Is Duct Cleaning Right For Your HVAC Company?

Snipsmag Duct Cleaning Disinfectant Application interviewed David Hart in July of 2020. David Hart explains his history in the industry and the effectiveness of his methods.

From the article:

“I have been involved with the HVAC cleaning industry for nearly 30 years. Upon completion of my military service, I moved back to Oregon and took a job at a carpet cleaning company. The company also offered “duct cleaning” (in quotes because it was simply sticking the carpet cleaning vacuum hose into the ducts to suck up some of the loose debris) as an additional service. As far as the customer was concerned, I was a professional duct cleaner.

In 1998, I launched Guarantee Carpet Cleaning in Bend, Oregon. I fared very well, soon dominating the local industry. As public interest for indoor air quality became more prevalent, my customers regularly approached me, asking if I provided duct cleaning or if I could recommend somebody who did. This further renewed my interest in adding duct cleaning to my service menu.

The available options were cumbersome, expensive, ineffective and had the potential for damaging the ducts. I knew there had to be a better way, and there was, of course.

The Wow Factor

Duct cleaning isn’t rocket science, it’s basically turning dirty tubes into clean tubes. However, a duct cleaning system absolutely needs airflow. I chose to harness the power of the air mover that’s already mounted in every building — the air handler.

Finally, to supply the visual “wow factor,” I designed a clear, polycarbonate box through which all the dust and debris would pass as it stormed out of the duct system and into the HEPA vacuum. As a final touch, to showcase the debris being removed, LED lights were added. My customers, both residential and commercial, absolutely loved the results. Referrals for duct cleaning began pouring in.

Guarantee Cleaning Services is now focused solely on duct cleaning. This system is used in residential, commercial, disaster, forensic restoration and even meth decontamination.

As for the system I designed, it is now being used in every major city in the United States and 21 foreign countries. This system is used to clean ducts in homes, businesses, skyscrapers, hospitals, shopping malls… all types of buildings including state prisons.

With the demand for duct cleaning is skyrocketing, it’s time for you to think about how you can add duct cleaning to your HVAC business as a service.

COVID-19 & Dirty Ducts

Surely, you’re joking. Add another service to my HVAC business during a pandemic?

The truth is, it has always been a great time to add duct cleaning to your existing HVAC contracting business. But now is the perfect time. Our global population has never been more motivated to clean their homes, businesses, and ask about indoor air quality. As a result, the demand for HVAC duct cleaning is going absolutely gangbusters, launching the industry to unprecedented heights. Although this new demand has only just started, rest assure that this new demand for duct cleaning is only the beginning.

As of the writing of this article, it has only been a few months since the coronavirus pandemic has completely stopped the world. Up until the day of that announcement, nobody gave a second thought about shaking hands with anybody and everybody they met; we packed entertainment venues and public transportation; we even crammed together like sardines to enjoy concerts and had a blast while doing it.

Fast forward to today. Right now, you’ll get a dirty look at the mini-mart if you stand five (instead of a good, solid six) feet away from someone. Heaven forbid you attempt to shake somebody’s hand. Only the bravest even dare to bump elbows in lieu of a handshake. We’ve officially been conditioned.”
