Mold is a type of fungi that can grow anywhere moisture is present. Mold reproduces through omnipresent spores that travel through the air and settle in damp or moist areas, creating solid mold colonies. Exposure to mold can be very dangerous to your health by causing respiratory distress and severe allergic reactions. Air duct cleaning service professionals must remediate---or, remove---mold from the air ducts that service your home's heating, ventilating and air conditioning (HVAC) systems.
Air Duct Mold Remediation
The United States Environmental Protection Agency (EPA) recommends that you avoid attempting remediate mold from air ducts as an independent or do-it-yourself task. Instead, you should hire an air duct cleaning service. Air duct cleaning service providers are trained to navigate HVAC systems, handle mold and remove it using a high-powered vacuum device. Your mold removal project may require chemical biocides to kill the solid mold colonies in your air ducts.
Choosing a Cleaning Service Provider
Investigate several air duct cleaning services before deciding which service provider will get your air duct mold remediation contract. The EPA suggests you compare three or more different service providers before you settle on any one. Question the air duct cleaning services about their familiarity with your particular ducts. Make sure they are licensed within your state or territory, if required.
Ask which biocides the air duct cleaning service provider intends to use for your mold remediation project beforehand. Find out the biocide's potential side effects and other consequences before signing off on any procedures. This is an important consideration for your home health and safety.
Air Duct Mold Removal Evaluation
Thoroughly inspect your air ducts before the mold remediation. Wear goggles and an N-95 respirator mask as you look around inside your ducts with a flashlight. Remember where mold colonies are growing. Look around inside your air ducts again after the mold remediation to make sure there are no mold colonies. Your air duct cleaning service should provide a general cleaning as well. Consult the EPA Post Cleaning Consumer Checklist in Resources and make sure you can answer "No" to every question.
Air Duct Mold Remediation
Keep your air ducts dry and free of excess moisture. Check for condensation---exhibited by tiny beads of water---in your air ducts. Use a dehumidifier if the air in your home is too humid and encourages condensation or mold growth. Consider using insulation materials wherever applicable, as they may also help fight condensation. Installing exhaust fans can also help keep stale, humid air out of your ducts.
Check for any leaks or standing water sources that may be dampening your air ducts or HVAC system as well.
