What Your Air Conditioner Smells Mean
There’s nothing better than stepping outside in the spring and summer to take in some fresh air and enjoy the beautiful weather. That lovely ambiance can be ruined, though, if there is a pungent smell coming from your air conditioner. If you know there’s not a family of skunks living under your deck and discover it truly is your AC that smells, you’ll want to figure out why.
There are many reasons your air conditioner may stink – some indicating a more pressing issue than others. These are the most common AC smell complaints we receive from customers, but this list isn’t exhaustive. We’ve heard it all from crayons to glue and more!
Smells like feet
An air conditioner that smells like feet indicates that it is holding water. Water can collect in the unit if it is not draining properly. A cleaning that is part of a regular air conditioner tune up should solve the issue of your dirty AC and allow the water to be released. If it is an ongoing issue then you may need to have further diagnostics run on your AC unit to determine why the water isn’t draining well.
Smells like burning
If your air conditioner smells like burning and the smell lasts for more than 30 minutes it usually indicates a mechanical or wiring issue. These can be serious so you should shut off the unit and call for AC repair immediately. If you only smell burning when you first turn it on for the year and the smell dissipates, then there is nothing to worry about as this is completely normal.
Smells like rotten eggs
If your air conditioner smells like rotten eggs this typically indicates a dead animal in the air ducts. Unfortunately critters can sometimes sneak in from the outside to seek shelter in the ductwork. You should call for duct cleaning and make sure to get a deodorizer/sanitation treatment included with the project. Ask the duct cleaning company to utilize a camera to check out if your suspicions are confirmed before they get started.
Alternatively, if it is not a dead animal it could also be the more serious problem of a gas leak. The odors from a gas leak and decomposing animal are slightly different and sometimes hard to distinguish. If you suspect it may actually be a gas leak or are unsure, call your gas supplier first to check for leaks. This is important for the safety of your family.
Smells like mildew
If your air conditioner smells like mildew then mold may be growing inside the unit. ACs work to remove heat and moisture from the home, so when this moisture doesn’t drain properly, mold can grow. A dirty filter could also be the cause. If you do discover mold inside your air conditioner it is best to call for HVAC repair. They can determine whether or not the moldy parts of the AC can be salvaged and recommend some indoor air quality solutions to prevent any future mold growth.
Smells like gunpowder
If your air conditioner smells like gunpowder, it typically points to a fried fan motor or circuit board. This smell is caused from these components actually overheating and burning inside the system. If you have a persistent gunpowder smell coming from the unit, turn off the AC and call for professional repair.
Smells like exhaust fumes
If your air conditioner smells like exhaust fumes you probably have a fluid leak. There are many various fluids inside the AC that ensure all the parts and pieces operate properly. If you do smell exhaust from your air conditioner it is best to shut it off and call for AC repair.
