Here's some of our recent commercial client testimonials:

“Guarantee Air Duct Cleaning was extremely flexible with scheduling and very accommodating.  They understood the need to have minimal impact on the daily operations of the Casino.  The professionals aggressively addressed any safety concerns and adjusted accordingly.  They will definitely be our first contact when we schedule duct cleaning in the future.”

Cloves Tennis | Facilities Director | Tribal Casinos

“Our staff and patients have commented that they don’t feel “stuffed up” like they did before the cleaning, and the air feels so much cleaner and healthier. The furniture, countertops and equipment in the facility are not accumulating dust like they were before the service. I was very impressed with the team’s friendly professionalism, they were a delight with whom to work, and I was very pleased that they could come in after hours on a Sunday to perform the service. We’ll be using them again in the future.
