Patent Cleaning Process - DUCTZ Indoor Air Professionals

Our Patented Process

As a brief overview, our process involves any number of 127 identifiable and distinct tasks. It demands an array of tools, machinery, and supplies. And, it includes our exclusive patented process, which involves the application of a metallic barrier in the air handler, eliminating fiberglass shedding and preventing the fiberglass from acting like an absorbent sponge, which collects dirt and moisture and creates a breeding ground for mold, bacteria, and fungi. Our technicians are trained in the complete step-by-step process, gaining a full understanding of not only how we clean to this high standard, but also why.

Scam Alert!

The EPA and The National Air Duct Cleaners Association (NADCA) define the term “duct cleaning” or “HVAC system cleaning” as cleaning the entire system. “The entire system” is the A/C or furnace unit, main trunk lines that connect to that unit, and all branch runs from the main trunk. NADCA defines the “system to be cleaned” as any internal surface which air moves across. Therefore, any company you contract with must be able to prove their method of cleaning complies with the EPA and NADCA guidelines.

Based upon our survey of over 20 former employees of several companies offering duct cleaning services starting under $10 a vent, most said that the customers felt that if the registers were cleaned and some sort of specialized duct cleaning machine was used, the job was performed properly. But when questioned further, not one former employee could make the claim that the entire air conditioning system was cleaned and most admitted that they personally felt they had taken advantage of the customer because they knew dirt and debris remained in the system after cleaning.

Listed below are some other facts that were uncovered during our survey of these companies’ former employees:

  • None of the companies offer a product that allows comparison to a full duct cleaning job. Main duct work trunk lines are not included in their initial price for cleaning. When the system unit is included, it is unclear as to what will be cleaned. Various companies will do portions of your system unit to be able to say it has been cleaned and increase the perceived value.
  • All technicians had to upsell the customer after beginning the job since a large part of their salary was based on commissions. The company pays up to 40% commissions on any additional work or products sold after the job begins.
  • After extensive testing and analysis at our residential duct cleaning training center, the equipment commonly used by low price competitors has been found to be ineffective after the first 10 feet of duct work. Therefore, if you want more than 10 feet of your duct work cleaned, you must select a different method of cleaning.
  • The equipment was also proven ineffective on round, flexible or metal duct greater than 12 in diameter.
  • The technicians were aware that the specialized equipment they were given was not capable of cleaning square fiberglass duct work. During our test of this equipment, duct board fiberglass duct systems were damaged during the cleaning process, which would allow fiberglass particles to enter the living environment after the system was re-energized. On any square or rectangular duct, a round brushing system is ineffective in the corners of the duct work, leaving debris behind.
  • After hiring several of these employees, and assessing their cleaning techniques, the results indicated that little to no training had been given to them to indicate what level of cleanliness should be achieved. Many of them had never been told that the entire system should be cleaned.
  • The employees of these companies honestly feel they are performing the work correctly because they have been given no other information.
  • Four employees who were hired and sent for retraining quit within one month of learning the accepted standard of cleaning. During their exit survey, almost all cited that the accepted standard for cleaning was too much work compared to the way that they were doing it at the previous company.
  • Low-cost companies are very rarely based in the town they have the phone numbers listed for. Some are out of the county and quite a few reside in another state completely.
  • Special emphasis is given to the theatrics of the job and much attention is paid to things that only you, the customer, will see. Being that 90% of the heating/cooling system and duct work is hidden from your view, the main focus is to clean only what you are aware of.
  • Of the employees surveyed, only 10% had any formal training in the HVAC industry. Most responded that the customer was told to contact another company when their cooling unit or furnace failed to restart after the cleaning process. Many times this would leave the customer without air conditioning or heat.

From Yelp

As someone who suffers from indoor allergies, I have to be careful with pollen, dust, and mold, or else I launch into a huge sneezing fit. I could see the crud building up on the air conditioning coils every time that I changed the filter and knew that it was time to get someone in here to clean the whole air conditioning system.

I found the guys from Ductz through an online search, and had one of their reps come out to inspect the system. As expected he recommended a cleaning of the air conditioning coil, the blower fan, the ductwork and registers, and the entire clothes dryer vent system. I knew it wasn’t going to be cheap, especially after he showed me all of the crap that had been building up in the vents over the years.

The guys spent about two hours, vacuuming, scrubbing, and resealing the ductwork, and then washing all of the rust and crud off of the blower fan. Then finally they got up on a ladder and vacuumed out the length of the dryer vent from outside. I don’t wanna know how much junk they washed away, since the previous owner of this condo had two large sheep dogs who shed all over the place.

I can see an immediate improvement of both the efficiency of the air conditioning and the clothes dryer, so it was clearly worth the expense. Plus the long-term health benefits are a good thing.

These guys do an excellent job, and they’re very good about covering all of the furniture before they start on the job. They also vacummed and cleaned up before they wrapped up my job. Excellent customer service!

Excellent service, workers and prices. I won’t work with another company again! I am extremely happy with how the service tech cleaned out my dryer vent duct last week, my dryer hasn’t worked that well ever. I had a roof shingle clogging it up and I had bought that dryer after my new roof was installed. Scheduling an appointment with my work schedule is tough but Joan was very flexible with me. And the cost was the lowest around, I called everywhere and this was the best pricing in the industry. I will be having my entire house done after the New Year. Thanks Ductz of Chattanooga!
