David Chen is excited to announce that he has been awarded NSW Franchisee for 2018/2019 and also proudly accepts the Sanitair Customer Service Award for the Year.

David wishes to extend a heartfelt THANK YOU to all the Sanitair customers who welcomed Sanitair Chatswood into their homes and businesses over the past 12 months. It has been Sanitair’s absolute pleasure to provide fresh, clean, bacteria free air to each and every one of you and we are dedicated to ensuring your systems operate efficiently and continue to remain free of mould and bacteria.
I have lived in Sydney for the past 15 years and love where I live.  Australia has provided myself and my family with so many opportunities. I work with the philosophy of ensuring my clients interests are the highest priority.  I believe that by providing customers with better service the result will be happier clients.  I put this belief into my daily practice and I am never afraid to go the extra mile to give all my clients the utmost in satisfaction.
Prior to joining Sanitair I worked in the education industry.  To be exceptional at my work I have had to work hard on self adaption and learn new skills in order to achieve more independence.

A friendly team that clearly explained what they were doing, and took the time to do a thorough job. I hadn't realised how important it was to get my air-conditioner cleaned until I saw the results. Recommend!
