Car aircon smells like rotten eggs - what could be the issue?

Bacteria can thrive in moist environments, like air conditioning systems. If filters are not maintained, it leads to smells and potential health hazards.

Just check your air filter! I learned that a dirty air filter might not directly cause that smell, but it can worsen air quality in your car. Keep it clean!

Great advice! Filters play a crucial role in keeping your car air fresh. Don’t underestimate a good maintenance routine!

If all else fails and it still smells, consider entertaining yourself on those long drives by imagining you’re in a smelly swamp! Just kidding, but seriously, get it checked out!

I think a rotten egg smell often indicates sulfur bacteria in the AC system. It could also be a sign of a clogged drain. Cleaning the evaporator core might help!

That sounds plausible! Suggested cleaning methods, like using an AC cleaner spray, could be a good first step.

Make sure to run your AC system on high for a few minutes after cleaning to help dry out the moisture. That can help prevent bacteria growth too!

Great tip! Moisture really is the enemy here. Regular maintenance checks can also be beneficial.

I agree with you, but if the smell persists, it might be best to see a professional. They can check for any underlying issues in the system.

Totally! I once ignored a similar smell, and it turned out to be a dead rodent in my vents—yikes!

To prevent future issues, consider using an air filter designed to prevent odors. It’s a small investment for peace of mind.

Good idea! I’ve also heard that leaving windows cracked slightly when parked can help reduce moisture buildup.

What’s the most common cause for this smell? Is it just bacteria, or could other factors play a role?

From what I’ve read, bacteria is a culprit, but leaks and mold can also contribute. It’s a tricky issue!

I once tried a home remedy of vinegar and water to clean the system—it actually worked! But remember, if it smells like rotten eggs, don’t ignore it!
