Client Testimonial

  • Residential Cleaning & Disinfection Services

    "Thanks again for the super professional service, your guys attitude and manners around my house and family were remarkable. I am not an easy customer but tonight I am surely a very happy one!"

  • Professional and Courteous Service

    Please thank your team for their hard work.

    They were professional and courteous and left the apartment cleaner than it was before! I look forward to contacting IAQ again for any aircon work!

    Thanks again.

  • The team just left about 10 minutes ago. Everything went very well- very professional. They were here early and had already checked in with the front office to get badges. Everything was left very clean after and they were very professional and efficient. I'm really happy- thank you.

  • I spoke with my husband who was here during the cleaning and he had nothing but good things to say about the your team!

    He said they arrived promptly and were very thorough from what he could see, both from inside the condo as well as going outside to the connecting unit. He was very impressed with their professionalism.

    Thank you very much !

  • A pest control product too

    Initially the first thing we noticed was those pesky mosquitoes suddenly disappeared from the office. We asked the makers if GermXit® had anything to do with this and found out that mosquitoes don't like Tea Tree Oil, it repeals them, so that was an added bonus. Clean air and no more mosquitoes.

  • Better than we thought !

    When we moved to a new office, everyone started to get sick. We asked for the air conditioners to be cleaned but that didn't seem to help. So we had GermXit® installed and hoped that would do the trick.  Over the next few months the sickness levels dropped and the staff started to comment that they hadn't had a cold or flu for a long time. Some of the staff have now bought GermXit® for their home too.

    Thanks GermXit®, it really works.

IAQ Technologies

Thailand’s first professional HVAC cleaning and disinfection service

IAQ Technologies is Thailand’s first professional HVAC cleaning and disinfection service.

We apply job-specific equipment for the most thorough and cost-effective HVAC cleaning and disinfection available anywhere in the world.

Mr. Carl Straub, an Australian, started the company in 1999. He was supported by Mr. Alistair MacMillan and Mr. Mark Ashton, the founders of Indoor Air Quality Technologies Pty. Ltd. of Melbourne. Mr. Robert Thein Pe, managing director of a major Thailand-based hotel chain, later joined IAQ Technologies Thailand as a director. Both companies have pioneered the practice of sophisticated HVAC cleaning and disinfection in Australia and Southeast Asia.

IAQ Technologies Work Methods

Our HVAC cleaning teams employ specialized equipment combined with high-volume negative pressure :

  • Air Knife
  • Negative Air Vaccum
  • Compressed air
  • Manual cleaning (Confined space work) – where needed

We will work with you to choose the method or combination of methods best suited to the job.

The best and most efficient cleaning method is by human hands. But if workers can’t fit inside a duct, the next best method is high-pressure compressed air.

Equipment and Fleet

Our custom-designed, high-pressure compressed air system can reach almost every single corner of any ductwork system.

We feed hoses into the ducts as far as 30 meters deep. We direct very high-pressure air through the ductwork with cleaning nozzles specially designed by IAQ. As the ductwork is scoured, a high-volume, negative-pressure vacuum pulls the dust and dirt out of the system.

A fleet of fully equipped service vehicles with Atlas Copco compressors are stringently controlled and maintained in excellent working order to prevent breakdowns and loss of valuable project time. Our equipment and methodology is recommended by NADCA. For more information please visit the NADCA website
