Why Air Duct Cleaning Matters

The EPA estimates that indoor air can be 2 to 5 times more polluted than outdoor air. Your HVAC ducts circulate air throughout your home 5 to 7 times per day — carrying dust, allergens, pet dander, mold spores, and bacteria along with it.

Regular duct cleaning reduces allergens, eliminates musty odors, improves HVAC efficiency (lowering energy bills), and creates a healthier environment for your family. If anyone in your home suffers from allergies or respiratory issues, clean ducts make a real difference.

Our 5-Step Cleaning Process

1

Inspection & Assessment

We inspect your entire HVAC system, check all supply and return vents, identify problem areas, and document current conditions with photos.

2

HEPA Vacuum Setup

Our commercial-grade HEPA vacuum connects to your ductwork, creating negative pressure to capture all loosened debris without releasing particles into your home.

3

Rotary Brush Cleaning

Specialized rotary brushes agitate and loosen years of accumulated dust, debris, and contaminants from the interior walls of your ductwork.

4

Sanitization

We apply an EPA-registered antimicrobial sanitizer throughout the duct system to eliminate bacteria, mold spores, and odor-causing organisms.

5

Final Inspection

A thorough final inspection ensures every vent is clean. We provide before/after photos and walk you through the results so you can see the difference.

Frequently Asked Questions

How often should I get my air ducts cleaned?

The National Air Duct Cleaners Association (NADCA) recommends cleaning your air ducts every 3 to 5 years. If you have pets, allergies, smokers in the home, or have recently completed renovations, you may need cleaning more frequently — every 2 to 3 years.

How long does air duct cleaning take?

A typical residential air duct cleaning takes 2 to 4 hours depending on the size of your home and the number of vents. Larger homes or systems with significant buildup may take longer. We always complete a thorough job rather than rushing.

What's included in your air duct cleaning service?

Our service includes a full system inspection, HEPA vacuum cleaning of all supply and return ducts, rotary brush agitation, sanitization treatment, and before/after photo documentation so you can see the results.

Do you move furniture during the cleaning?

We handle everything. If furniture is blocking a vent or return, our technicians will carefully move it to access the ductwork and return it to its original position when finished.

What's the difference between HEPA and regular vacuum cleaning?

HEPA (High-Efficiency Particulate Air) vacuums capture 99.97% of particles as small as 0.3 microns, including dust mites, mold spores, and bacteria. Regular vacuums let fine particles escape back into the air. We exclusively use HEPA-grade equipment for every job.
