Why Your Air Conditioner in Star City, AR, Stinks

An air conditioner that stinks isn’t pleasant, especially when you’re hoping for some cool refreshing air. Let’s track down some possible sources of that stinky smell that’s circulating throughout your vents in your Star City, AR, home.

Biological Growth

Dark, damp spaces like the evaporator coil and drain pan in your AC system are havens for biological growth. When these communities of microbes thrive, they can leave behind musty odors that waft through your home when your air conditioner runs and negatively impact indoor air quality.

Dirty Air Filter

Air filters clogged with dust and other airborne particles can cause the air you breathe to be dirtier than the air outside. In time, this buildup can turn into a veritable feast for bacteria and microbial growth, which is what you’re smelling. A dirty and obstructed filter blocks airflow and causes the system to work harder, possibly leading to odor problems.

Blocked Drain Line

Condensation that air conditioners generate drains off via a condensate line. If this line becomes clogged with algae or debris, the water backs up into the drain pan. Water that can’t escape provides a perfect environment for bacteria and other microbes to grow, giving off a sour or musty smell.

Animals Coming Inside

As unbelievable as it may seem, small critters such as rodents or insects will occasionally get into your ductwork or outdoor condenser unit. If they die inside, then decay will cause an atrocious rotting stench to move through your vents. This is certainly not a pleasant situation when it occurs.

Refrigerant Leaks

While it is less common, a refrigerant leak can sometimes result in an odor that smells sweet or smells like chemicals. The refrigerant doesn’t have a strong odor, but additives can create a noticeable scent. If you detect a sweet or strange chemical odor, it’s important to turn off your AC system and call a professional right away since refrigerant leaks can be dangerous.
