What Our Clients Say About Us

We are always honored when our customers take their time to share
their experience with Guarantee.


Nancy P. Walter Manager – AAA Headquarters in Bend, OR

“Having our office ducts cleaned with the RamAir system was a very positive experience… no dust escaped into the building during the cleaning, and we’ve noticed an extraordinary difference in our air-quality.“


Jace Baldosser General Manager, Blue Lake Casino

“It was a pleasure working with David and his crew. They knocked the job out of the park, and I would be happy to recommend them to anyone in need of their services.”


Drew Bledsoe NFL Quarterback Legend

“Great Job! We had our ducts cleaned by Guarantee Duct Cleaning while away on vacation in Mexico. Upon returning home, I immediately noticed how much cleaner the air in the home was! Thank you for doing such a great job!”


Daniel Miller HVAC Lead Tech at the Fresno Penitentiary

“Guarantee Commercial Air Duct Cleaning cleaned the HVAC system in our entire prison in a fraction of the time and at 1/3 the cost of the company we almost hired. The prison is saving tens of thousands of dollars in cooling costs per month because the systems run so much more efficiently after the cleaning.”


Ryan Marr Homeowner

“A truly professional experience! The tools and technology used allowed for a thorough dryer vent cleaning while keeping the house and surrounding area clean. The owner was super professional and knowledgeable about the process and even shared how his proprietary tools worked. He was professional, knowledgeable, and friendly. I would highly recommend their services and look forward to working with them again.”


Brenda Gessner Building Systems Coordinator, ODOT

“Having to coordinate with so many vendors, it’s refreshing to work with Guarantee Air Duct Cleaning. They are very accommodating, they always show up on time, their pricing is fair, and they do a great job. They’ve cleaned the HVAC systems in several of our buildings, we’ve noticed a substantial decrease in dust and particulate in the buildings, and the filters are staying much cleaner for considerably longer. We will absolutely continue to use them for all our HVAC duct cleaning needs.”
