How to Prevent Mold Growth in Your Home

Mold growth is a common issue that concerns Florida homeowners. Organic materials and moisture are the two main things molds need to grow. Unfortunately, these two components are easy to find in most Florida homes.

How can you prevent mold from growing in your house if you live in Florida, one of the most humid states in America? Apart from keeping your air conditioning running and in good health, here are a few more measures you can take to keep your humid house mold free:

1. Prevent condensation

One frequent cause of moisture and humidity in a room is condensation. It forms on cold surfaces when the water vapor in the air cools down and becomes liquid. This normally happens when there is poor air conditioning. You will often see condensation on concrete walls, windows, water tanks and metal pipes.

The first way to reduce condensation in your environment is by keeping the temperature around you warmer. You can achieve this by installing insulation. You can also insulate surfaces where condensation takes place like covering the metal pipes.

Prevention Tip: Keeping the humidity in your home low will help prevent molds.

2. Prevent water leaks

Water leakages can also cause moisture problems in the home. This includes leaking walls, roofs, taps, pipes or shower. Mold prevention starts by identifying such leaks and fixing them as soon as possible. You can either do it yourself or hire a specialist to inspect the whole house and see if there is any leakage.

Prevention Tip: Watch for signs of moisture along baseboards, under sinks, near showers and bathtubs. Keep and eye on window sills, especially after heavy rains.

3. Avoid storing wet laundry

The other reason molds are multiplying in your environment is due to the wet laundry, such as bathing suits or pools towels, in your room. You should dry your clothes as soon as you are done washing them. Piling them while still wet for long will create humidity in the environment and breed molds. The clothes waiting to be washed should also be dry.

If you can, it is advisable to dry your clothes on a clothesline away from the house. When you hang them inside, they will not dry quickly and the moisture from them will evaporate into the air to raise the levels of humidity in the house.

Prevention Tip: If you air-dry laundry inside your home, make sure the room you use for drying is well ventilated and your AC is working properly. 

4. Mold-resistant products

This is a great tip if you are building a new home or renovating an old one. Making use of mold-resistant products like mold-resistant Sheetrock or mold-resistant drywall and mold inhibitors for paints will equally get rid of molds even in a humid environment.

Traditional drywall is made up of a gypsum plaster core pressed between papers. However, the mold-resistant drywall has no paper. The gypsum is also covered in fiberglass. The surface is purely water resistant.

Prevention Tip: If you are building or renovating in an area prone to humidity, or any other form of wetness, moisture-resistant drywall is a good way to avoid mold problems.

How AC Works



1. Return Air Register
Air from the home passes through the grille then enters the air handler and is heated or cooled and dehumidified. Your filter is normally in the grille and should be cleaned or replace monthly.

2. Air Handler
The air handler is typically located in your attic, hanging in your garage or stands vertical in a closet or your garage. The air handler consists of a blower which moves the air, the evaporator coil which cools and dehumidifies, a drain pan which collects the moisture taken out of the air and head strips which heat the air.

3. Supply Air Register
Cooled or heated dehumidified air is distributed through your home by the supply air grilles. Most supply grilles are directional to move the air across the ceiling to displace the heat load of the room.

4. Refrigerant Lines
These are two copper lines which carry the refrigerant to and from the air handler to the condensing unit outside. Once carries a cool gas refrigerant and the other carries a warm liquid refrigerant.

5. Drain Line
The drain line carries the moisture taken out of the inside air and dispenses it outside through a PVC pipe. There is normally a P-Trap outside your home which creates an air trap to allow your unit to drain properly. It is recommended to clean this trap out regularly.

6. Condensing Unit
The condensing unit is the heart of the system. It consists of an outdoor fan, condensing coils and compressor. The compressor compresses the refrigerant into a hot gas which is distributed through the coils and cooled by the fan. The refrigerant then turns into a warm liquid which is transferred through the copper line back to the air handler unit.
