“I wanted to thank you for doing such a wonderful job cleaning and sanitizing the vent system in our home. I researched the different companies in St Louis for over three months to find the company that would do the BEST job for the best price. After much research, National Air Duct Cleaning Corp had the best record for customer satisfaction and gave me the most accurate price quote of all 5 companies. They were the only company that insisted on giving me an in-home quote rather than quoting me a low price over the phone. According to neighbors I spoke with, other companies quoted them a low price so they could get into the home and then increased the price in the middle of the cleaning project and once the cleaning has started you don’t really have any options but to pay the difference. We really appreciated your honesty and integrity. We will definitely be referring our friends and neighbors…….”

“This is to inform you of the great service we received from National Air Duct Cleaning Corp. Our facility is unique in that we regularly house over 200 animals at one time. We have a large amount of fur and dander that gets into our ductwork and its imperative that we keep the airflow clean and disease free. The guys were thorough and professional. They were able to work around our public hours to allow no disruption for our customers. They were polite and easy to work with. I will use National Air Duct Cleaning Corp for our future duct cleaning needs, and would recommend them to any business that is in need of cleaning.”

“This letter of recommendation is offered of our voluntary will and is not solicited. Our church contracted with Dan Morter to clean the extensive supply and return ductwork in or educational building and for the two furnace systems with their associated ductwork. The work was completed in a workmanship manner and the cleanup was also excellent.
We have no reservation in recommending Dan Morter and his able cleaning crews to anyone wanting a good job and clean ducts when they are finished. I welcome any calls from interested parties and will gladly give a tour of our facilities so the cleaned ductwork can be viewed. “

“I wanted to express my sincere gratitude for the wonderful experience you provided to the Healing Arts Center.
When I initially began researching companies to clean the air ducts on the second level of the building that houses my office.  I did not expect to be met with such kindness, prompt service, and attention to detail.  Most companies just wanted to give me a general quote over the phone without even visiting the space.  The fact that you took the time to discuss the options over the phone and spent a substantial amount of time on site explaining the details of each option, truly impressed me.  And, when you were able to schedule the time to conduct the work within a few days, I was even more impressed.  However, the true testament came when I returned to my office after the work was done….I could not even tell your company had been there because my office was left in pristine condition!  Since the work was completed, I have been able to notice a complete difference in the air quality, especially since your company uses eco friendly products.
Thank you again for the wonderful experience you provided to the Healing Arts Center.“
