Five Common A/C Smells and What They Mean

Having air conditioning in the summertime is a must to ensure your family stays comfortable. However, if you start to smell something funky when your air conditioner is turned on or has been running for a while, it can be discouraging. Knowing what to do to solve the smell starts with determining the type of smell it is.

Dirty Socks Smell

One of the most common air conditioning smells that HVAC professionals get called for is that of dirty socks. This type of HVAC smell tends to reach throughout your entire HVAC system and home. In most cases, this smell is simply a result of dirty evaporator coils in your HVAC system. Over time, these evaporator coils can attract unwanted microbial growth. If you're experiencing this smell, you'll need to contact an HVAC professional to clean the evaporator coils on your air conditioning unit. It's okay to run your air conditioning system while you're waiting on your HVAC professional to show up.

Exhaust Fumes Smell

Another common smell that most homeowners with an HVAC air conditioning system can easily recognize is that of exhaust fumes. The likely cause of this smell is a fluid in your HVAC system leaking on a warm component of your air conditioning unit. The fluid is getting evaporated and creating an unpleasant odor from your HVAC system. In this scenario, it's best to turn your air conditioning unit completely off and call in an HVAC professional to evaluate your HVAC issue.

Garbage Smell

The distinct smell of garbage can throw you off when it comes to starting up your air conditioning system. If you notice this smell with your HVAC system, it's likely a dead animal. Over the winter months, creatures can crawl into your HVAC system for heat. Unfortunately, this can lead to a nasty smell when you go to start up your air conditioning system in the summertime. It's best to turn your air conditioning unit back off and contact an HVAC professional to clean your HVAC system.

Mold Smell

The smell of mold or mildew throughout your home can mean that your air conditioning unit has mildew growth inside its ductwork. Due to the nature of removing humidity from the air, this naturally happens over time. Since mold spores can be dangerous to inhale, it's best to turn your HVAC air conditioning system off. You'll want to call in an HVAC professional to come and clean your HVAC system. Your HVAC professional will be able to identify just where the mold is growing in your HVAC system, remove it, and can provide advice to help prevent more growth in the future.

Burning Smell

One of the most alarming HVAC smells that you may pick up from your HVAC air conditioning system is a burning one. When you smell something burning, it's best to turn the entire HVAC unit off. Check for a fire or smoke as you may have a fire in your air conditioning system. The likely cause of this smell is going to be frayed wires or overheated mechanical parts. It's best to leave your air conditioning system off until you have it evaluated by an HVAC professional.
