blog post bg

Does something in your house smell awry? Is it your air conditioner? If yes, you might want to eliminate the problem immediately to get clearer air in your house. When your air conditioner is not working efficiently during the summer, it is discomforting. On top of that, an air conditioner smelling terrible is never good for you and your family’s health.

In extreme cases, such problems need immediate attention. It is extremely important to fix such problems right away. You don’t need to worry about it all.

In this article, you will learn why your air conditioner smells, depending on the different types of odors. 

‘Rotten Eggs’ Smells

If your air conditioning system starts smelling like rotten eggs after turning on the system, it may probably be because of a dead insect or animal stuck inside the system. Most of the time, insects or rats get stuck in the system, and when they are dead, your system starts smelling like rotten eggs.

In such a case, calling out for an HVAC technician and getting your system cleaned is extremely important. Or else, the dead inside your system will be an open invitation for various diseases.

‘Dirty Socks’ Smells

Is your air conditioning unit smelling like dirty socks? It may be because of fungus and bacteria that are growing inside the system’s air ducts. You may also spot some dark green accumulation on the air duct pipes. This happens because the leftover water in the air ducts creates extra moisture in the unit. To prevent such problems, get your air conditioner cleaned by a trusted HVAC contractor.

‘Decomposed’ Smells

Does your air conditioning unit smell like something is decaying or decomposing? If yes, then it may be because of the problems associated with the drain ducts of the system. When the water cannot drain out of the system, the drain pipe accumulates, causing many fungus, bacteria, and germs. Hence, to avoid such problems, cleaning your air conditioning system from time to time can ensure a quality airflow in your home or office.


Now that you have properly understood the most common air conditioner odors, you can effectively discuss the solution with your HVAC Contractor. If you want to get an efficient and healthy airflow in your home or office, apart from checking out for such odors, you can also try listening to abnormal sounds from your air conditioning system.

If you experience any abnormal smell and noises, it may be an indication of a huge problem. If you smell something burning in or around your air conditioning system, immediately shut down the system. Call a well-trusted HVAC contractor to diagnose and fix the same.
