choose a product that is EPA registered and labeled for HVAC use.
5. Vacuum the Ducts
Use a vacuum with a HEPA filter to remove any debris left behind from cleaning.
Prevent Future Mold Problems
Controlling moisture is the key to preventing future mold problems in your HVAC system. Contact an HVAC repair company in Bountiful, UT, to diagnose and repair the issues that caused your system to accumulate moisture. Make sure your drain pans are properly sloped and regularly cleaned. Replace your air filters regularly. Keep areas below air intake clean and free of moisture. Have your HVAC system professionally inspected at least once per year.
When To Call a Professional
Mold can be difficult to remove completely. If your mold problem keeps coming back, you may need to contact a professional mold remediation company to perform a thorough cleaning.
Molds, such as black mold, are a normal part of the environment. However, mold that grows rapidly can create problems for property owners. Removing mold and addressing moisture issues promptly is the key to avoiding additional damage to your building.
