Professional Air Duct Sanitizer in Denver, CO
Eliminate odors, mold, and bacteria from your HVAC system with safe, effective air duct sanitizing.
What is air duct sanitizer?
A safe, effective way to eliminate odors, bacteria, and mold from inside your HVAC system.
Air duct sanitizer is a specialized treatment applied inside your HVAC system to eliminate bacteria, mold, mildew, and lingering odors caused by moisture, pets, smoke, or everyday living. At Mile High Ducts, we use EnviroCON®, an EPA-registered, low-toxicity disinfectant that’s safe for homes with children, pets, and sensitive individuals.
Applied after a professional duct cleaning, it helps maintain cleaner, fresher indoor air and reduces the risk of microbial growth inside your vents - without harsh chemicals or strong odors.

Real stories from our amazing customers.
Andrew is always professional, relaxed, and provides detailed feedback of work done and welcomes any and all questions. I will continue to refer this business.
Andrew and Jeff did a great job, and really understand the technical aspects of how HVAC works. They cleaned out out our entire system and problem solved a tricky issue with the dryer vent, to boot! Very friendly. I recommend them for everyone needing a cleanout of their ducts.
Andrew and Jeff did a great job cleaning out our ducts using negative air pressure. We had to cancel twice due to snowstorms, but they were on time and conscience of moving in and out of the house with their shoes. They completed the work in 3.5 hours.
Andy was courteous, prompt, professional, and was very careful and clean in our house. The things he shared indicated a very experienced and knowledgeable individual. I highly recommend him.
We had a fantastic experience with this air duct cleaning service! Andrew was the technician who handled the job, and he did an outstanding job from start to finish. He honored the original estimate, thoroughly cleaned our air ducts, and took the time to explain the entire process in detail. Throughout the cleaning, he showed us the results, which gave us confidence in the quality of the work. He also did a great job cleaning the dryer duct. We highly recommend Andrew for his professionalism, expertise, and attention to detail!
Excellent work. My vents are so clean I could eat off of them. Professional and clean and respectful of your home.
Great job! Easy to set up an appointment and everyone was super professional
Andrew was great!! He went above and beyond what was expected. As an added bonus, he’s very friendly and courteous. I highly recommend!
Andrew is very knowledgeable and was so helpful in determining the right approach for our situation. You’re not only paying for a service but for his level of expertise. He’s now our go-to guy for any vent or duct cleaning.
If you are looking for a reliable and honest company, you have found it. Our house presented it's own challenges disclosed before hand, but Andrew and Able delivered exception service and honored the estimated price. They were very thorough and left the house immaculate. They won't sell you on a service you don't need and help explain what will work best for your house and specific zones. Highly recommend!
