What should I do if there is a bad smell from my RV AC?Updated 2 months ago

A bad odor from your RV AC usually comes from dust, mold, or trapped moisture. Follow these steps to locate and fix the source:

• Check the air filter:

  • Remove and clean the filter.

  • If the smell persists even without the filter, move to the next step.

• Inspect the rooftop unit and drainage outlet:

  • Look for water buildup, mold, or debris such as insect or rodent remains.

  • Clean as needed.

• Professional cleaning:

  • If the odor continues, take your unit to a qualified repair store.

  • Some causes, like hidden mold or internal buildup, may not be visible but require professional cleaning.

Tip: Regular filter maintenance and checking for standing water can prevent most odors.
