Ask the Expert: Odor Coming From A/C When Turned On

Ask The Expert: Odor Coming From A/C When Turned On
One common problem with air conditioning units is when they give off foul odors while in use. You are probably wondering if all these smells are normal and what cause them. There is only one way to find out! Schedule an A/C inspection with your trusted HVAC experts for knowledge. Different odors have different causes. Here are the typically reported A/C smells and their causes. Your air conditioning unit smells like dirty socks. It is awful for homeowners when their air conditioning unit produces musty odor or that of a stinky sock. Your unit may likely be spreading mold/mildew all over the house. If this is noticeable whenever you run the system, you probably have one of these problems:
  • Mold buildup on the evaporator coil. Condensation happens in the evaporator coil whenever warm air passes through. Dirt and dust accumulation along with condensation creates a perfect breeding ground for molds and mildew. It is important to schedule professional coil cleaning regularly to prevent this problem from taking place.
  • Mold buildup in the ductwork. Mold in your ductwork is an indication of leaks and too high humidity. Sometimes, molds are distributed from other areas and reached the ducts. Whatever the reason is, you should hire an expert to do duct cleaning and provide necessary solutions to prevent molds from building up in that area.
  • The condensate drain line is blocked. If the condensate drain line is clogged, the condensation trapped in the system brings mold and bacteria into life. You will know if the drain line is clogged when water is dripping around the unit and your unit shuts off suddenly. If you do not want to get your hands dirty, hire an expert to remove the blockage for you.
Your air conditioning unit smells like rotten eggs.
  • Rodents or other dead animals are stuck in the air duct. Pests can find their way into your system and get stuck in there. You know when this happens if the odor becomes stronger as you go near the vents and find pet droppings inside the duct. Have a professional remove the animals to get rid of the odor.
