5 Common A/C Smells and What They Mean

Having an air conditioning system that works is a necessity to ensure everyone's comfort during the hot summer months. Unfortunately, sometimes your HVAC system can end up creating pestering smells. Some of these smells can indicate a small problem, while others can indicate that you'll need to call an HVAC professional ASAP.

Dirty Socks Smell

If your home is starting to smell like dirty socks after you turn on your air conditioning system, then it's likely an indication that your evaporator coils need to be cleaned. Over time, the evaporator coils in your HVAC system can develop microbial growth that can make your whole home smell like it's laundry day. When you're smelling this odor, it's time to call in an HVAC professional to clean your evaporator coils. Continuing to run your HVAC system until an HVAC expert arrives won't harm your system, but it may offend your nose.

Exhaust Fumes Smell

When you start to smell exhaust fumes while in your home, it can be an indication that there is a fluid leak in your air conditioning system. In most cases, the fluid is leaking on a warm part of your air conditioning system, which is causing the fluid to steam. In this type of situation, it's best to contact an HVAC professional to evaluate your HVAC system. It's not advisable to run your air conditioning until an HVAC professional takes a look at it.

Gunpowder Smell

A pungent smell that your HVAC system may produce is gun powder. Some people refer to this smell as fire or something burning. If you notice this distinctive smell in your home, you should turn off your HVAC air conditioning system. It's likely that there is a problem with an overheated part or frayed wiring in your HVAC system. Check the HVAC system for any fire and call the fire department if you find one. You should have an HVAC professional evaluate your air conditioning system before turning it back on.

Trash Smell

No one likes to smell trash in their home. If you do, and it's not because the trash is full, it could be your HVAC system. You'll likely notice this smell when you first turn on your air conditioning system. In most cases, this is likely a dead animal that is trapped within your HVAC system. It's not uncommon for animals to seek shelter in your HVAC system over the winter months. In this situation, it's best to call in an HVAC professional to evaluate your entire HVAC system before turning the air conditioning back on.

Mold or Mildew Smell

The last smell that we're going to cover in our HVAC smells list is that of mold or mildew when you're running your air conditioning system. Due to the nature of air conditioning systems, it's not uncommon for mold to develop throughout your HVAC system. If you smell mold or mildew, it's best to shut your air conditioning off and contact an HVAC professional. The HVAC professional will be able to look over your HVAC system, identify where the mold is growing, and remove it. You never want to let this HVAC smell go, as mold spores can be harmful to your respiratory health as they continue to be circulated by your HVAC system.
