What is Air Duct Cleaning?

Improve your indoor air quality and HVAC efficiency with professional air duct cleaning.

See FAQ for more information

Air duct cleaning is the process of removing dust, debris, allergens, and contaminants from your home’s HVAC system to improve air quality and efficiency. Using negative air pressure and HEPA-filtered vacuums, professional cleaning eliminates built-up dirt from ductwork, vents, and HVAC components. This process helps reduce allergens, improve airflow, and extend your HVAC system’s lifespan. Not only does clean ductwork improve air quality, but it can also prolong the life of your HVAC system, saving you money on repairs and energy costs in the long run.

Deep Cleaning | Negative Air Method

Our Deep Clean uses a negative air method to clean your air ducts. We use a high-powered vacuum system to create suction, fully extracting dust, debris, and contaminants from your ductwork while preventing them from re-entering your home. Unlike agitation cleaning, which only loosens debris, negative air ensures a deeper, more thorough clean for better air quality and HVAC efficiency. Ideal for homes with heavy dust buildup, allergy sufferers, or those wanting the most effective cleaning method.

<p>Our Basic Clean uses an agitation method to clean your air ducts. We use rotating brushes, air whips, and compressed air to loosen dust and debris from the duct walls. Unlike negative air cleaning, which fully extracts contaminants with powerful suction, agitation dislodges buildup but may not remove all particles as effectively. This method is a budget-friendly option for homes with light dust accumulation or for routine maintenance between deep cleanings.</p>

Why Mile High Ducts is Different

Let's face it. Air duct companies are hard to trust. Many are fly-by-night operations who use marketing and pricing gimmicks to win work. At Mile High Ducts, we pride ourselves on our commitment to our customers, honesty, and transparency.

We're local experts, not a national franchise

Our owner is born and raised in Colorado. We're a family-owned small business that knows the metro Denver market front to back.

Our pricing is honest & transparent

We don't use bait-and-switch pricing schemes. We're upfront about the costs and always match our customers with the right service.

We're professional, courteous, & clean

We show up on time. We treat your home like it's our own. We leave your home cleaner than when we arrived. We're HVAC and air duct cleaning experts.

We provide a superior clean

We don't believe in "blow and go" air duct cleaning that loosens but doesn’t fully remove debris. Mile High Ducts uses negative air technology for a thorough clean that removes debris.
