Straight answers, not scare tactics. Every service page says when you can skip the work.

Not Sure Which Service You Need?

Start with what you notice. Dust blowing out of registers, a musty smell when the AC kicks on, a dryer that needs two cycles, a bedroom that never cools down — each points to a different fix, and some of those fixes have nothing to do with cleaning.

The problem guides list the likely causes first, including the cheap ones, then name the service that solves what's left.

Three Questions That Narrow It Down

  1. Is something wrong, or is it just time? The EPA does not recommend routine duct cleaning — only cleaning when there's a reason.
  2. Is the problem dirt, damage or moisture? Leaks and wet insulation need repair before any cleaning helps.
  3. Is it the ducts or an exhaust vent? Dryer, kitchen and bathroom exhaust are separate systems.

Air Duct Cleaning: Which Scope Fits Your Home?

NADCA treats the whole forced-air system as one job — ducts, registers, plenum, coil and blower. These services differ by how much of that system needs attention and by what put the dirt there.

Residential Air Duct Cleaning

Whole-system cleaning for single-family homes and townhomes: supply and return runs, registers, plenum and blower.

Residential cleaning

Whole House Air Duct Cleaning

Every duct, every register and the air handler in one visit, with camera footage before and after.

Whole house cleaning

HVAC Duct Cleaning

Ductwork plus the equipment it connects to — blower compartment, coil face and condensate drain pan.

HVAC duct cleaning

Air Vent Cleaning

Registers, grilles and boots cleaned — plus a straight answer on what vent-only cleaning leaves behind.

Air vent cleaning

Furnace Duct Cleaning

Heating-side ducts and the furnace blower, best scheduled before the heating season starts.

Furnace duct cleaning

AC Duct Cleaning

Cooling-side ducts, coil and drain pan — where summer condensation creates the conditions mold needs.

AC duct cleaning

Dirty & Dusty Air Duct Cleaning

Heavy debris that actually blows out of supply registers — one of the three reasons the EPA gives for cleaning.

Dirty duct cleaning

Post-Construction Air Duct Cleaning

Drywall dust, sawdust and debris pulled into ductwork during a remodel, basement finish or addition.

Post-construction cleaning

New Home Air Duct Cleaning

Builder dust in a newly built home, cleared before a year of running the system spreads it through every room.

Indoor Air Quality: Mold, Odors, Allergies and Pets

These pages deal with contamination rather than ordinary dust. The EPA's position shapes every one of them: cleaning removes mold and debris you can see, but it has never been shown to prevent health problems.

Air Duct Mold Remediation

Confirmed mold removed from hard duct surfaces at the source — and wet or moldy duct insulation replaced, because it can't be cleaned.

Air Duct Sanitizing

What an EPA-registered antimicrobial treatment can do after cleaning, and why a clean system rarely needs one.

Duct sanitizing

Air Duct Disinfection

Cleaning, sanitizing and disinfecting compared — and the promises no contractor can legally make about ductwork.

Duct disinfection

Air Duct Odor Removal

Musty, pet, smoke and burning smells traced to their source before anything gets cleaned or treated.

Odor removal

Air Duct Cleaning for Allergies

What duct cleaning can and can't do for allergy and asthma households during Virginia's spring pollen season.

Cleaning for allergies

Pet Hair Air Duct Cleaning

Hair and dander packed into return ducts and filters in homes with dogs or cats that shed.

Inspection, Sealing and Repair: Fixing the Ductwork Itself

Look first, then fix. Leaky joints and torn flex duct waste conditioned air and pull attic or crawl space dust into the system — repair them before paying for any cleaning.

Air Duct Inspection

A camera look inside the ducts and equipment, so you see the condition before anyone quotes a price.

Duct inspection

Air Duct Leak Detection

Finding where conditioned air escapes into attics, wall cavities and crawl spaces.

Leak detection

Air Duct Sealing

Leaks at joints and seams closed with mastic or approved foil tape — a different job from spraying sealant inside ducts.

Duct sealing

Air Duct Repair

Torn flex duct, crushed or sagging runs and disconnected boots fixed before the system is cleaned.

Duct repair

Ductwork by Location: Attic, Crawl Space and Basement

Where the ducts run changes the job. Attic heat, crawl space moisture and finished basement ceilings each cause different problems and need different access work.

Attic Duct Cleaning

Duct runs in hot attic space, where flex duct tears easily and leaky joints pull in insulation dust.

Attic ducts

Crawl Space Duct Cleaning

Ductwork in damp crawl spaces, where condensation and pests do most of the damage.

Crawl space ducts

Basement Duct Cleaning

Trunk lines and returns in unfinished and finished basements, including runs closed in behind drywall ceilings.

Basement ducts

Whole-Home Ventilation Cleaning

Supply, return, bathroom and kitchen exhaust handled together as the connected airflow system they are.

Whole-home ventilation

Dryer Vents and Home Exhaust: Fire Safety and Moisture

Dryer, kitchen and bathroom exhaust are separate from your HVAC ducts. Dryer vents are the fire-safety job: U.S. Fire Administration data put home clothes dryer fires at about 2,900 a year, with failure to clean as the leading factor.

Dryer Vent Cleaning

Lint cleared from the full exhaust run to the outside hood — the maintenance that addresses the leading cause of dryer fires.

Dryer vent cleaning

Dryer Vent Repair

Crushed, disconnected or overlong dryer ducts rebuilt to the building code's length and material limits.

Dryer vent repair

Dryer Vent Inspection

Airflow, run length and exterior termination checked — useful at move-in, before a sale or between tenants.

Dryer vent inspection

Bird Nest & Lint Removal

Nests and packed lint cleared from exterior vent hoods, then the opening protected without blocking airflow.

Nest and lint removal

Townhome & HOA Dryer Vents

Long horizontal and roof-terminated dryer runs — the layouts that clog fastest — in townhome and HOA communities.

Townhome dryer vents

Kitchen Range Hood Duct Cleaning

Cooking grease and dust cleared from the duct between your kitchen hood and its outside cap, so the fan pulls smoke and steam out again.

Kitchen range hood ducts

Bathroom Exhaust Fan Cleaning

Fan housing and duct cleared so shower moisture leaves the house instead of settling where mold grows.

Duct and Vent Service FAQs

What should be included in air duct cleaning?

A proper cleaning covers the whole forced-air system, not just the ducts. NADCA lists the supply and return ducts, registers and grilles, plenum, coils, drain pan, blower motor and assembly, heat exchanger and air filter. Skipping a dirty component lets it recontaminate the ducts you just paid to have cleaned.

What is the best air duct cleaning method?

Source removal. Technicians loosen debris with rotating brushes, air whips or compressed-air nozzles while a vacuum holds the entire system under continuous negative pressure. The negative pressure pulls loosened dust out of the house instead of into your rooms. NADCA's standard is built on this method, and a shop vacuum at the registers does not meet it.

Should you sanitize your air ducts?

Usually not. The EPA says research has not shown biocides work inside ducts, and no products are registered for fiberglass-lined ducts or duct board. NADCA advises using an EPA-registered antimicrobial only after mechanical cleaning, only when contamination calls for it, and exactly as the label directs. It also says technicians should not claim ductwork is sanitized or disinfected.

Do duct cleaners have cameras?

Many do. The EPA notes that some providers use remote photography to document conditions inside ducts, and it calls a visual inspection the best way to confirm a thorough job. Ask for camera footage before cleaning and again afterward. Every part of the system should look clean, with no debris visible.
