HVAC, Innovation, and Industry Growth

David Hart discusses HVAC cleaning, indoor air quality, and best practices for restorers

On this episode of TradeTalks: Unlocking The Experience, we’re joined by David Hart, Founder/CEO of RamAir International, Inc, Owner of Guarantee Air Ducts Cleaning, Inc, and Owner of Guarantee Biohazard Remediation, Inc.

After David finished his stint with the army in the early 1990s, he started working for a carpet cleaning company that also did air duct cleaning, which eventually led him to becoming the lead technician, from there, the rest is history. If you couldn’t tell, David has fully embraced every aspect of our industry, and that passion inspired him to speak about HVAC at this year’s event.

Listen on the go!

Key highlights of this episode include:

What led David to start his own HVAC company and develop innovative HVAC cleaning methods.
David shares why HVAC plays such an important role in the restoration and cleaning industries. HVAC systems directly affect indoor air quality in every building, yet many professionals still overlook them.
After attending David’s session, attendees will understand why they should treat HVAC as part of every restoration scope. David explains why proper cleaning and decontamination methods matter, especially in biohazard situations, and why professionals rely on positive air methods.
David mentioned that The Experience is the “Adult Disneyland” for our industry. You get the latest equipment, meet industry experts, learn, and have endless networking opportunities.
Fun fact: David describes himself as a science and technology enthusiast who enjoys exploring data, research and technical details. He spends months, and sometimes years, developing major papers and standards, and that process continues to motivate him.

David will be joined by John Miles, a technical expert in flexible duct development who brings specialized expertise in adhesive manufacturing and base polymer chemistry. Together, they will present at The Experience on Wednesday, September 9, from 9:40 – 10:10 a.m. To learn more about their session, check out the agenda.

We look forward to seeing you at the Paris Hotel & Casino in Las Vegas, NV from September 9 -11, 2026. To register and learn more about the event, click here.
