About Jim Locksley

One day when I was walking around my college campus, I saw a group of people with these yellow tripods. At first I thought they might be photographers, but they sure looked like strange ones! I went up and asked them what they were doing, and it turns out they were a group of students from a construction class who were surveying the land for a project. I was fascinated. I was able to sign up for the class the next semester, and while it didn't stick or change my professional trajectory, it did create a new hobby for me! Ever since then, I've been interested in construction, from surveying to management to the actual building. I figured running a blog about it would give me a nice excuse to keep up my interests!

Tackling Mold Growth In Your Air Conditioning System

by Mike Brewer

Keeping your air conditioning system clean also means keeping mold and mildew at bay. When mold and mildew starts to flourish, it can cause a wide variety of health problems for you and other occupants in your home. To prevent this from happening, you'll need to tackle the mold before it has a chance to take hold.

Places Where Mold Can Grow

Finding mold can be a bit tricky because there are so many places where mold can grow. Mold and mildew typically favor dark, damp places, so it's not uncommon to find it in areas of your HVAC system where there's a lot of excess moisture. These areas include the evaporator coil, condensate drip pan, condensate drain and other surrounding areas.

Mold spores can also migrate through the ductwork of your HVAC system, especially if you haven't had your ducts cleaned in a while. These spores can not only establish themselves within the ducts, but they can also escape your HVAC system and settle in other areas of your home.

Fortunately, the majority of mold spores are caught by your HVAC system's air filter. However, a dirty air filter can allow air that would otherwise be filtered to push through the edges of the filter, thus allowing mold spores to travel unimpeded.

Getting Rid of the Mold

Once you've identified the places where mold growth is prevalent, it's time to tackle the task of cleaning it up. You'll need a cleaning solution that is strong enough to neutralize and remove mold. Fortunately, you have several options you can make and have at your disposal:

  • A half-cup of bleach, a quart of water and a tablespoon of mild household detergent
  • A half-cup of baking soda, a cup of water and a tablespoon of detergent
  • A mixture of one part borax and 16 parts water
  • A 50/50 solution of ammonia and water
  • A bottle of white distilled vinegar

If you don't want to mix your own solution, you can always opt for a commercial mold cleaner. In the case of your evaporator coil, you'll want to use a foaming no-rinse solution for removing mold and other debris. This way, you'll avoid unnecessary contact with the delicate coil fins.

Take your cleaning solution and spray it on the affected area. Give it a few minutes to sit, and then use a damp rag or a scrubbing brush to remove the mold. Repeat the process until the mold has been completely removed. If there's mold growth on the evaporator coil, use the foaming no-rinse spray or scrub very gently with a soft-bristle brush.

If you haven't done so already, now is a good time to change your air filter. With a fresh new filter, you won't have to worry about lingering mold spores reestablishing themselves within your AC system. If you're still having problems rooting out mold growth, then you may want to get your HVAC technician or air conditioning contractor, such as those at Anytime Plumbing Services, involved.
