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.

 
 

Benefits of Air Duct Sanitizer

Sanitizing kills harmful microorganisms that can grow in damp or dusty ductwork.

Removes Odor at the Source

Helps neutralize smells from pets, smoke, moisture, or previous occupants without perfumes or masking agents.

Improves Indoor Air Quality

Reduces airborne irritants and allergens, making the air cleaner and healthier to breathe.

Prevents Microbial Regrowth

Sanitizing helps inhibit future growth of bacteria, mold, and mildew inside your HVAC system.

Safe for Homes & Families

We use EnviroCON, an EPA-registered, low-toxicity disinfectant that’s safe for use around kids, pets, and sensitive individuals.

Enhances the Effectiveness of Air Duct Cleaning

When used after cleaning, sanitizer helps maintain a fresher, cleaner duct system longer.

Frequently asked questions about Air Duct Sanitizer

Is it safe for my family and pets?

Yes. We use EnviroCON®, an EPA-registered, low-toxicity sanitizer that’s safe for use around children, pets, and sensitive individuals.

Will it leave a strong chemical smell?

No. EnviroCON® has no perfumes or masking agents, and any light scent disappears quickly after application.

How long does the sanitizing process take?

The application itself takes about an hour as a part of an air duct cleaning service.

Do I need to leave the home during treatment?

No. The product is safe to apply in occupied spaces, and there's no need to vacate the home during or after service.

How long does it last?

While results vary, most sanitizing treatments help inhibit microbial growth for about year, especially when paired with routine duct maintenance.

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.

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!
