Why does the Air From my Air Conditioning Smell Bad?

  • Pet Odors: The number one cause of bad smells in the HVAC system is odors from pets. Over time, pet hair, pet dander, and even the ammonia from cats will absorb into the air ducts and cause the air passing through to perpetuate those smells throughout the home.Even pet odor that absorbs into the carpet will eventually find its way into the heating and air system. For those who have just moved into a new home, those smells may even be present from a previous owner. If you deal with pet allergies, it is time to call an air conditioner service.
  • Mold and Mildew: Living in Dallas or McKinney, TX means lots of humidity and while having the window or screen open for the summer breeze may seem pleasant, having it open for too long will invite moisture in to stay. It is recommended that residents in Dallas and McKinney, TX run their heating and air system at least one hour a day to avoid a buildup of moisture in the HVAC system.Not only will it allow mold and mildew to grow in the air ducts – causing a bad smell in the air – too much moisture built up in the air handler will strain the whole HVAC system and then you will truly need to call an AC service.If you are dealing with headaches, fatigue, and general malaise, you might be dealing with mold or mildew in your system.

  • Dust Mites and Other Dirt: For those who do not own pets, dust and dirt buildup in the heating and air system is the number one reason for bad smells. Dust and dirt is a reality of life we all have to deal with and it will inevitably accumulate in your HVAC. Fine dirt particles can actually float through the air and be caught up in the AC return.While the return filter will catch most of these particles, some still get through and clog the HVAC ducts. Dust does not always come from outside. In fact, it is most often generated from within the home by cooking and dead skin cells. This dust then attracts dust mites to infest the heating and air as well as other parts of the home.Over time, these dust mites die and dead ones will accumulate and decompose in the air ducts – resulting in bad smells to permeate the home. Additionally, these dust mites – while alive – can cause a wide range of health issues. Dust mites produce enzymes that are harmful to human cells. In most cases, this leads to ostensibly unexplained allergic reactions such as dermatitis, anaphylaxis, chronic pulmonary hypertension, and even pneumonia.
