Spraying the AC

The short answer to whether or not you can spray your air conditioner to kill mold is: Yes. The long answer is a bit more complicated. It depends on what you use. Harsh chemicals in fungicides can harm its delicate evaporator and condenser coils. A mix of one cup of vinegar in a spray bottle filled with water makes for a good mold-killing solution that won't ruin your AC.

General Maintenance

Replace the filter after treating a mold problem in your air conditioning. Mold spores in the filter would just cycle back through the system otherwise. Regular cleaning or replacing the AC filter will help prevent mold from growing there in the first place.
