In the ACR2006 Standard, the National Air Duct Cleaner Association NADCA provides inspection criteria as well as a gravimetric analysis of dust known as the NADCA Test.
Benjel Consultant Chemists can conduct these tests for you in order to evaluate cleaning work and to verify the cleanliness of your ducts. On the other hand, if you collect samples on your own, we can provide you with the necessary material and support.
Our service is reliable, fast and the pricing low. A certificate will be given to you attesting that everything complies with the NADCA cleanliness criteria.
