Most of the contaminates in a ductless air conditioner are not visible from the outside of the unit. This can be very confusing and you may not know if the cleaning has been performed effectively to the requirements of the ACWWA HVAC Wet Wash Guidelines For Ductless Split Systems.

Many of the specifications in the guide will not be practical for you to test when your cleaner arrives on site to perform the cleaning. However there are a few simple things you can do to ensure the guidelines are met.

1) Always choose an ACWWA Certified HVAC Wet Wash Specialist to perform the clean.

2) The covers MUST be removed to provide access to reach all the contaminates that must be cleaned to "As New" hygiene condition required in the guide. It is impossible to clean the condensate drains and other components if you don't have access. If your cleaner has not removed the covers then "As New" hygiene is simply not possible. 

3) Turn on the air conditioner and use a strong light to look into the outlet vents where the cold air comes out. You should clearly notice the difference before and after the clean. If you can still see the contaminates then the required "As New" hygiene specified in the guide has not been achieved,

4) Mould and other bio-contaminates that are simply "wetted" without being fully removed in the cleaning process, will simply return more aggressively usually within weeks. ACWWA Certified HVAC Wet Wash Specialists use professional grade equipment and processes to ensure all contaminates are removed from the entire unit to meet the "As New" hygiene requirement. You should always keep your Tax Invoice as a receipt and ask your cleaner for their warranty terms and conditions if this should occur.   

Although levels of usage and humidity can vary the pace of contaminate growth, a ductless air conditioner will always be more hygienic and efficient if it is returned to "As New" hygiene at least once every twelve months. Always consult with your ACWWA Certified HVAC Wet Wash Specialist and insist on an ACWWA Hygienically Cleaned Seal for your peace of mind that you have the best possible environment for healthy conditioned air.
