I will give you some ideas how to check for mold in your home.
Step 1 The first place you should look is the most common place for mold to grow which is the air conditioning system. That is not to say that you might have mold growing in other parts of your home. Despite the efforts you make to keep the air conditioning system clean mold can still grow in it. The humidity and darkness in the unit offers strong possibility of promoting mold growth. The air conditioning system should have a metal panel that covers the air conditioning evaporator coil. If you remove that panel and a musty odor comes from the unit more that likely there is mold in the unit. Also if you see an accumulation of black and green spots more that likely there is mold in the unit. I recommend a professional clean the air conditioning system at least once a year. This will help prevent and control mold growth. The air conditioning technician will remove the evaporator portion of the unit and clean it with a special chemical that will remove any mold and dirt.
Step 2 The second place you should look is in the bathroom. Remember mold thrives in humid areas. If there is a leak in the sink drain or behind a wall the humidity will invite mold to start growing. It will continue to grow until the leak is controlled and the mold is cleaned up. Many times water drips continuously from a leaky toilet onto the floor. If the floor is wood it can be even more inviting to mold. Look for black or green spots in the bathroom cabinets, under toilets and behind decorative items like frames where dark areas exist. The bathroom should be cleaned consistently with a cleaning agent that contains chlorine to help control and eliminate mold growth.
Step 3 The third thing you should look for is any leaky roofs, leaky air conditioning ducts, leaky pipes, or leaky drains. Anywhere moisture can accumulate in an area consistently will invite mold. The potential for mold growth in these areas is high. If you have a leaky roof and water soaks through the sealing mold will start to grow and travel with the moisture spot. If the air conditioning ducts is leaking onto the sealing mold will start to grow. If there is any leaky pipes, or pipes with condensation they will sustain mold growth. Any leaky drains in sink cabinets that are not fixed will penetrate through the cabinet and promote mold growth. If you find any of these areas in your home the possibility of mold growth is high if it has not already begun growing.
