How to Kill Slime in an Air Conditioner
- 1). Turn off the air conditioner and switch off the breaker powering the unit at the main electrical panel.
- 2). Go to your air conditioning system in the attic or in a small closet. Look for the external drip pan -- it will have water inside it. If you do not see a drip pan, open the access panel on the unit with a screwdriver to expose the drip pan.
- 3). Put on rubber gloves. Carefully pull the drip pan out of the unit, if equipped with a removable drip pan, and dump the water out. If the drip pan is not removable, scoop the water out with a plastic cup.
- 4). Spray the evaporator coils liberally with an aerosol evaporator coil cleaner, then spray in and around the pan as well.
- 5). Thoroughly wipe the evaporator and the drip pan with a soft sponge to get the slime off the unit. Wipe away as much slime as possible, then reinsert the drip pan, if applicable.
- 6). Place two condensate pan tablets in the drip pan and allow to dissolve. The tablets will release an ingredient that prevents slime from forming.
- 7). Close the access door or fasten it back into place with a screwdriver. Turn the breaker on, then the air conditioner.
