Air Duct Cleaning Questions
What is air duct cleaning?
Air duct cleaning removes dust, debris, allergens, and contaminants from your HVAC system using specialized equipment. This improves air quality, HVAC efficiency, and home cleanliness, ensuring a healthier living environment.
Cleaning your air ducts removes dust, allergens, and mold, improves airflow and HVAC efficiency, and reduces indoor air pollution. It helps prevent allergies, improves home cleanliness, and extends the life of your system.
The National Air Duct Cleaners Association (NADCA) recommends every 3-5 years. Homes with pets, allergies, smokers, or recent renovations may need cleaning more frequently.
Yes! Air duct cleaning improves air quality, reduces allergens, increases HVAC efficiency, and lowers energy bills by allowing your system to run more smoothly.
Signs include excessive dust buildup, musty odors, weak airflow, allergy flare-ups, or visible dirt in vents.
Yes! Our negative air cleaning process safely removes contaminants without damaging ducts or releasing debris into your home.
Air duct cleaning usually takes about 2 to 6 hours, depending on the size of your system and how dirty it is.
While you can do basic maintenance like changing filters, cleaning air ducts is best left to professionals who have the right tools and training. DIY cleaning only removes surface dust—professional cleaning fully extracts deep-set debris using specialized equipment.
To prepare for air duct cleaning, clear the area around vents and registers. This allows the technicians to do their job easily. We'll do the rest!

What's the difference between the basic and deep clean air duct cleanings?
Basic Clean (Agitation Cleaning) uses rotating brushes and compressed air to loosen dust and debris inside your ductwork. Ideal for light buildup or routine maintenance, but it does not fully remove contaminants.
Deep Clean (Negative Air Cleaning) uses powerful vacuum suction (negative air technology) to fully extract dust, allergens, and contaminants from the entire system. Ideal for homes with heavy dust buildup, allergies, or needing the most thorough clean.
If you want a surface-level refresh, choose Basic Clean. For maximum air quality and deep dust removal, go with Deep Clean.

Why is Mile High Ducts different from other air duct cleaning companies?
Mile High Ducts is local, family-owned,delivering honest, high-quality air duct cleaning with no hidden fees or gimmicks. Unlike competitors, we use negative air technology for a deeper, more effective clean and provide transparent pricing, before-and-after photos, and expert service to ensure your home's air is truly clean.
Other companies are offering $99 air duct cleaning services. Does Mile High Ducts offer this pricing?
Mile High Ducts doesn't offer $99 air duct cleaning because it's impossible to properly clean air ducts for $99.
Most $99 air duct cleaning offers are bait-and-switch scams. Companies advertise low prices but charge extra for essential services. Proper cleaning requires professional equipment, trained technicians, and time. $99 can't support these things.
Choose a trusted, certified company to ensure a thorough, honest cleaning without hidden fees. This link from the National Air Duct Cleaning Association (NADCA) shares how to avoid air duct cleaning scams.
