Preventing Mold Issues in Your HVAC System

Mold-prevention experts tell us that reducing water/humidity/moisture is the key to preventing mold.  The cleanup costs for black mold or any toxic mold are invasive, time-consuming and expensive.  Preventing the problem in the first place is much easier and affordable.  These steps will help prevent the moisture problems in your HVAC system that can lead to mold problems.

Inspect and Clear the Drains Monthly

When the air conditioner is running, large amounts of water are condensing on the indoor coil located in the furnace or air handler.  It functions something like a dehumidifier except that the hot air is carried outside by the refrigerant.  Condensed water collects in a drain pain and is removed through a drain line that empties into a drain in the floor.  If the drain pan, drain line or floor drain become blocked, water will collect and become a breeding ground for mold.  Check these items monthly to make sure that water is draining as it should.

Clean the Coil Yearly

The indoor coil collects dust that sticks to it when its wet.  That dust holds moisture and also creates a good host for mold.  An HVAC professional will thoroughly clean the coil and the entire furnace/air handler, eliminating the opportunity for mold to grow as well as increasing the performance of the system.

Seal the Duct Work

When the duct work was installed, the seams and connections were sealed and/or taped. With time, that tape or sealant will fail, causing leaks in the duct work where moisture and dust can enter.  This may be a job you can do yourself, if you are comfortable with DIY projects.  Be sure to use professional-quality duct tape which is usually made with heavy-duty foil.  Use sealant designed specifically for ducts too, so that it will have the ability to flex, expand and contract while maintaining the seal.
