There’s a Smell Coming from My Cincinnati Air Conditioner


Have you noticed strange smells in your home when your AC is running? Some air conditioner smells can cause irritation and unhealthy indoor air quality issues inside the home. Here is a look at common smells associated with air conditioning systems, what causes them, and what you can do to prevent these odors!

Types of Smells

Smells Like Feet

If the smell coming from your air conditioner is musty or smells like dirty socks, you could have stagnant water collecting in your AC unit. Water may pool near the evaporator coils and is a breeding ground for bacteria, mildew, and mold. Nelson Comfort offers a coil cleaning service to help eliminate odors and improve the efficiency of your coils.

Burning Smell

If you smell a burning odor, you might have a mechanical issue with the fan or compressor in your air conditioner. Nelson Comfort will diagnose your system and determine what needs replaced before a fire starts.

Prevention Methods

Proper maintenance of these cooling system components can prevent odors from invading your home:

  • Air Filter
    • Regular changing of your filter gets rid of contaminants in your air supply so they are not circulated back into the house. Changing your air filter regularly allows the filter to do its job, pulling odor-causing particles out of the air.
  • Evaporator Coils
    • Coils should be cleaned annually by an HVAC expert to eliminate built up debris. Mold and mildew can develop on dirty coils, restricting efficiency and causing odors indoors.
  • Ductwork
    • Proper cleaning of your ducts and vents eliminates accumulation of debris that cause odors over time.

If you are experiencing any of these strange smells, don’t hesitate to call Nelson Comfort and speak with a licensed, NATE-certified professional about the issues you face. We perform services for AC units to cut odors and improve cooling system efficiency!
