RV Air Conditioner Smells Like Rotten Eggs

My RV air conditioner smells like rotten eggs. This sounds so familiar, not? The discussion over RV air conditioner reeks has taken over hypes nowadays. People are scrolling through forums and blog posts to figure out a permanent cure. But unfortunately, nothing appears to be helpful.

A rotten egg smell is seriously a filthy stench to get rid of. Once it starts piling up in your trailer, there will be no corners left with a fresh fragrance.

It has the potential to make chambers so stagnant that you will face difficulty disposing of the unyielding bad smell with each passing day. 

The unpleasant smell might emerge from a number of things that your RV has in store for a long period of time.

Even stagnant water, exhaust fumes, or gas leaks could act as a leading cause. And guessing upon the root cause isn’t going to offer any solutions. You need to ensure diagnosing the problem first. 

What Causes Bad RV Air Conditioner Smells?

An unpleasant odor such as rotten egg odor forges a nauseating atmosphere in your RV. Especially when someone just gets inside the trailer outdoors, the stench becomes much denser.

But does a rotten egg left in the dump for days have any connection to air conditioners to produce such a foul smell? Of course, not. 

One of the main reasons your RV air conditioner smells like rotten eggs is that it has a leakage somewhere in the air ducts. You might wonder whether the natural gas leak is supposed to produce smells.

They are not, but manufacturers tend to add a small amount of sulfur inside. That way, it alerts everyone of leak damage immediately. 

When your RV AC is not keeping up with proper ventilation, it can also cause a foul smell. Without proper airflow through the compartments, the system will create a stale area inside, causing rotten egg smells to spread all over the trailer.

Another leading cause can be a mold buildup inside your AC compartments. When the AC remains unemployed during winter, the dusty air gets trapped inside the unit.

The longer it stays there, the more mold growth it causes to the compressor and condenser coils. And that translates into a moldy smell of rotten eggs later on. 

Rotten eggs smell can also be produced from a faulty air filter. An air filter’s primary purpose is to pull out the bad smell from the circulated air vents. So, when you get a dirty air filter, it fails to operate the entire air filtration process, causing bad odor to outspread through the AC compartments.

How Do You Fix A Smelly Air Conditioner

Air conditioner smells are somewhat a luxury while still a necessity. You cannot expect an AC to circulate a rotten egg smell in the presence of your guests. Then again, it is not supposed to cause you discomfort even when you are spending lonesome time. 

Either way, you need to make sure to fix your smelly air conditioner as soon as possible. As mentioned earlier, you must diagnose the main root of the problem first. Then you’ll know exactly which strategy to use for the repair. Below mentioned are some vital factors to consider while repairing a smelly air conditioner. 

Change Air Filters 

Check whether your air filter is dirty. A faulty or dirty air filter is the leading cause for rotten eggs smell in your RV. You must change the air filter periodically every 30 to 60 days.

Clean Evaporators Coils

Evaporator coils are another source of rotten egg smells. So, make sure to check on them and clean them frequently with a foaming coil cleaner agent. 

Clean Condensate Lines

Every AC system features a drain line near its outer unit. Its job is to drip out the excess water inside the air vents. When you see colored water draining, it’s time you clean it with a water solution.

This segment essentially covers some common queries regarding smelly RV conditioners that might be of your help,

Is it OK to spray water on your air conditioner?

Why does my RV smell like eggs?

Chemical reactions create such RV bad odor. When there are bacteria in the water, anodes reacting with water to make hydrogen sulfide, or when an overcharged battery releases hydrogen sulfide gas, it is more likely to produce such filthy stench.

How To Get Rid Of Nasty Odors?

An RV musty odor can make your new home feel old and smelly. Luckily, there are a few ways you can combat these smells, including running a dehumidifier to remove excess moisture in the air. For an extra fresh scent, use Febreze Air; it’s like having your own air freshener built into the ceiling of your RV.

Closing Thoughts

If your RV smells like a rotten egg, you must fix it as quickly as possible. The first step is to use the information above to determine where the stench originates from. Once you’ve identified the source, you can hire someone to do further repairs and stop the odor before it becomes worse.

Ignoring the smell your air conditioning unit emits is unwise. It may not appear to be a primary concern, yet neglecting it could exacerbate a problem.

Many people think that cleaning their AC unit’s exterior will improve its performance, but this doesn’t help.

The best way to combat the problems with your A/C unit is to keep it clean on the inside. You should remove dust and dirt from the coils to help your AC run more efficiently.

Take care of your vehicle, and it will take care of you. If you keep up on maintenance and make regular trips to your mechanic, you’ll be on the road in no time.
