Mold In Air Handler Insulation

Moisture and warm temperatures.

Mold in air handler insulation. Mold in hvac ductwork is also discussed. Hvac blower leaks rust mold air conditioner air handler rust condensate leaks wet insulation mold hazards. The insulation in air handler in my previous home became covered with mold. An air handler is a device that circulates either heated or cooled air throughout a building for the purposes of climate control.

Here are the most common reasons for air handlers sweating so you can stop the condensation. Replace duct board with properly sized ducts. Cures for mold on duct board trunk lines. Uv lights in the air handler the evaporator coil is an ideal environment for biological growths.

See blower leaks rust mold. Mold especially grows on the cold spots that create condensation. And airborne particle mold levels in ductwork where we describe how to test hvac systems and ductwork for mold. Mold on duct board trunk line flir photo of molding supply trunk line.

Condensation on the outside of your air handler can be an effect of an underlying issue. A humid climate along with poor ventilation or anything that traps moisture in your walls and causes condensation can lead to mold in air ducts. Clean and disinfect the ductwork using the proper tools and approved killing agents. The cost to clean air duct systems ranges from 250 500 per home.

Mold grows in ductwork when two things are present. If the black mold in your air vents has spread to the insulation it will need to be replaced. Enough of that moisture was transported to the air handler to saturate the fiberglass insulation. It turned out that the system have a refrigerant leak and the leak meant the system was running almost continuously and producing a lot of condensate.

Eliminate cold air leakage. Leaks in the air handler can cause rust damage and may invite mold contamination in the ahu or in the hvac system ductwork. Mold on air conditioning systems can be avoided. A thorough cleaning of the hvac system after remediation may be necessary to ensure you are preventing the spread of mold throughout the house via ventilation.

However air handler sweating is different. When mold grows on the coil the air conditioner loses energy efficiency. The mold acts as insulation and it will take the a c longer to cool your home. Mold is a common problem for air handlers because mold grows anywhere there is a regular source of moisture.

Moreover the excess moisture can lead to a damaged plenum mold or termites. Air handlers can involve air conditioning units central heating or both. Heating and air conditioning ventilation can fairly evenly distribute mold spores throughout an entire home. Temperatures are ideal and there s plenty of moisture for them to grow.

Perhaps the most important part of the process is to find out what caused the growth in the first place. A warm humid environment has the ideal conditions for mold to form.
