Aircon Cleaning FAQ

The indoor air conditioner unit has air filters that need regular cleaning. Australia manufacturers usually recommend that you clean the filters every few weeks, but it really depends how often you use the air conditioner. Simply put, the more you use it, the more often you should clean the filters.

There are also times when power might go off abruptly meaning they have to wait for it to continue working which might also take some time. General aircon servicing usually take 20 – 30 minutes per unit, chemical cleaning at about 30 minutes per unit and aircon chemical overhaul takes about 1 hour per unit.

Mix up your cleaning solution. In the spray bottle, combine 2 cups of water, a cup of bleach and 4 drops of liquid dish detergent. Remove the air filter, remove the A/C unit grill, spray the interior with the mold-killing spray, wipe out the interior of the unit, scrub the grill and put the air conditioner back together.

To clean a split air conditioner, place an aircon bag, which can be purchased online, around the bottom part of the AC to catch runoff. Once in position, you can spray coil cleaning spray onto the cooling fins’ surface, rotary blades, and coils. For the best clean, leave the spray on for 10-20 minutes.

Find and remove your air conditioner’s condensation drain line. Flush the line with bleach and hot water, or with undiluted distilled white vinegar if you don’t want to use bleach to kill any fungi, mold or mildew that may be in the line. Allow the line to dry.

Take your spray bottle, vinegar and water. Mix ½ water and ½ vinegar inside the bottle. Shake the solution well, and apply it to the evaporator coil and condenser coil. Vinegar will not harm the parts and is a very effective cleaner.

Air conditioning sickness starts where air conditioners and bacteria, fungi, mold, and mildew meet. If your home or office is a breeding ground for mold and bacteria growth or a regularly unvacuumed space, an air conditioner will only circulate the sickness-inducing allergens that are already present.

When Auto clean is enabled, the indoor air blower works at full speed for a few minutes so that any moisture within the indoor unit gets blown away or get evaporated. Using the Auto clean feature once every few days will help in preventing rusting of the evaporator coil and growth of harmful microorganisms within the AC.

Maintain the drain pans. If the drain pans are not sloped and cleaned regularly, standing water won’t be able to drain through the deep seal trap and will accumulate in the drain pans. Replace air filters regularly, apply an HVAC mold inhibitor, use a disinfectant, keep ducts dry and check the air intakes.
