You know that unpleasant smell of mildew? It is something nobody wants to experience, especially in your own home and coming from your own air conditioner!

Every time your AC comes on, does the air leaving your vents stinking with a musty, mildew-like odor? Are you wondering what in the world it could be? Most likely it’s the smell of mold and/or mildew, which is bad news because your AC is probably distributing mold and mildew spores throughout your home, which can be particularly harmful to your health, especially if you have allergy issues.

One common cause of this can be a dirty evaporator coil, and the signs this is the problem can include an iced up evaporator coil, resulting in weak airflow coming out of the supply vents. If the evaporator coil, the part of your AC that cools your air, gets dirty (and it usually does), it becomes a breeding ground for mold. Mold grows when it has 4 things, including food (organic materials like dust and dirt), darkness (UV rays kill mold), moisture, and warm temperatures (80 degrees or above), and your evaporator coil naturally has 3 of these elements already in that the coil is located in a dark area (the indoor unit), the blower constantly flows warm air over the coil, the condensation (moisture) forms on the cold coil when the warm air flows over it, and all that’s needed is food for the mold (such as dirt and dust). Unfortunately, dust and dirt usually sticks to the coil because of the condensation, giving mold the food it needs (and this is less likely to happen if you regularly change your air filter).

The solution is to have your evaporator coil cleaned by a professional, and at Altman’s Cooling and Heating our professionals will clean the coil as part of a maintenance visit, something your AC needs at least once a year. You can also prevent mold from growing on your coil again by installing a UV germicidal lamp.

A clogged condensate drain line can be another problem and the signs that this is the problem includes that your AC shuts down after running for a short while (because water is flowing over the condensate pan and triggering an emergency shut off switch) or if you see water pooling around the inside of your unit. When enough condensation forms on the evaporator coil, it drops into a drain pan and then exits out a drain line. If your drain line gets clogged (because dirt from the coil often falls back into the pan) then water backs up into the drain pan, and then mold has everything it needs to grow (food, moisture, darkness, warm temperature).

The solution to this problem is to clear the condensate drain line, which is always best done by the professionals from Altman’s Cooling and Heating.
