Is There an Odor Coming Out of Your Vents?

Mildew on Air Vent What’s that musty smell? Is there a mildew smell in your home and you can’t figure out why? It might be your air ducts. In Houston, TX it’s hot and humid and this can lead to mildew growing in your air duct system. When the A/C turns on and begins to blow out air through your duct system it also blows the odor of the mildew growing inside the system. If you have a sensitivity to allergens you might also suffer sinus and respiratory infections and inflammation in addition to being annoyed by the smell. Condensation along with the over abundance of mold spores are part of the problem. The long warm periods and running your AC system 10 months out of the year also contributes to mold and mildew growth. How do you combat a force that begins with nature and invades your home with the help of such a great technological innovation like air conditioning?

The answer is regular cleanings and in the case of stubborn persistent mold and mildew growth, Ultra Violet Lights. UV lights help kill mold spores as they pass through the Plenum on their way to your ducts and into your home. Ultra violet light is a great germ killer and UV lights can help to keep mildew, fungus, and mold growth down between cleanings. 

Many times our clients ask how often they should clean their systems. Most of the time every few years is enough. If you have a problematic system using a combination of UV lights and cleaning every few years should keep the issue of mold and mildew growing in your system at bay. Occasionally there is a secondary problem that is contributing to mildew growth outside of the usual culprits like condensation and mold spores. A home could have an older system or perhaps ducts that are damaged or defective. Sometimes this leads to excessive moisture build up. This is not usually the norm and most of the time a simple complete cleaning is enough to take care of the mildew and the smell.
