If you are using the blue air filter it is just a matter of time before your evaporator coil has to get cleaned out. This type of filter does a poor job protecting your air handler or furnace. You should replace this filter every 30 days. It only takes two or three dirty blue filter changes to start clogging up your evaporator coil. These filters are very cheap and you will save money in the short term, but in the long run you will spend much more hiring a professional to clean out your unit.

My Furnace Is Leaking Water In The Attic, What Do I Do?

Most people don't know how humidity is removed from your home. The evaporator coil in your attic also acts a dehumidifier. All the moist hot air that passes through your coil in the attic it condenses into water. That water is then removed from the space that is being cooled. If your unit is not draining properly, you will have a water leak. A water leak is usually caused by a restriction in your drainage pipes. There are many different places a blockage can occur. One of the key areas where a blockage starts to develop is inside your evaporator coil. In your evaporator coil there is a drain pan. After months of condensation, sludge, slime, & bacteria will start to build up inside your unit. That sludge then circulates throughout all the inter connected pipes in your home. If you remove the panel that covers your evaporator, you might be able to get to the drain pan. You can use a wet vac to vacuum out the sludge from the drain pan. If the water leak problem is not corrected quickly, your ceiling could fall down.

Spores from mold such as stachybotrys or black mold often become trap within wall spaces when your air conditioning condensation leaks in your attic. It can stay trapped behind your walls inactive for many years. However the accumulated moisture from leaks, flooding, or high humidity can activate these dormant spores causing mold to grow and reproduce. Black mold reproduces by creating microscopic spores which carry harmful chemicals called mycotoxins. The spores are released into the air where they circulate, and land on household surfaces & food. Mycotoxins that come into contact with the skin may cause irritations and lesions. If inhaled these toxins are carried into the lungs and permeate the air sacs, this onset makes breathing difficult and painful. A condition that is only worsened as fluid begins to accumulate. Mycotoxins that have fallen into food products may be ingested, inflaming the entire digestive system. Through any of these pathways these dangerous mycotoxins may find there way to the network to the network of blood vessels that nourish our brain. Once inside an artery it may travel out of the bloodstream and into the nervous system. These mycotoxins affect the passage of signals between brain cells, causing disruption of thinking, memory, and movement. Households that have been exposed to moisture, should be tested for the presence of mold.
